<big>'''Geospace Environment Modeling (GEM)'''</big> [[Image:NSF_Logo_color.jpg|100 px]]

Geospace Environment Modeling (GEM) is a broad-based, community-initiated research program on the physics of the Earth's magnetosphere and the coupling of the magnetosphere to the atmosphere and to the solar wind. The purpose of the GEM program is to support basic research into the dynamical and structural properties of geospace, leading to the construction of a global Geospace General Circulation Model (GGCM) with predictive capability. This GGCM model will be modularized and will complement parallel developments of magnetohydrodynamic models. The strategy for achieving GEM goals is to undertake a series of campaigns and focus groups, in both theory and observational modes, each focusing on particular aspects of the geospace environment.

The Geospace Environment Modeling (GEM) program is sponsored by [http://www.nsf.gov/div/index.jsp?div=AGS National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences].

== Steering Committee ==

The GEM Steering Committee (SC) oversees all GEM activities, except funding. The SC consists of the Chair, Chair-elect, 4 science community representatives, the research area coordinators (see below), and the GEM meeting organizer (MO). [''See amendment below for additional voting members.''] These are the voting members. A quorum requires the votes (in person or via e-mail) of at least half the voting members and the chair. The chair's vote breaks a tie. Votes per e-mail are permissible and are solicited by the chair. When casting an e-mail vote the voting member should e-mail the vote to all other voting members.

''Amended 2017-Dec-10'': The two active student representatives are also voting members of the SC.

The SC elects a successor when a member, except the chair, rotates out and the SC Chair appoints the new member. A new SC chair-elect will be elected by the SC and appointed by the outgoing chair. The chair-elect serves for two years, and after that period automatically becomes the new chair to serve in that capacity for another two years. The science community representatives serve a term of 3 years. Care shall be taken that the voting members cover a broad range of GEM activities and interests and that the terms are staggered to maintain corporate memory.

(transition rule, can be deleted in 2010: In the transition, the current chair serves out his term until the completion of the 2009 summer workshop. A chair-elect will be elected at the Fall 2008 SC meeting and appointed by the current chair. (S)he becomes chair at the summer 2009 workshop. At that meeting also a new chair-elect will be elected.)

In addition to the voting members, the SC consists of the Student Representative, the GEM communications coordinator(s), liaisons to NASA, NOAA, CEDAR and SHINE, international liaisons, and the GEM program manager.

The GEM meeting organizer (MO) shall keep minutes of the each SC meeting. The minutes, excluding sensitive matters, shall be published in the GEM newsletter in a timely manner.

== Research Area Coordinators ==

Each research area (RA) within GEM has 2 Research Area Coordinators (RACs), who serve a staggered 6-year term. The SC elects Research Area Coordinators which are appointed by the PM. At present, there are 5 research areas. However, the SC may change this arrangement:

# Dayside, including boundary layers and plasma/energy entry.
# Inner magnetosphere and storms.
# Tail, including plasma sheet and substorms.
# Magnetosphere - ionosphere coupling, aurora.
# Global General Circulation Modeling (GGCM)

The general purpose of the GGCM Research Area is to include focus groups that fall within the scope of the GEM program but cross more than one of the other RAs (Dayside, IMS, Tail, and M-I Coupling). GGCM includes developing, validating, and comparing analytic, first-principles numerical, and data-based models of geospace environment that span more than one region and that lead to the development of a global description of the geospace. Activities appropriate for GGCM include, but are not limited to, use and development of multiple and/or coupled models or standalone models describing more than one region, designing and implementing "metrics" studies, support and extension of modeling "challenges" from focus groups in this and other research areas, and providing formal partnership with other organizations or institutions that support GGCM-relevant research in collaboration with GEM.

The Research Area Coordinators:

* Oversee the focus groups under their purview and ensure that the focus groups adhere to the activities spelled out in their proposals. For focus groups that fall under the purview of several RAs all RACs share that responsibility.
* Ensure that the FG sessions keep formal presentations short and allow sufficient time for discussion. Each FG session should have at least one RAC in attendance who takes notes and reports to the SC and in the GEM newsletter.
* Report to the SC at the SC meetings on the activities of those focus groups. For focus groups that fall under several RAs the respective RACs decide who should include that focus group in their report.
* Publish a report on the FG activities in the GEM newsletter within 6 weeks following the summer/fall workshops.
* Ensure that the FGs under their purview close out in due time and publish a report on their activities and findings within 5 months after the final Focus Group meeting. [''Revised 2015-Dec-13'']
* Solicit nominations for tutorial speakers from their FGs and invite the tutorial speakers.

''Note: Starting from 2014, the names of the five Research Areas are "Solar Wind Magnetosphere Interaction" (SWMI), "Inner Magnetosphere" (IMAG), "Magnetotail and Plasma Sheet" (MPS), "Magnetosphere Ionosphere Coupling" (MIC), and "Global System Modeling" (GSM), following the recommendations by the [http://gem.epss.ucla.edu/mediawiki/pdf/GEMWhitePaper-2013.07.01.pdf GEM 2013 White Paper].''

== Student Represenatives ==

A new student representative (SR) is elected by the students every year and serves a two-year term, overlapping with the term of the previous SR. The SR organizes and runs the student sessions, i.e., talks and tutorials given by students for students, on the day preceding the summer workshop. (S)he reports to the SC on the student activities. The SR from the previous year advises the currently active SR.

== Focus Groups ==

Focus Groups (FG) are at the heart of GEM. FGs are proposed by the community. The proposal shall be brief, no more than 4 pages (including figures), and must include:

* An abstract of the Focus Group proposal.
* A description of the topic.
* A statement on the timeliness of the FG idea.
* A description of how the FG would relate to existing FGs.
* A specific goal that includes a deliverable. Deliverables can be GGCM modules, empirical relations that lead to modules, solutions to specific science problems, challenges, data sets for validation and metrics, or paper collections.
* The names of the proposed co-chairs.
* The Research Area with which it will be associated.
* The length of the term, not more than 4 years, and a justification for the term length. [''Revised 2019-Aug-23'']
* Expected activities, for example, topics of WG sessions or challenges and approaches to encourage an interactive “GEM-Style” focus group.

''Amended 2019-Aug-23'': Focus Groups run for up to 4 years. In the fourth year (no later than the Tuesday of the summer workshop), Focus Group leadership may ask the SC to extend to a 5th year. Written justification for the extension shall be submitted to the GEM Chair and Vice-Chair, and it will be considered by the SC.

The FG co-chairs are expected to organize sessions at the summer workshop, and, if appropriate, also at the pre-AGU Mini-GEM workshop. There is no set number of sessions that an FG should organize, but 2-3 sessions are considered to be typical.

The SC issues a call for FG proposals in early Fall of each year, with a deadline the week before the Mini-GEM workshop in December. ''Amended 2019-Aug-23'': Proposals will be sent to the SC. A breakout session at the Mini-GEM workshop will be held to allow proposers to present their proposals. The SC discusses the proposals and votes at its Fall Mini-GEM meeting which FGs to implement. The target number of active FGs at any time is ~12. Thus, there will be ~2-3 new FGs selected every year. ''Amended 2019-Aug-23'': After selection, the selected FGs will be given a page on the GEM website where they should post their successful proposal and use for FG activities.

''Amended 2015-Dec-13'': Every ended FG shall, within 5 months after its final meeting, deliver to its Research Area Coordinators a report that is either ready for publication in the GEMstone Newsletter or in consideration of publication elsewhere. The final report briefly outlines the Focus Group activities, accomplishments, GGCM contributions, and resulting publications, and it will be part of the GEM 5-year report.

''Amended 2017-Jun-18'': Voting members of the Steering Committee shall not be allowed to be leader of a new FG.

''Amended 2017-Jun-18'': Steering Committee members that are involved in the leadership of a proposed focus group shall not be present during its discussion and vote.

''Amended 2019-Aug-23'': Graduate students are not permitted to be a chair or co-chair of a focus group.

''Criteria for focus group selection (Added 2019-Aug-23):''

Focus groups are selected by the voting members of the Steering Committee following in-depth discussion of each focus group proposal/presentation and a thorough discussion of the merits and weaknesses of each. Steering Committee members have the latitude to make their own determination of which proposal(s) should be selected. However, there are some guiding principles that typically should be taken into account (in no particular order):

* The scientific merits and timeliness of the proposed research;
* The fit of the science with the GEM program and GEM priorities;
* The fit of the focus group with other focus groups;
* The overlap of the focus group with other focus groups;
* The deliverables being compelling and realistic;
* The plans for making the focus group activities interactive and “GEM-style”;
* The justification for the term;
* The abilities and experiences of the leadership team to lead a productive focus group.

== Summer Workshop Plenary Tutorials ==

The student representative invites one tutorial speaker who gives the "student sponsored tutorial." The FG chairs suggest the other speakers for the plenary tutorials at the summer workshop. The area coordinators decide on the invitees.

== The Communications Coordinator ==

The communication's coordinator provides the communication infrastructure for the GEM effort through the following activities:

* Issues the electronic GEM Messenger containing short news items pertinent to the affairs of GEM. These include working group reports, meeting announcements, calls for participation and similar messages. Requires maintaining an up-to-date mailing list, allowing those listed to remove themselves from the list, and maintaining the security of that list so that it is not used by those not associated with GEM or copied by them. This is a mediated newsletter under the active control of an editor who must be fully engaged 365 days a year.
* Issues the electronic GEMstone containing an annual report on the status of the GEM project, centered on the activities at the annual (summer) meeting. Issued at least once per year, usually no more than twice. Paper copies are available. Uses the GEM Messenger mailing list. This newsletter requires the active collection of information in contrast to the GEM Messenger that responds to member requests for issuance.
* Maintains the GEM web page describing the organization, providing access to GEM documents, allowing the posting of tutorial presentations and working group presentations as requested. Allows virtual poster sessions for those not being able to attend GEM although this has not been used much recently. Provides the historical archive of GEM activities.
* Provides access to data, mainly ground-based magnetometer data, in support of campaigns and general community research. Provides support for campaigns by providing a home for data sets used for joint studies. However, as individual groups become more adept and have greater storage capacity themselves, this has become less necessary.
* Leads the preparation of the seven-year report whenever it is requested. This has happened only once thus far.

The coordinators are selected and funded by peer-reviewed proposals to NSF.

<big>'''Geospace Environment Modeling (GEM)'''</big> [[Image:NSF_Logo_color.jpg|100 px]]

Geospace Environment Modeling (GEM) is a broad-based, community-initiated research program on the physics of the Earth's magnetosphere and the coupling of the magnetosphere to the atmosphere and to the solar wind. The purpose of the GEM program is to support basic research into the dynamical and structural properties of geospace, leading to the construction of a global Geospace General Circulation Model (GGCM) with predictive capability. This GGCM model will be modularized and will complement parallel developments of magnetohydrodynamic models. The strategy for achieving GEM goals is to undertake a series of campaigns and focus groups, in both theory and observational modes, each focusing on particular aspects of the geospace environment.

The Geospace Environment Modeling (GEM) program is sponsored by [http://www.nsf.gov/div/index.jsp?div=AGS National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences].

== What's New ==

* The 2019 GEM Summer Workshop was held during June 22-28, 2019 at the La Fonda Hotel in Santa Fe, NM. Information about the Workshop can be found at the [http://gemworkshop.org conference website] and the [[2019 GEM-CEDAR Joint Workshop and GEM Workshop|2019 Workshop Wiki Page]].

* The GEM Steering Committee has selected two new Focus Groups for the 2019-2023 period: (i) “System understanding of radiation belt particle dynamics through multi-spacecraft and ground-based observations and modeling” led by Hong Zhao, Lauren Blum, Sasha Ukhorskiy, and Xiangrong Fu, and (ii) “Particle heating and thermalization in collisionless shocks in the MMS era”, led by Lynn Wilson III, Li-Jen Chen, Katherine Goodrich, and Ivan Vasko.

== GEM Community Knowledge Base ==

The science component of the GEM Workshops are led by a volunteer Steering Committee. To promote transparency and provide an informal guide to existing, new, and future members of the Steering Committee, a document of GEM Steering Committee Best Practices was developed. This document, updated in October 2019, is available [http://ulysses.phys.wvu.edu/~pcassak/temp/GEM_BestPractices_6Oct2019.pdf at this link].


The hallmark of GEM workshops is its community-led workshop-style sessions, carried out through focus groups. Interested in applying to run a focus group and are not sure how to do it? Are you currently running a focus group and need ideas for how to achieve the workshop-style in your focus groups?

== Steering Committee ==

The GEM Steering Committee (SC) oversees all GEM activities, except funding. The SC consists of the Chair, Chair-elect, 4 science community representatives, the research area coordinators (see below), and the GEM meeting organizer (MO). [''See amendment below for additional voting members.''] These are the voting members. A quorum requires the votes (in person or via e-mail) of at least half the voting members and the chair. The chair's vote breaks a tie. Votes per e-mail are permissible and are solicited by the chair. When casting an e-mail vote the voting member should e-mail the vote to all other voting members.

''Amended 2017-Dec-10'': The two active student representatives are also voting members of the SC.

The SC elects a successor when a member, except the chair, rotates out and the SC Chair appoints the new member. A new SC chair-elect will be elected by the SC and appointed by the outgoing chair. The chair-elect serves for two years, and after that period automatically becomes the new chair to serve in that capacity for another two years. The science community representatives serve a term of 3 years. Care shall be taken that the voting members cover a broad range of GEM activities and interests and that the terms are staggered to maintain corporate memory.

(transition rule, can be deleted in 2010: In the transition, the current chair serves out his term until the completion of the 2009 summer workshop. A chair-elect will be elected at the Fall 2008 SC meeting and appointed by the current chair. (S)he becomes chair at the summer 2009 workshop. At that meeting also a new chair-elect will be elected.)

In addition to the voting members, the SC consists of the Student Representative, the GEM communications coordinator(s), liaisons to NASA, NOAA, CEDAR and SHINE, international liaisons, and the GEM program manager.

The GEM meeting organizer (MO) shall keep minutes of the each SC meeting. The minutes, excluding sensitive matters, shall be published in the GEM newsletter in a timely manner.

== Research Area Coordinators ==

Each research area (RA) within GEM has 2 Research Area Coordinators (RACs), who serve a staggered 6-year term. The SC elects Research Area Coordinators which are appointed by the PM. At present, there are 5 research areas. However, the SC may change this arrangement:

# Dayside, including boundary layers and plasma/energy entry.
# Inner magnetosphere and storms.
# Tail, including plasma sheet and substorms.
# Magnetosphere - ionosphere coupling, aurora.
# Global General Circulation Modeling (GGCM)

The general purpose of the GGCM Research Area is to include focus groups that fall within the scope of the GEM program but cross more than one of the other RAs (Dayside, IMS, Tail, and M-I Coupling). GGCM includes developing, validating, and comparing analytic, first-principles numerical, and data-based models of geospace environment that span more than one region and that lead to the development of a global description of the geospace. Activities appropriate for GGCM include, but are not limited to, use and development of multiple and/or coupled models or standalone models describing more than one region, designing and implementing "metrics" studies, support and extension of modeling "challenges" from focus groups in this and other research areas, and providing formal partnership with other organizations or institutions that support GGCM-relevant research in collaboration with GEM.

The Research Area Coordinators:

* Oversee the focus groups under their purview and ensure that the focus groups adhere to the activities spelled out in their proposals. For focus groups that fall under the purview of several RAs all RACs share that responsibility.
* Ensure that the FG sessions keep formal presentations short and allow sufficient time for discussion. Each FG session should have at least one RAC in attendance who takes notes and reports to the SC and in the GEM newsletter.
* Report to the SC at the SC meetings on the activities of those focus groups. For focus groups that fall under several RAs the respective RACs decide who should include that focus group in their report.
* Publish a report on the FG activities in the GEM newsletter within 6 weeks following the summer/fall workshops.
* Ensure that the FGs under their purview close out in due time and publish a report on their activities and findings within 5 months after the final Focus Group meeting. [''Revised 2015-Dec-13'']
* Solicit nominations for tutorial speakers from their FGs and invite the tutorial speakers.

''Note: Starting from 2014, the names of the five Research Areas are "Solar Wind Magnetosphere Interaction" (SWMI), "Inner Magnetosphere" (IMAG), "Magnetotail and Plasma Sheet" (MPS), "Magnetosphere Ionosphere Coupling" (MIC), and "Global System Modeling" (GSM), following the recommendations by the [http://gem.epss.ucla.edu/mediawiki/pdf/GEMWhitePaper-2013.07.01.pdf GEM 2013 White Paper].''

== Student Represenatives ==

A new student representative (SR) is elected by the students every year and serves a two-year term, overlapping with the term of the previous SR. The SR organizes and runs the student sessions, i.e., talks and tutorials given by students for students, on the day preceding the summer workshop. (S)he reports to the SC on the student activities. The SR from the previous year advises the currently active SR.

== Focus Groups ==

Focus Groups (FG) are at the heart of GEM. FGs are proposed by the community. The proposal shall be brief, no more than 4 pages (including figures), and must include:

* An abstract of the Focus Group proposal.
* A description of the topic.
* A statement on the timeliness of the FG idea.
* A description of how the FG would relate to existing FGs.
* A specific goal that includes a deliverable. Deliverables can be GGCM modules, empirical relations that lead to modules, solutions to specific science problems, challenges, data sets for validation and metrics, or paper collections.
* The names of the proposed co-chairs.
* The Research Area with which it will be associated.
* The term, not more than 4 years, and a justification for the term. [''Revised 2019-Aug-23'']
* Expected activities, for example, topics of WG sessions or challenges and approaches to encourage an interactive “GEM-Style” focus group.

''Amended 2019-Aug-23'': Focus Groups run for up to 4 years. At the end of the 4 years, Focus Group leadership may ask the SC to extend to a 5th year (within one month of the summer workshop). Written justification for the extension shall be submitted to the GEM Chair and Vice-Chair, and it will be considered by the SC.

The FG co-chairs are expected to organize sessions at the summer workshop, and, if appropriate, also at the pre-AGU Mini-GEM workshop. There is no set number of sessions that an FG should organize, but 2-3 sessions are considered to be typical.

The SC issues a call for FG proposals in early Fall of each year, with a deadline the week before the Mini-GEM workshop in December. ''Amended 2019-Aug-23'': Proposals will be sent to the SC. A breakout session at the Mini-GEM workshop will be held to allow proposers to present their proposals. The SC discusses the proposals and votes at its Fall Mini-GEM meeting which FGs to implement. The target number of active FGs at any time is ~12. Thus, there will be ~2-3 new FGs selected every year. ''Amended 2019-Aug-23'': After selection, the selected FGs will be given a page on the GEM website where they should post their successful proposal and use for FG activities.

''Amended 2015-Dec-13'': Every ended FG shall, within 5 months after its final meeting, deliver to its Research Area Coordinators a report that is either ready for publication in the GEMstone Newsletter or in consideration of publication elsewhere. The final report briefly outlines the Focus Group activities, accomplishments, GGCM contributions, and resulting publications, and it will be part of the GEM 5-year report.

''Amended 2017-Jun-18'': Voting members of the Steering Committee shall not be allowed to be leader of a new FG.

''Amended 2017-Jun-18'': Steering Committee members that are involved in the leadership of a proposed focus group shall not be present during its discussion and vote.

''Amended 2019-Aug-23'': Graduate students are not permitted to be a chair or co-chair of a focus group.

''Criteria for focus group selection (Added 2019-Aug-23):''

Focus groups are selected by the voting members of the Steering Committee following in-depth discussion of each focus group proposal/presentation and a thorough discussion of the merits and weaknesses of each. Steering Committee members have the latitude to make their own determination of which proposal(s) should be selected. However, there are some guiding principles that typically should be taken into account (in no particular order):

* The scientific merits and timeliness of the proposed research;
* The fit of the science with the GEM program and GEM priorities;
* The fit of the focus group with other focus groups;
* The overlap of the focus group with other focus groups;
* The deliverables being compelling and realistic;
* The plans for making the focus group activities interactive and “GEM-style”;
* The justification for the term;
* The abilities and experiences of the leadership team to lead a productive focus group.

== Summer Workshop Plenary Tutorials ==

The student representative invites one tutorial speaker who gives the "student sponsored tutorial." The FG chairs suggest the other speakers for the plenary tutorials at the summer workshop. The area coordinators decide on the invitees.

== The Communications Coordinator ==

The communication's coordinator provides the communication infrastructure for the GEM effort through the following activities:

* Issues the electronic GEM Messenger containing short news items pertinent to the affairs of GEM. These include working group reports, meeting announcements, calls for participation and similar messages. Requires maintaining an up-to-date mailing list, allowing those listed to remove themselves from the list, and maintaining the security of that list so that it is not used by those not associated with GEM or copied by them. This is a mediated newsletter under the active control of an editor who must be fully engaged 365 days a year.
* Issues the electronic GEMstone containing an annual report on the status of the GEM project, centered on the activities at the annual (summer) meeting. Issued at least once per year, usually no more than twice. Paper copies are available. Uses the GEM Messenger mailing list. This newsletter requires the active collection of information in contrast to the GEM Messenger that responds to member requests for issuance.
* Maintains the GEM web page describing the organization, providing access to GEM documents, allowing the posting of tutorial presentations and working group presentations as requested. Allows virtual poster sessions for those not being able to attend GEM although this has not been used much recently. Provides the historical archive of GEM activities.
* Provides access to data, mainly ground-based magnetometer data, in support of campaigns and general community research. Provides support for campaigns by providing a home for data sets used for joint studies. However, as individual groups become more adept and have greater storage capacity themselves, this has become less necessary.
* Leads the preparation of the seven-year report whenever it is requested. This has happened only once thus far.

The coordinators are selected and funded by peer-reviewed proposals to NSF.

* Ensure that the FG sessions keep formal presentations short and allow sufficient time for discussion. Each FG session should have at least one RAC in attendance who takes notes and reports to the SC and in the GEM newsletter.
* Report to the SC at the SC meetings on the activities of those focus groups. For focus groups that fall under several RAs the respective RACs decide who should include that focus group in their report.
* Publish a report on the FG activities in the GEM newsletter within 6 weeks following the summer/fall workshops.
* Ensure that the FGs under their purview close out in due time and publish a report on their activities and findings within 5 months after the final Focus Group meeting. [''Revised 2015-Dec-13'']
* Solicit nominations for tutorial speakers from their FGs and invite the tutorial speakers.

''Note: Starting from 2014, the names of the five Research Areas are "Solar Wind Magnetosphere Interaction" (SWMI), "Inner Magnetosphere" (IMAG), "Magnetotail and Plasma Sheet" (MPS), "Magnetosphere Ionosphere Coupling" (MIC), and "Global System Modeling" (GSM), following the recommendations by the [http://gem.epss.ucla.edu/mediawiki/pdf/GEMWhitePaper-2013.07.01.pdf GEM 2013 White Paper].''

== Student Represenatives ==

A new student representative (SR) is elected by the students every year and serves a two-year term, overlapping with the term of the previous SR. The SR organizes and runs the student sessions, i.e., talks and tutorials given by students for students, on the day preceding the summer workshop. (S)he reports to the SC on the student activities. The SR from the previous year advises the currently active SR.

== Focus Groups ==

Focus Groups (FG) are at the heart of GEM. FGs are proposed by the community. The proposal shall be brief, no more than 4 pages (including figures), and must include:

* An abstract of the Focus Group proposal.
* A description of the topic.
* A statement on the timeliness of the FG idea.
* A description of how the FG would relate to existing FGs.
* A specific goal that includes a deliverable. Deliverables can be GGCM modules, empirical relations that lead to modules, solutions to specific science problems, challenges, data sets for validation and metrics, or paper collections.
* The names of the proposed co-chairs.
* The Research Area with which it will be associated.
* The term, not more than 4 years, and a justification for the term. [''Revised 2019-Aug-23'']
* Expected activities, for example, topics of WG sessions or challenges and approaches to encourage an interactive “GEM-Style” focus group.

''Amended 2019-Aug-23'': Focus Groups run for up to 4 years. At the end of the 4 years, Focus Group leadership may ask the SC to extend to a 5th year (within one month of the summer workshop). Written justification for the extension shall be submitted to the GEM Chair and Vice-Chair, and it will be considered by the SC.

The FG co-chairs are expected to organize sessions at the summer workshop, and, if appropriate, also at the pre-AGU Mini-GEM workshop. There is no set number of sessions that an FG should organize, but 2-3 sessions are considered to be typical.

The SC issues a call for FG proposals in early Fall of each year, with a deadline the week before the Mini-GEM workshop in December. ''Amended 2019-Aug-23'': Proposals will be sent to the SC. A breakout session at the GEM Mini-workshop will be held to allow proposers to present their proposals. The SC discusses the proposals and votes at its Fall Mini-GEM meeting which FGs to implement. The target number of active FGs at any time is ~12. Thus, there will be ~2-3 new FGs selected every year. ''Amended 2019-Aug-23'': After selection, the selected FGs will be given a page on the GEM website where they should post their successful proposal and use for FG activities.

''Amended 2015-Dec-13'': Every ended FG shall, within 5 months after its final meeting, deliver to its Research Area Coordinators a report that is either ready for publication in the GEMstone Newsletter or in consideration of publication elsewhere. The final report briefly outlines the Focus Group activities, accomplishments, GGCM contributions, and resulting publications, and it will be part of the GEM 5-year report.

''Amended 2017-Jun-18'': Voting members of the Steering Committee shall not be allowed to be leader of a new FG.

''Amended 2017-Jun-18'': Steering Committee members that are involved in the leadership of a proposed focus group shall not be present during its discussion and vote.

''Amended 2019-Aug-23'': Graduate students are not permitted to be a chair or co-chair of a focus group.

''Criteria for focus group selection (Added 2019-Aug-23):''

Focus groups are selected by the voting members of the Steering Committee following in-depth discussion of each focus group proposal/presentation and a thorough discussion of the merits and weaknesses of each. Steering Committee members have the latitude to make their own determination of which proposal(s) should be selected. However, there are some guiding principles that typically should be taken into account (in no particular order):

* The scientific merits and timeliness of the proposed research;
* The fit of the science with the GEM program and GEM priorities;
* The fit of the focus group with other focus groups;
* The overlap of the focus group with other focus groups;
* The deliverables being compelling and realistic;
* The plans for making the focus group activities interactive and “GEM-style”;
* The justification for the term;
* The abilities and experiences of the leadership team to lead a productive focus group.

== Summer Workshop Plenary Tutorials ==

The student representative invites one tutorial speaker who gives the "student sponsored tutorial." The FG chairs suggest the other speakers for the plenary tutorials at the summer workshop. The area coordinators decide on the invitees.

== The Communications Coordinator ==

The communication's coordinator provides the communication infrastructure for the GEM effort through the following activities:

* Issues the electronic GEM Messenger containing short news items pertinent to the affairs of GEM. These include working group reports, meeting announcements, calls for participation and similar messages. Requires maintaining an up-to-date mailing list, allowing those listed to remove themselves from the list, and maintaining the security of that list so that it is not used by those not associated with GEM or copied by them. This is a mediated newsletter under the active control of an editor who must be fully engaged 365 days a year.
* Issues the electronic GEMstone containing an annual report on the status of the GEM project, centered on the activities at the annual (summer) meeting. Issued at least once per year, usually no more than twice. Paper copies are available. Uses the GEM Messenger mailing list. This newsletter requires the active collection of information in contrast to the GEM Messenger that responds to member requests for issuance.
* Maintains the GEM web page describing the organization, providing access to GEM documents, allowing the posting of tutorial presentations and working group presentations as requested. Allows virtual poster sessions for those not being able to attend GEM although this has not been used much recently. Provides the historical archive of GEM activities.
* Provides access to data, mainly ground-based magnetometer data, in support of campaigns and general community research. Provides support for campaigns by providing a home for data sets used for joint studies. However, as individual groups become more adept and have greater storage capacity themselves, this has become less necessary.
* Leads the preparation of the seven-year report whenever it is requested. This has happened only once thus far.

The coordinators are selected and funded by peer-reviewed proposals to NSF.

== Steering Committee ==

The GEM Steering Committee (SC) oversees all GEM activities, except funding. The SC consists of the Chair, Chair-elect, 4 science community representatives, the research area coordinators (see below), and the GEM meeting organizer (MO). [''See amendment below for additional voting members.''] These are the voting members. A quorum requires the votes (in person or via e-mail) of at least half the voting members and the chair. The chair's vote breaks a tie. Votes per e-mail are permissible and are solicited by the chair. When casting an e-mail vote the voting member should e-mail the vote to all other voting members.

''Amended 2017-Dec-10'': The two active student representatives are also voting members of the SC.

The SC elects a successor when a member, except the chair, rotates out and the SC Chair appoints the new member. A new SC chair-elect will be elected by the SC and appointed by the outgoing chair. The chair-elect serves for two years, and after that period automatically becomes the new chair to serve in that capacity for another two years. The science community representatives serve a term of 3 years. Care shall be taken that the voting members cover a broad range of GEM activities and interests and that the terms are staggered to maintain corporate memory.

(transition rule, can be deleted in 2010: In the transition, the current chair serves out his term until the completion of the 2009 summer workshop. A chair-elect will be elected at the Fall 2008 SC meeting and appointed by the current chair. (S)he becomes chair at the summer 2009 workshop. At that meeting also a new chair-elect will be elected.)

In addition to the voting members, the SC consists of the Student Representative, the GEM communications coordinator(s), liaisons to NASA, NOAA, CEDAR and SHINE, international liaisons, and the GEM program manager.

The GEM meeting organizer (MO) shall keep minutes of the each SC meeting. The minutes, excluding sensitive matters, shall be published in the GEM newsletter in a timely manner.

== Research Area Coordinators ==

Each research area (RA) within GEM has 2 Research Area Coordinators (RACs), who serve a staggered 6-year term. The SC elects Research Area Coordinators which are appointed by the PM. At present, there are 5 research areas. However, the SC may change this arrangement:

# Dayside, including boundary layers and plasma/energy entry.
# Inner magnetosphere and storms.
# Tail, including plasma sheet and substorms.
# Magnetosphere - ionosphere coupling, aurora.
# Global General Circulation Modeling (GGCM)

The general purpose of the GGCM Research Area is to include focus groups that fall within the scope of the GEM program but cross more than one of the other RAs (Dayside, IMS, Tail, and M-I Coupling). GGCM includes developing, validating, and comparing analytic, first-principles numerical, and data-based models of geospace environment that span more than one region and that lead to the development of a global description of the geospace. Activities appropriate for GGCM include, but are not limited to, use and development of multiple and/or coupled models or standalone models describing more than one region, designing and implementing "metrics" studies, support and extension of modeling "challenges" from focus groups in this and other research areas, and providing formal partnership with other organizations or institutions that support GGCM-relevant research in collaboration with GEM.

The Research Area Coordinators:

* Oversee the focus groups under their purview and ensure that the focus groups adhere to the activities spelled out in their proposals. For focus groups that fall under the purview of several RAs all RACs share that responsibility.
* Ensure that the FG sessions keep formal presentations short and allow sufficient time for discussion. Each FG session should have at least one RAC in attendance who takes notes and reports to the SC and in the GEM newsletter.
* Report to the SC at the SC meetings on the activities of those focus groups. For focus groups that fall under several RAs the respective RACs decide who should include that focus group in their report.

== Student Represenatives ==

A new student representative (SR) is elected by the students every year and serves a two-year term, overlapping with the term of the previous SR. The SR organizes and runs the student sessions, i.e., talks and tutorials given by students for students, on the day preceding the summer workshop. (S)he reports to the SC on the student activities. The SR from the previous year advises the currently active SR.

== Focus Groups ==

Focus Groups (FG) are at the heart of GEM. FGs are proposed by the community. The proposal shall be brief, no more than 4 pages (including figures), and must include:

* An abstract of the Focus Group proposal.
* A description of the topic.
* A statement on the timeliness of the FG idea.
* A description of how the FG would relate to existing FGs.
* A specific goal that includes a deliverable. Deliverables can be GGCM modules, empirical relations that lead to modules, solutions to specific science problems, challenges, data sets for validation and metrics, or paper collections.
* The names of the proposed co-chairs.
* The Research Area with which it will be associated.
* The term, not more than 4 years, and a justification for the term. [''Revised 2019-Aug-23'']
* Expected activities, for example, topics of WG sessions or challenges and approaches to encourage an interactive “GEM-Style” focus group..

''Amended 2019-Aug-23'': Focus Groups run for up to 4 years. At the end of the 4 years, Focus Group leadership may ask the SC to extend to a 5th year (within one month of the summer workshop). Written justification for the extension shall be submitted to the GEM Chair and Vice-Chair, and it will be considered by the SC.

The FG co-chairs are expected to organize sessions at the summer workshop, and, if appropriate, also at the pre-AGU Mini-GEM workshop. There is no set number of sessions that an FG should organize, but 2-3 sessions are considered to be typical.

The SC issues a call for FG proposals in early Fall of each year, with a deadline the week before the Mini-GEM workshop in December. ''Amended 2019-Aug-23'': Proposals will be sent to the SC. A breakout session at the GEM Mini-workshop will be held to allow proposers to present their proposals. The SC discusses the proposals and votes at its Fall Mini-GEM meeting which FGs to implement. The target number of active FGs at any time is ~12. Thus, there will be ~2-3 new FGs selected every year. ''Amended 2019-Aug-23'': After selection, the selected FGs will be given a page on the GEM website where they should post their successful proposal and use for FG activities.

''Amended 2015-Dec-13'': Every ended FG shall, within 5 months after its final meeting, deliver to its Research Area Coordinators a report that is either ready for publication in the GEMstone Newsletter or in consideration of publication elsewhere. The final report briefly outlines the Focus Group activities, accomplishments, GGCM contributions, and resulting publications, and it will be part of the GEM 5-year report.

''Amended 2017-Jun-18'': Voting members of the Steering Committee shall not be allowed to be leader of a new FG.

''Amended 2017-Jun-18'': Steering Committee members that are involved in the leadership of a proposed focus group shall not be present during its discussion and vote.

''Amended 2019-Aug-23'': Graduate students are not permitted to be a chair or co-chair of a focus group.

''Criteria for focus group selection:''

Focus groups are selected by the voting members of the Steering Committee following in-depth discussion of each focus group proposal/presentation and a thorough discussion of the merits and weaknesses of each. Steering Committee members have the latitude to make their own determination of which proposal(s) should be selected. However, there are some guiding principles that typically should be taken into account (in no particular order):

*(1) The scientific merits and timeliness of the proposed research;
*(2) The fit of the science with the GEM program and GEM priorities;
*(3) The fit of the focus group with other focus groups;
*(4) The overlap of the focus group with other focus groups;
*(5) The deliverables being compelling and realistic;
*(6) The plans for making the focus group activities interactive and “GEM-style”;
*(7) The justification for the term;
*(8) The abilities and experiences of the leadership team to lead a productive focus group.

== Summer Workshop Plenary Tutorials ==

The student representative invites one tutorial speaker who gives the "student sponsored tutorial." The FG chairs suggest the other speakers for the plenary tutorials at the summer workshop. The area coordinators decide on the invitees.

== The Communications Coordinator ==

The communication's coordinator provides the communication infrastructure for the GEM effort through the following activities:

* Issues the electronic GEM Messenger containing short news items pertinent to the affairs of GEM. These include working group reports, meeting announcements, calls for participation and similar messages. Requires maintaining an up-to-date mailing list, allowing those listed to remove themselves from the list, and maintaining the security of that list so that it is not used by those not associated with GEM or copied by them. This is a mediated newsletter under the active control of an editor who must be fully engaged 365 days a year.
* Issues the electronic GEMstone containing an annual report on the status of the GEM project, centered on the activities at the annual (summer) meeting. Issued at least once per year, usually no more than twice. Paper copies are available. Uses the GEM Messenger mailing list. This newsletter requires the active collection of information in contrast to the GEM Messenger that responds to member requests for issuance.
* Maintains the GEM web page describing the organization, providing access to GEM documents, allowing the posting of tutorial presentations and working group presentations as requested. Allows virtual poster sessions for those not being able to attend GEM although this has not been used much recently. Provides the historical archive of GEM activities.
* Provides access to data, mainly ground-based magnetometer data, in support of campaigns and general community research. Provides support for campaigns by providing a home for data sets used for joint studies. However, as individual groups become more adept and have greater storage capacity themselves, this has become less necessary.
* Leads the preparation of the seven-year report whenever it is requested. This has happened only once thus far.

The coordinators are selected and funded by peer-reviewed proposals to NSF.

== Steering Committee ==

The GEM Steering Committee (SC) oversees all GEM activities, except funding. The SC consists of the Chair, Chair-elect, 4 science community representatives, the research area coordinators (see below), and the GEM meeting organizer (MO). [''See amendment below for additional voting members.''] These are the voting members. A quorum requires the votes (in person or via e-mail) of at least half the voting members and the chair. The chair's vote breaks a tie. Votes per e-mail are permissible and are solicited by the chair. When casting an e-mail vote the voting member should e-mail the vote to all other voting members.

''Amended 2017-Dec-10'': The two active student representatives are also voting members of the SC.

The SC elects a successor when a member, except the chair, rotates out and the SC Chair appoints the new member. A new SC chair-elect will be elected by the SC and appointed by the outgoing chair. The chair-elect serves for two years, and after that period automatically becomes the new chair to serve in that capacity for another two years. The science community representatives serve a term of 3 years. Care shall be taken that the voting members cover a broad range of GEM activities and interests and that the terms are staggered to maintain corporate memory.

(transition rule, can be deleted in 2010: In the transition, the current chair serves out his term until the completion of the 2009 summer workshop. A chair-elect will be elected at the Fall 2008 SC meeting and appointed by the current chair. (S)he becomes chair at the summer 2009 workshop. At that meeting also a new chair-elect will be elected.)

In addition to the voting members, the SC consists of the Student Representative, the GEM communications coordinator(s), liaisons to NASA, NOAA, CEDAR and SHINE, international liaisons, and the GEM program manager.

The GEM meeting organizer (MO) shall keep minutes of the each SC meeting. The minutes, excluding sensitive matters, shall be published in the GEM newsletter in a timely manner.

== Research Area Coordinators ==

Each research area (RA) within GEM has 2 Research Area Coordinators (RACs), who serve a staggered 6-year term. The SC elects Research Area Coordinators which are appointed by the PM. At present, there are 5 research areas. However, the SC may change this arrangement:

# Dayside, including boundary layers and plasma/energy entry.
# Inner magnetosphere and storms.
# Tail, including plasma sheet and substorms.
# Magnetosphere - ionosphere coupling, aurora.
# Global General Circulation Modeling (GGCM)

The general purpose of the GGCM Research Area is to include focus groups that fall within the scope of the GEM program but cross more than one of the other RAs (Dayside, IMS, Tail, and M-I Coupling). GGCM includes developing, validating, and comparing analytic, first-principles numerical, and data-based models of geospace environment that span more than one region and that lead to the development of a global description of the geospace. Activities appropriate for GGCM include, but are not limited to, use and development of multiple and/or coupled models or standalone models describing more than one region, designing and implementing "metrics" studies, support and extension of modeling "challenges" from focus groups in this and other research areas, and providing formal partnership with other organizations or institutions that support GGCM-relevant research in collaboration with GEM.

The Research Area Coordinators:

* Oversee the focus groups under their purview and ensure that the focus groups adhere to the activities spelled out in their proposals. For focus groups that fall under the purview of several RAs all RACs share that responsibility.
* Ensure that the FG sessions keep formal presentations short and allow sufficient time for discussion. Each FG session should have at least one RAC in attendance who takes notes and reports to the SC and in the GEM newsletter.
* Report to the SC at the SC meetings on the activities of those focus groups. For focus groups that fall under several RAs the respective RACs decide who should include that focus group in their report.
* Publish a report on the FG activities in the GEM newsletter within 6 weeks following the summer/fall workshops.

* Report to the SC at the SC meetings on the activities of those focus groups. For focus groups that fall under several RAs the respective RACs decide who should include that focus group in their report.
* Publish a report on the FG activities in the GEM newsletter within 6 weeks following the summer/fall workshops.
* Ensure that the FGs under their purview close out in due time and publish a report on their activities and findings within 5 months after the final Focus Group meeting. [''Revised 2015-Dec-13'']
* Solicit nominations for tutorial speakers from their FGs and invite the tutorial speakers.

''Note: Starting from 2014, the names of the five Research Areas are "Solar Wind Magnetosphere Interaction" (SWMI), "Inner Magnetosphere" (IMAG), "Magnetotail and Plasma Sheet" (MPS), "Magnetosphere Ionosphere Coupling" (MIC), and "Global System Modeling" (GSM), following the recommendations by the [http://gem.epss.ucla.edu/mediawiki/pdf/GEMWhitePaper-2013.07.01.pdf GEM 2013 White Paper].''

== Student Represenatives ==

A new student representative (SR) is elected by the students every year and serves a two-year term, overlapping with the term of the previous SR. The SR organizes and runs the student sessions, i.e., talks and tutorials given by students for students, on the day preceding the summer workshop. (S)he reports to the SC on the student activities. The SR from the previous year advises the currently active SR.

== Focus Groups ==

Focus Groups (FG) are at the heart of GEM. FGs are proposed by the community. The proposal shall be brief, no more than 4 pages (including figures), and must include:

* An abstract of the Focus Group proposal.
* A description of the topic.
* A statement on the timeliness of the FG idea.
* A description of how the FG would relate to existing FGs.
* A specific goal that includes a deliverable. Deliverables can be GGCM modules, empirical relations that lead to modules, solutions to specific science problems, challenges, data sets for validation and metrics, or paper collections.
* The names of the proposed co-chairs.
* The Research Area with which it will be associated.
* The term, not more than ''Amended 2019-Aug-23": 4 years.
* Expected activities, for example, topics of WG sessions or challenges and approaches to encourage an interactive “GEM-Style” focus group..

''Amended 2019-Aug-23'': Focus Groups run for up to 4 years. At the end of the 4 years, Focus Group leadership may ask the SC to extend to a 5th year (within one month of the summer workshop). Written justification for the extension shall be submitted to the GEM Chair and Vice-Chair, and it will be considered by the SC.

The FG co-chairs are expected to organize sessions at the summer workshop, and, if appropriate, also at the pre-AGU Mini-GEM workshop. There is no set number of sessions that an FG should organize, but 2-3 sessions are considered to be typical.

The SC issues a call for FG proposals in early Fall of each year, with a deadline the week before the Mini-GEM workshop in December. ''Amended 2019-Aug-23'': Proposals will be sent to the SC. A breakout session at the GEM Mini-workshop will be held to allow proposers to present their proposals. The SC discusses the proposals and votes at its Fall Mini-GEM meeting which FGs to implement. The target number of active FGs at any time is ~12. Thus, there will be ~2-3 new FGs selected every year. ''Amended 2019-Aug-23'': After selection, the selected FGs will be given a page on the GEM website where they should post their successful proposal and use for FG activities.

''Amended 2015-Dec-13'': Every ended FG shall, within 5 months after its final meeting, deliver to its Research Area Coordinators a report that is either ready for publication in the GEMstone Newsletter or in consideration of publication elsewhere. The final report briefly outlines the Focus Group activities, accomplishments, GGCM contributions, and resulting publications, and it will be part of the GEM 5-year report.

''Amended 2017-Jun-18'': Voting members of the Steering Committee shall not be allowed to be leader of a new FG.

''Amended 2017-Jun-18'': Steering Committee members that are involved in the leadership of a proposed focus group shall not be present during its discussion and vote.

''Amended 2019-Aug-23'': Graduate students are not permitted to be a chair or co-chair of a focus group.

''Criteria for focus group selection:''
Focus groups are selected by the voting members of the Steering Committee following in-depth discussion of each focus group proposal/presentation and a thorough discussion of the merits and weaknesses of each. Steering Committee members have the latitude to make their own determination of which proposal(s) should be selected. However, there are some guiding principles that typically should be taken into account (in no particular order):
(1) The scientific merits and timeliness of the proposed research;
(2) The fit of the science with the GEM program and GEM priorities;
(3) The fit of the focus group with other focus groups;
(4) The overlap of the focus group with other focus groups;
(5) The deliverables being compelling and realistic;
(6) The plans for making the focus group activities interactive and “GEM-style”;
(7) The justification for the term;
(8) The abilities and experiences of the leadership team to lead a productive focus group.

== Summer Workshop Plenary Tutorials ==

The student representative invites one tutorial speaker who gives the "student sponsored tutorial." The FG chairs suggest the other speakers for the plenary tutorials at the summer workshop. The area coordinators decide on the invitees.

== The Communications Coordinator ==

The communication's coordinator provides the communication infrastructure for the GEM effort through the following activities:

* Issues the electronic GEM Messenger containing short news items pertinent to the affairs of GEM. These include working group reports, meeting announcements, calls for participation and similar messages. Requires maintaining an up-to-date mailing list, allowing those listed to remove themselves from the list, and maintaining the security of that list so that it is not used by those not associated with GEM or copied by them. This is a mediated newsletter under the active control of an editor who must be fully engaged 365 days a year.
* Issues the electronic GEMstone containing an annual report on the status of the GEM project, centered on the activities at the annual (summer) meeting. Issued at least once per year, usually no more than twice. Paper copies are available. Uses the GEM Messenger mailing list. This newsletter requires the active collection of information in contrast to the GEM Messenger that responds to member requests for issuance.
* Maintains the GEM web page describing the organization, providing access to GEM documents, allowing the posting of tutorial presentations and working group presentations as requested. Allows virtual poster sessions for those not being able to attend GEM although this has not been used much recently. Provides the historical archive of GEM activities.
* Provides access to data, mainly ground-based magnetometer data, in support of campaigns and general community research. Provides support for campaigns by providing a home for data sets used for joint studies. However, as individual groups become more adept and have greater storage capacity themselves, this has become less necessary.
* Leads the preparation of the seven-year report whenever it is requested. This has happened only once thus far.

The coordinators are selected and funded by peer-reviewed proposals to NSF.

==== [FG] (Joint) Magnetic Reconnection in the Magnetosphere + Tail Environment and Dynamics at Lunar Distances + Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere ====

Location: Holley Ballroom

In these joint sessions, we will be focusing on the connections between magnetic reconnection, dipolarization events, and plasmoids in Earth’s magnetotail. The first session will kick off with a short (~20 min) introduction by Prof. Vassilis Angelopoulos covering a very brief review of the system and how each of these three FGs are related. Then, we will take the remaining time in the sessions to move into an open discussion on the following questions/topics:

#The role of various instability processes in the original onset and perpetuation of reconnection in the magnetotail (Session 1)
#Comparing and contrasting the qualities of earthward vs. tailward jets of reconnection in the magnetotail (dipolarizing flux bundles / bubbles vs. plasmoids). Comparing and contrasting the qualities of dipolarizing flux bundles/bubbles/plasmoids between near-Earth and mid-tail. (Sessions 1 and 2)
#The forces driving the spatiotemporal evolution of dipolarizing flux bundles / bubbles and plasmoids and how they both interact with the ambient plasma through which they are moving (e.g., can they themselves trigger additional reconnection???) (Session 2)
#Definitions and concepts and what various subsets of the community mean when they say things like dipolarization front; magnetotail dipolarization; extended X-line; X-line motion; plasmoid; etc. Basically, are we all speaking the same language here? (wrap-up activity at the end of the Session 2 if we have any time)

We want to stress that these sessions will be run in an informal nature; we will not be asking for any formal presentations from participants. Instead, we solicit the community to contribute with informal slides, figures, and/or plots to stress key points on any of the above topics. We hope that this session will inspire audience interaction and open discussion and/or debate. If you would like to contribute in these sessions, please just show up with any material you have and join us in going with the flow of the discussion!

Discussion on other topics related to the two focus groups is welcome.

We plan to have most of the time driven by discussion. Time permitting, we would like community members to pose a science question or challenge that they would like to see other people address (e.g., “is it possible to observe/simulate this feature I’ve simulated/observed?”). We would also like to have time to brainstorm on open questions. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> or Heli Hietala < heli at igpp.ucla.edu> with questions.

==== [FG] (Joint) Magnetic Reconnection in the Magnetosphere + Tail Environment and Dynamics at Lunar Distances + Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere ====

Location: Holley Ballroom

In these joint sessions, we will be focusing on the connections between magnetic reconnection, dipolarization events, and plasmoids in Earth’s magnetotail. The first session will kick off with a short (~20 min) introduction by Prof. Vassilis Angelopoulos covering a very brief review of the system and how each of these three FGs are related. Then, we will take the remaining time in the sessions to move into an open discussion on the following questions/topics:

#The role of various instability processes in the original onset and perpetuation of reconnection in the magnetotail (Session 1)
#Comparing and contrasting the qualities of earthward vs. tailward jets of reconnection in the magnetotail (dipolarizing flux bundles / bubbles vs. plasmoids). Comparing and contrasting the qualities of dipolarizing flux bundles/bubbles/plasmoids between near-Earth and mid-tail. (Sessions 1 and 2)
#The forces driving the spatiotemporal evolution of dipolarizing flux bundles / bubbles and plasmoids and how they both interact with the ambient plasma through which they are moving (e.g., can they themselves trigger additional reconnection???) (Session 2)
#Definitions and concepts and what various subsets of the community mean when they say things like dipolarization front; magnetotail dipolarization; extended X-line; X-line motion; plasmoid; etc. Basically, are we all speaking the same language here? (wrap-up activity at the end of the Session 2 if we have any time)

We want to stress that these sessions will be run in an informal nature; we will not be asking for any formal presentations from participants. Instead, we solicit the community to contribute with informal slides, figures, and/or plots to stress key points on any of the above topics. We hope that this session will inspire audience interaction and open discussion and/or debate. If you would like to contribute in these sessions, please just show up with any material you have and join us in going with the flow of the discussion!

==== [FG] (Joint) Magnetic Reconnection in the Magnetosphere + Tail Environment and Dynamics at Lunar Distances + Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere ====

Location: Holley Ballroom

In these joint sessions, we will be focusing on the connections between magnetic reconnection, dipolarization events, and plasmoids in Earth’s magnetotail. The first session will kick off with a short (~20 min) introduction by Prof. Vassilis Angelopoulos covering a very brief review of the system and how each of these three FGs are related. Then, we will take the remaining time in the sessions to move into an open discussion on the following questions/topics:

The role of various instability processes in the original onset and perpetuation of reconnection in the magnetotail (Session 1)
Comparing and contrasting the qualities of earthward vs. tailward jets of reconnection in the magnetotail (dipolarizing flux bundles / bubbles vs. plasmoids). Comparing and contrasting the qualities of dipolarizing flux bundles/bubbles/plasmoids between near-Earth and mid-tail. (Sessions 1 and 2)
The forces driving the spatiotemporal evolution of dipolarizing flux bundles / bubbles and plasmoids and how they both interact with the ambient plasma through which they are moving (e.g., can they themselves trigger additional reconnection???) (Session 2)
Definitions and concepts and what various subsets of the community mean when they say things like dipolarization front; magnetotail dipolarization; extended X-line; X-line motion; plasmoid; etc. Basically, are we all speaking the same language here? (wrap-up activity at the end of the Session 2 if we have any time)

We want to stress that these sessions will be run in an informal nature; we will not be asking for any formal presentations from participants. Instead, we solicit the community to contribute with informal slides, figures, and/or plots to stress key points on any of the above topics. We hope that this session will inspire audience interaction and open discussion and/or debate. If you would like to contribute in these sessions, please just show up with any material you have and join us in going with the flow of the discussion!

===2017 GEM Workshop Plans===

We are excited to announce plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop. This is the final year of this focus group, and we would like to thank everyone who has participated in it.

This year, the reconnection focus group has 5 sessions overall, 3 of which are joint and 2 are solo. The (currently scheduled) dates, times, and summaries for each session are:

====Monday 6/19, PM1 and PM2 - 1:30-3:00pm and 3:30-5:00pm (Joint sessions with “Tail Environment and Dynamics at Lunar Distances” and “Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere” focus groups)====

(wrap-up activity at the end of the Session 2 if we have any time)

We want to stress that these sessions will be run in an informal nature; we will not be asking for any formal presentations from participants.

We hope that this session will inspire audience interaction and open discussion and/or debate. If you would like to contribute in these sessions, please just show up with any material you have and join us in going with the flow of the discussion!

====Tuesday 6/20, PM1 - 1:30-3:00pm (individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any topic relevant to the focus group as interest dictates. Please contact Brian Walsh <bwalsh at bu.edu> with questions.

====Wednesday 6/21, PM1 - 1:30-3:00pm (individual session)====

This session will be a continuation of the open forum from Tuesday. We also would like to spend some time discussing community interest in proposing a new reconnection focus group. Discussion on topics for the next group to address are invited, as this is a grass roots effort. Please contact Yi-Hsin Liu <Yi-Hsin.Liu at Dartmouth.edu> with questions.

====Thursday 6/22, PM2 - 3:30-5:00pm (Joint session with “Dayside Kinetic Processes in Global Solar Wind - Magnetosphere Interaction” focus group)====

This session will focus on discussing the following science topics: 1) Kinetic physics of dayside and/or magnetosheath reconnection - dissipation, energy conversion, particle acceleration, and comparisons between the two regions, 2) Do kinetic bow shock and magnetosheath transients impact magnetopause reconnection?, and 3) Does kinetic physics at the dayside impact the global reconnection process? Discussion on other topics related to the two focus groups is welcome.

We plan to have most of the time driven by discussion. Time permitting, we would like community members to pose a science question or challenge that they would like to see other people address (e.g., “is it possible to observe/simulate this feature I’ve simulated/observed?”). We would also like to have time to brainstorm on open questions. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> or Heli Hietala < heli at igpp.ucla.edu> with questions.

===2016 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop.

We have a broad collection of sessions planned for this year, including both basic reconnection science and joint sessions with focus groups where reconnection plays a role in the broader dynamics. The sessions are intended to be driven by open discussion, but attendees are encouraged to enhance the discussion by showing a slide or two as appropriate. As in the past, we are asking participants to not do AGU-style presentations. As always, we will try to accommodate all who want to speak, but the priority is having open and active discussion over sticking to a schedule. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Monday 6/20, PM1 - 1:30pm-3:30pm (Individual session)====

This session will focus on kinetic physics in day- and night-side reconnection. With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). We also encourage discussion on other relevant topics. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you are interested in being part of the discussion.

====Monday 6/20, PM2 - 4:00pm-6:00pm (Joint with Mesoscale Auroral and Polar Cap Dynamics and Substorms focus groups)====

We will discuss the following topics:

-- Ionospheric signatures of magnetopause reconnection and FTEs

-- Possible dayside-nightside coupling (remote observations, modeling, tests for in-situ multi-point observations)

-- The role of the ionosphere in transient day- and night-side reconnection-related processes

Contributions from ground- and space-based observers as well as from modelers are welcome. Please contact Brian Walsh <bwalsh at bu.edu> if you are interested in being part of the discussion.

====Tuesday 6/21, PM1 - 1:30pm-3:30pm (Joint with Dayside Kinetic and Transient Phenomena focus groups)====

This session will encourage cross-focus group interaction and open ended discussion on the topics of magnetopause reconnection, flux-transfer events, Kelvin-Helmholtz instability, magnetopause waves, and other boundary layer processes. Talks on MMS-related studies and modeling with the emphasis on global magnetospheric aspects of reconnection are especially encouraged. Please contact Yi-Hsin Liu <yi-hsin.liu at nasa.gov> by Friday, June 10 if you are interested in being part of the discussion.

====Friday 6/24, PM1 - 1:30pm-3:30pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any of the earlier sessions as interest dictates. In addition, there will be an update on efforts to incorporate kinetic modeling into NASA’s CCMC. We also hope there is time for a discussion on topics of interest for next year, and the potential future of the reconnection focus group beyond when the current version ends next year. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you would like to offer a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions.

===2015 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting. We also welcome Yi-Hsin Liu and Brian Walsh to our team of co-chairs, and offer thanks to Homa Karimabadi for his years of service.

Last year, we employed two "scene setting" talks per session to frame relevant questions and generate discussion for the remainder of the session. We intend to use a similar strategy this year. We are in the process of lining up speakers, but if you would like to nominate someone (including a self-nomination) for any of the sessions listed below, please email Paul.Cassak at mail.wvu.edu with the name(s) and a brief justification.

Others are encouraged to enhance the discussion by showing a slide or two as appropriate, and we expect some time for open discussion. As in the past, we are asking participants to not do AGU-style presentations, opting for discussion and real-time progress instead. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Tuesday 6/16, 1:30pm-3:00pm (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)====

This session will focus on reconnection in the magnetotail and its effects on the inner magnetosphere. In particular, a topic that has generated a lot of interest of late are the kinetic processes associated with energy conversion and the formation and consequences of dipolarization fronts. We also encourage discussion on reconnection onset in the magnetotail - tearing vs. ballooning/interchange. Other relevant topics are welcome.

====Wednesday 6/17, 3:30pm-5:00pm (Joint with "Metrics and Validation" Focus Group)====

The Magnetospheric Multiscale (MMS) satellites were recently launched to measure the electron dissipation region during magnetic reconnection. NASA's Community Coordinated Modeling Center (CCMC), a repository of codes and models with runs-on-request, is pursuing support of MMS science, including the implementation of particle-in-cell simulations to their portfolio. This session will include a discussion of what capabilities members of the community (modelers and observers alike) would like from CCMC for MMS science.

====Thursday 6/18, 1:30pm-3:00pm (Joint with "Geospace System Science"Focus Group)====

This session will encourage cross-focus group interaction and open ended discussion on the topic of "What is the interplay between local and global processes in regulating reconnection?" This can include local-scale (Alfven speeds, microphysics, plasma state and composition, magnetic field geometry), meso-scale (geometry of the magnetic configuration, impediment of outflows), and global-scale (magnetospheric geometry and inflation, current closure through the magnetosheath, ionospheric conductivity, ionospheric outflows). We expect observers, theorists, and modelers interested in the magnetosphere as a system will find this session interesting.

====Thursday 6/18, 3:30pm-5:00pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. We expect dayside reconnection to be a main topic of this session. We encourage discussion on topics of local vs. global control of dayside reconnection and the role of diamagnetic effects and flow shear on dayside reconnection. We encourage people interested in opening a discussion on a topic (the ones listed or otherwise) to attend. Please email Paul.Cassak at mail.wvu.edu by June 9 if you would like to propose a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions, and see you in Snowmass.

===2014 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the
Magnetosphere" Focus Group sessions at the upcoming GEM Meeting.

The format for each is to have two speakers set the scene on a
particular topic. Others are encouraged to contribute to the
discussion and put up a slide or two as relevant. Half of one session
will be for general contributions consisting of no more than 4 slides
- 1 for intro to acclimate graduate students, and no more than 3 on
your topic. If you would like to be considered for one of the general
contributions, please email Paul.Cassak at mail.wvu.edu with your
topic. We will try to accommodate as many of the requests for talks
as possible. We strongly encourage everyone wishing to present to
sign up to give a poster to ensure you are able to present more than a
few slides. Please let one of the focus group chairs know if you have
any comments or questions.

The dates, times, locations, and summaries for each session are
described here:

====Monday 6/16, 10:30am-12:15pm, Ports Ballroom I-III====
First half - "What controls the rate of dayside reconnection?"
Scene-setters - Joe Borovsky and Ramon Lopez
Science - It has long been thought that the reconnection rate at the
dayside is controlled by the electric field in the solar wind. Recent
observations that geomagnetic indices are affected by plasmaspheric
drainage plumes called this into question, suggesting local control of
the reconnection rate. This session will tackle this fundamental
question of importance to solar wind-magnetospheric coupling. We will
hear from proponents on each side and discuss how future progress will
be made on these questions.

Second half - "General Contributions"
Scene-setters - None
Science - Please consider contributing a few slides on any topic on
reconnection (provided it is GEM relevant). Observations, modeling,
and theory presentations are encouraged. Again, since we are only
leaving 45 minutes for this session, all potential contributors are
encouraged to also sign up to give a poster.

====Monday 6/16, 1:30pm-3:00pm, Ports Ballroom I-III====
First half - "What determines the cross-tail scale of reconnection
jets?"
Scene-setters - Phil Pritchett and Jiang Liu
Science - Multi-satellite missions have made it accessible to study
the three-dimensional structure of reconnection in the
magnetotail. Observationally, what is the characteristic length in
the out-of-plane direction of the reconnection events? Theoretically,
what physically sets this length? These topics will be discussed in
this session.

Second half - "How is magnetotail reconnection modulated by dayside
reconnection? What is the nature of magnetotail reconnection onset
and transients?"
Scene-setters - Toshi Nishimura and Joachim Birn
Science - Reconnection in the magnetotail onsets abruptly, and is
often bursty. It can further be modulated due to time-dependent
phenomena on the dayside. This session will discuss how reconnection
in the magnetotail responds to modulation from the dayside and what
causes reconnection onset and transients in the
magnetotail. Observational and theoretical/modeling considerations
will be discussed.

====Monday 6/16, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)=====
Scene-setters - Misha Sitnov and Andrei Runov
Science - This joint session will focus on the relationship between
bursty bulk flows/dipolarization fronts and reconnection, both from
the observational and theoretical/modeling perspective. In many ways,
this is a continuation of the1:30-3:00 session, but additional
attention will be paid to
the ramifications on the inner magnetosphere.

====Abstract====
Magnetic reconnection underlies the dynamics in many aspects of magnetospheric
physics and is critical to the development of a predictive understanding of space weather
phenomena. It importance spans from the dayside where solar wind-magnetospheric coupling
occurs to the nightside where storm and substorm phenomena occur. Many existing Focus
Groups treat reconnection in the context of a particular application, but a Focus Group
specifically on reconnection is being proposed to develop an understanding that could not be
attained from studies on particular applications. Broadly, the proposed Focus Group will
address kinetic physics of reconnection and how it couples to macroscales, reconnection at the
dayside and its relation to solar wind-magnetospheric coupling, three-dimensional reconnection,
reconnection onset and transient behavior and implications for transport, and particle
acceleration in reconnection. The proposed Focus Group is timely as simulations have matured
to the point where they can offer realistic comparisons to observations, and the existing
THEMIS/ARTEMIS and upcoming MMS missions include reconnection physics as a key feature
of their goals. Reconnection is by nature cross-disciplinary and offers many opportunities for
interaction with existing Focus Groups. The proposed reconnection Focus Group is for five
years, and will produce deliverables of import for many aspects of GEM goals.

==== Topic Description ====

During magnetic reconnection, a change in magnetic topology facilitates the conversion
of magnetic energy to kinetic and thermal energy and allows mixing of plasmas on either side of
current sheets. It is the driver of many dynamical behaviors in the magnetosphere that are of
crucial importance to space weather. At the dayside magnetopause, reconnection plays a
critical role in solar wind-magnetospheric coupling and recent evidence suggests it may even
control the coupling efficiency. This process is the driver of magnetospheric convection,
evolution of the radiation belts, and loading of energy in the magnetotail. The release of this
energy in geomagnetic storms and substorms is a result of reconnection in the magnetotail.
Reconnection also produces energetic particles that can damage satellites. At present,
magnetic reconnection is studied separately under the auspices of particular applications within
separate GEM Focus Groups. The proposed Focus Group will address the physics of
reconnection as a distinct physical process which is important for magnetospheric applications
in ways that cannot be addressed in applied settings. There is a long history of success in GEM
on reconnection (including the highly-cited GEM Reconnection Challenge). The proposed
Focus Group will foster interaction between observations, simulations, and models. The broad
goals of the Reconnection Focus Group are to contribute to the understanding of (1) the kinetic
microphysics of reconnection and how it couples to the magnetosphere at macroscales, (2) how
and where dayside reconnection occurs and how it contributes to solar wind-magnetospheric
coupling including the role of flux transfer events, (3) how three-dimensional reconnection
proceeds, especially at the dayside, (4) the onset of reconnection and the physics of transient
reconnection events and their relation to bursty bulk flows, dipolarization fronts, and entropy
bubbles, and (5) how reconnection produces energetic particles. Recent advances in fluid and
kinetic simulations both locally at reconnection sites and globally containing the whole
magnetosphere have led to a point where realistic numerical models can be compared directly
with satellite observations. The Focus Group will benefit from a wealth of observational data
from existing satellites, as well as new highly resolved multi-point observational data from the
THEMIS/ARTEMIS mission and the upcoming Magnetospheric MultiScale (MMS) mission.
Strong ties with existing Focus Groups studying applications of reconnection will be made.

==== Timeliness of the Focus Group ====

A GEM Focus Group on magnetic reconnection is particularly timely. NASAs
Magnetospheric MultiScale (MMS) Mission, with a planned launch date of October of 2014,
"will use Earth's magnetosphere as a laboratory to study magnetic reconnection" (http://
mms.gsfc.nasa.gov/about_mms.html), focussing on the kinetic-scale microphysics. This
requires spacecraft to be closer together than previous missions and will provide unprecedented
observational resolution. The three-probe THEMIS constellation will also be reconfigured to
form a larger scale tetrahedron with MMS at one node to provide the macroscopic context for
the microscopic measurements by MMS. In addition, the ARTEMIS satellites repurposed from
the THEMIS mission have recently moved into a lunar orbit and will provide information on the
mid-tail region where reconnection is expected to occur and serve as a solar wind monitor on
the dayside. Therefore, near-future in-situ observations will provide measurements at a wide
scale range from the electron kinetic scale to the global scale. In the run-up to launch of MMS,
a GEM Focus Group on reconnection emphasizing numerical and observational studies will play
a central role in preparing for the mission by investigating what signals should be expected and
in what locations of the magnetosphere. After the launch of MMS, the GEM Focus Group will be
an avenue for analyzing and interpreting the data with comparisons to simulations and for
putting the newly obtained knowledge in context of larger-scale magnetospheric behavior.

==== Relation to Existing GEM Focus Groups ====

As magnetic reconnection underlies dynamics in every GEM Research Area, this Focus
Group has enormous potential for interaction with existing Focus Groups. It is the goal of this Focus Group to both support existing efforts in other Focus Groups and to drive new avenues of research through discovery achieved in this Focus Group. A non-exhaustive discussion follows for ways in which a reconnection Focus Group is synergistic with existing Focus Groups. For each example listed, the Co-Chairs of the existing Focus Group have been contacted and agree that interdisciplinary activities with a reconnection Focus Group would be desirable.

# Plasmasphere-Magnetosphere Interactions (2008-13) - The PMI Focus Group is an example where previous incarnations of reconnection studies at GEM have successfully had interdisciplinary activities. The previous reconnection focus group produced studies on asymmetric reconnection and how it may occur at the dayside magnetosphere. Recent studies showed that solar wind-magnetospheric coupling is less efficient when high density plasmaspheric drainage plumes reach the dayside reconnection site. This is consistent with reconnection becoming less efficient when asymmetric reconnection occurs with high density plasma. A presentation on this was given in a PMI session. Though the PMI Focus Group will end soon, it is expected that the previous interdisciplinary activities will continue.
# Substorm Expansion Onset: The First 10 Minutes (2008-13) - This is another example where there has been cross-participation in the past. The physics of dipolarization fronts and how they can be used to understand reconnection onset in substorms is common to both groups, as it was recently determined that they occur at the onset of reconnection. Kinetic simulations have been very useful to understand their properties.
# Magnetosheath (2010-14) - The magnetosheath is strongly linked to dayside reconnection physics. Many issues of the structure of the magnetosheath are related to how reconnection proceeds, such as the appearance or lack of flux pile-up at the magnetopause and the propensity for flux transfer events. Understanding how kinetic effects impact dayside reconnection and the march to global kinetic modeling, and where reconnection at the dayside occurs as a function of solar wind conditions, are both synergistic topics.
# Metrics and Validation (2011-15) - This group addresses challenges of model-data comparisons and how to assess them. In the past, a barrier to performing careful metrics and validation studies of magnetic reconnection has been a lack of sufficient observations, but the MMS mission is expected to change this. Therefore, a potential avenue for collaboration with the Metrics and Validation Focus Group is comparisons of kinetic modeling and observational data from MMS.
# Tail-Inner Magnetosphere Interactions (2012-16) - This Focus Group addresses modes of transport that cause heating in the magnetotail and inner magnetosphere. It is thought that transient events such as bursty bulk flows, entropy bubbles, and dipolarization fronts play a potentially important role. As these events are associated with magnetotail reconnection, there is strong potential for cross-disciplinary interactions with this Focus Group.

====Goals and Deliverables====

The goals of the Reconnection Focus Group are to understand aspects of
magnetospheric reconnection with an eye to applications in other Focus Groups. This list is not
exhaustive, but it has been compiled using input from the GEM community.

# What is the physics of reconnection at the kinetic scale and how does it couple to the magnetosphere at macro-scales? Particular topics include the role of the extended electron diffusion region, pressure anisotropies, normal magnetic fields for magnetotail applications, asymmetries in density and magnetic field, and whether or how the microphysics of reconnection can be incorporated into fluid models in geospace general circulation models (GGCMs). Examples of deliverables for simulation and modeling work include answers to the following questions - What sets the scale of the extended electron diffusion region and what is its effect on reconnection? (This will be important both before and after the launch of MMS for locating and analyzing reconnection events.) How do asymmetries effect the kinetic signatures of reconnection? Under what conditions do pressure anisotropies arise? Observational deliverables include THEMIS/ARTEMIS and MMS results, which will be compared to numerical simulations.
# How does reconnection proceed at the dayside and how does it contribute to solar wind-magnetospheric coupling? Topics include the role of asymmetries and shear flow in setting the efficiency of reconnection and the role of flux transfer events. Deliverables include quantitative predictions of dayside reconnection efficiency as a function of solar wind conditions that can be fed into solar wind-magnetospheric coupling functions as in the Borovsky coupling function and expected properties of flux transfer events in kinetic simulations and observations.
# How does three-dimensional reconnection proceed, especially at the dayside? Numerical deliverables include answering these questions - What is the location of reconnection on the dayside and its efficiency as a function of solar wind conditions? What differences are there between in 2D and fully 3D reconnection? Observational deliverables include signatures of the dissipation region in fully 3D settings and their meso- and macro-scale ramifications.
# How does reconnection onset and what is the physics of transient reconnection events such as bursty bulk flows, dipolarization fronts, entropy bubbles, and flux transfer events? Deliverables include how their properties depend on magnetospheric conditions, their role in energy and mass transport, how they expand and spread as a function of time, and comparisons with observational data from the THEMIS/ARTEMIS mission.
# How are energetic particles produced during reconnection? This includes mechanisms based on reconnection electric fields and secondary islands. Deliverables include the relative importance of various particle acceleration mechanisms and the observational signatures that result, and observations of these events from THEMIS/ARTEMIS and MMS.

Five years (2013-2017)

====Expected Activities, Session Topics, and Challenges====

The following are a possible set of activities and session topics for the duration of the
proposed Focus Group. This list is not intended to be binding, nor is it intended to be noninclusive
to research in areas planned for other years, but is offered as a guide to the direction
of the Focus Group.
Year 1, Signatures of Kinetic Scale Reconnection Physics (2013) - This is important in the runup
to the launch of the MMS mission. The state-of-the-art in kinetic simulations will be gathered
and discussed in relation to existing observational data to make predictions for MMS.
Year 2, Dayside Reconnection and Solar Wind-Magnetospheric Coupling (2014) - This activity
will collect progress in determining how reconnection occurs at the magnetopause and how it
impacts solar wind-magnetospheric coupling. Cross-disciplinary activities with the
Magnetosheath group are possible.
Year 3, Kinetic Physics of Reconnection and Particle Acceleration (2015) - With early results
from MMS expected, this session will focus on analyzing this data and comparing it to numerical
simulations. It is expected that particle acceleration will be a strong component of the
observations. Cross-disciplinary activities with the Metrics and Validation group are possible.
Year 4, Reconnection Onset and Transients (2016) - This session will address the role of
transients and reconnection onset. Cross-disciplinary activities with the Tail-Inner
Magnetosphere Interactions group are possible.
Year 5, Understanding Three-dimensional Reconnection (2017) - Efforts on the challenging and
largely unknown physics of three-dimensional reconnection will be gathered and discussed.

===2017 GEM Workshop Plans===

We are excited to announce plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop. This is the final year of this focus group, and we would like to thank everyone who has participated in it.

This year, the reconnection focus group has 5 sessions overall, 3 of which are joint and 2 are solo. The (currently scheduled) dates, times, and summaries for each session are:

====Monday 6/19, PM1 and PM2 - 1:30-3:00pm and 3:30-5:00pm (Joint sessions with “Tail Environment and Dynamics at Lunar Distances” and “Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere” focus groups)====

In these joint sessions, we will be focusing on the connections between magnetic reconnection, dipolarization events, and plasmoids in Earth’s magnetotail. The first session will kick off with a short (~20 min) introduction by Prof. Vassilis Angelopoulos covering a very brief review of the system and how each of these three FGs are related. Then, we will take the remaining time in the sessions to move into an open discussion on the following questions/topics:

1) The role of various instability processes in the original onset and perpetuation of reconnection in the magnetotail (Session 1)
2) Comparing and contrasting the qualities of earthward vs. tailward jets of reconnection in the magnetotail (dipolarizing flux bundles / bubbles vs. plasmoids). Comparing and contrasting the qualities of dipolarizing flux bundles/bubbles/plasmoids between near-Earth and mid-tail. (Sessions 1 and 2)
3) The forces driving the spatiotemporal evolution of dipolarizing flux bundles / bubbles and plasmoids and how they both interact with the ambient plasma through which they are moving (e.g., can they themselves trigger additional reconnection???) (Session 2)
4) Definitions and concepts and what various subsets of the community mean when they say things like dipolarization front; magnetotail dipolarization; extended X-line; X-line motion; plasmoid; etc. Basically, are we all speaking the same language here? (wrap-up activity at the end of the Session 2 if we have any time)

We want to stress that these sessions will be run in an informal nature; we will not be asking for any formal presentations from participants. Instead, we solicit the community to contribute with informal slides, figures, and/or plots to stress key points on any of the above topics. We hope that this session will inspire audience interaction and open discussion and/or debate. If you would like to contribute in these sessions, please just show up with any material you have and join us in going with the flow of the discussion!

====Tuesday 6/20, PM1 - 1:30-3:00pm (individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any topic relevant to the focus group as interest dictates. Please contact Brian Walsh <bwalsh at bu.edu> with questions.

====Wednesday 6/21, PM1 - 1:30-3:00pm (individual session)====

This session will be a continuation of the open forum from Tuesday. We also would like to spend some time discussing community interest in proposing a new reconnection focus group. Discussion on topics for the next group to address are invited, as this is a grass roots effort. Please contact Yi-Hsin Liu <Yi-Hsin.Liu at Dartmouth.edu> with questions.

====Thursday 6/22, PM2 - 3:30-5:00pm (Joint session with “Dayside Kinetic Processes in Global Solar Wind - Magnetosphere Interaction” focus group)====

This session will focus on discussing the following science topics: 1) Kinetic physics of dayside and/or magnetosheath reconnection - dissipation, energy conversion, particle acceleration, and comparisons between the two regions, 2) Do kinetic bow shock and magnetosheath transients impact magnetopause reconnection?, and 3) Does kinetic physics at the dayside impact the global reconnection process? Discussion on other topics related to the two focus groups is welcome.

We plan to have most of the time driven by discussion. Time permitting, we would like community members to pose a science question or challenge that they would like to see other people address (e.g., “is it possible to observe/simulate this feature I’ve simulated/observed?”). We would also like to have time to brainstorm on open questions. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> or Heli Hietala < heli at igpp.ucla.edu> with questions.

===2016 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop.

We have a broad collection of sessions planned for this year, including both basic reconnection science and joint sessions with focus groups where reconnection plays a role in the broader dynamics. The sessions are intended to be driven by open discussion, but attendees are encouraged to enhance the discussion by showing a slide or two as appropriate. As in the past, we are asking participants to not do AGU-style presentations. As always, we will try to accommodate all who want to speak, but the priority is having open and active discussion over sticking to a schedule. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Monday 6/20, PM1 - 1:30pm-3:30pm (Individual session)====

This session will focus on kinetic physics in day- and night-side reconnection. With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). We also encourage discussion on other relevant topics. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you are interested in being part of the discussion.

====Monday 6/20, PM2 - 4:00pm-6:00pm (Joint with Mesoscale Auroral and Polar Cap Dynamics and Substorms focus groups)====

We will discuss the following topics:

-- Ionospheric signatures of magnetopause reconnection and FTEs

-- Possible dayside-nightside coupling (remote observations, modeling, tests for in-situ multi-point observations)

-- The role of the ionosphere in transient day- and night-side reconnection-related processes

Contributions from ground- and space-based observers as well as from modelers are welcome. Please contact Brian Walsh <bwalsh at bu.edu> if you are interested in being part of the discussion.

====Tuesday 6/21, PM1 - 1:30pm-3:30pm (Joint with Dayside Kinetic and Transient Phenomena focus groups)====

This session will encourage cross-focus group interaction and open ended discussion on the topics of magnetopause reconnection, flux-transfer events, Kelvin-Helmholtz instability, magnetopause waves, and other boundary layer processes. Talks on MMS-related studies and modeling with the emphasis on global magnetospheric aspects of reconnection are especially encouraged. Please contact Yi-Hsin Liu <yi-hsin.liu at nasa.gov> by Friday, June 10 if you are interested in being part of the discussion.

====Friday 6/24, PM1 - 1:30pm-3:30pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any of the earlier sessions as interest dictates. In addition, there will be an update on efforts to incorporate kinetic modeling into NASA’s CCMC. We also hope there is time for a discussion on topics of interest for next year, and the potential future of the reconnection focus group beyond when the current version ends next year. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you would like to offer a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions.

===2015 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting. We also welcome Yi-Hsin Liu and Brian Walsh to our team of co-chairs, and offer thanks to Homa Karimabadi for his years of service.

Last year, we employed two "scene setting" talks per session to frame relevant questions and generate discussion for the remainder of the session. We intend to use a similar strategy this year. We are in the process of lining up speakers, but if you would like to nominate someone (including a self-nomination) for any of the sessions listed below, please email Paul.Cassak at mail.wvu.edu with the name(s) and a brief justification.

Others are encouraged to enhance the discussion by showing a slide or two as appropriate, and we expect some time for open discussion. As in the past, we are asking participants to not do AGU-style presentations, opting for discussion and real-time progress instead. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Tuesday 6/16, 1:30pm-3:00pm (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)====

This session will focus on reconnection in the magnetotail and its effects on the inner magnetosphere. In particular, a topic that has generated a lot of interest of late are the kinetic processes associated with energy conversion and the formation and consequences of dipolarization fronts. We also encourage discussion on reconnection onset in the magnetotail - tearing vs. ballooning/interchange. Other relevant topics are welcome.

====Wednesday 6/17, 3:30pm-5:00pm (Joint with "Metrics and Validation" Focus Group)====

The Magnetospheric Multiscale (MMS) satellites were recently launched to measure the electron dissipation region during magnetic reconnection. NASA's Community Coordinated Modeling Center (CCMC), a repository of codes and models with runs-on-request, is pursuing support of MMS science, including the implementation of particle-in-cell simulations to their portfolio. This session will include a discussion of what capabilities members of the community (modelers and observers alike) would like from CCMC for MMS science.

====Thursday 6/18, 1:30pm-3:00pm (Joint with "Geospace System Science"Focus Group)====

This session will encourage cross-focus group interaction and open ended discussion on the topic of "What is the interplay between local and global processes in regulating reconnection?" This can include local-scale (Alfven speeds, microphysics, plasma state and composition, magnetic field geometry), meso-scale (geometry of the magnetic configuration, impediment of outflows), and global-scale (magnetospheric geometry and inflation, current closure through the magnetosheath, ionospheric conductivity, ionospheric outflows). We expect observers, theorists, and modelers interested in the magnetosphere as a system will find this session interesting.

====Thursday 6/18, 3:30pm-5:00pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. We expect dayside reconnection to be a main topic of this session. We encourage discussion on topics of local vs. global control of dayside reconnection and the role of diamagnetic effects and flow shear on dayside reconnection. We encourage people interested in opening a discussion on a topic (the ones listed or otherwise) to attend. Please email Paul.Cassak at mail.wvu.edu by June 9 if you would like to propose a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions, and see you in Snowmass.

===2014 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the
Magnetosphere" Focus Group sessions at the upcoming GEM Meeting.

The format for each is to have two speakers set the scene on a
particular topic. Others are encouraged to contribute to the
discussion and put up a slide or two as relevant. Half of one session
will be for general contributions consisting of no more than 4 slides
- 1 for intro to acclimate graduate students, and no more than 3 on
your topic. If you would like to be considered for one of the general
contributions, please email Paul.Cassak at mail.wvu.edu with your
topic. We will try to accommodate as many of the requests for talks
as possible. We strongly encourage everyone wishing to present to
sign up to give a poster to ensure you are able to present more than a
few slides. Please let one of the focus group chairs know if you have
any comments or questions.

The dates, times, locations, and summaries for each session are
described here:

====Monday 6/16, 10:30am-12:15pm, Ports Ballroom I-III====
First half - "What controls the rate of dayside reconnection?"
Scene-setters - Joe Borovsky and Ramon Lopez
Science - It has long been thought that the reconnection rate at the
dayside is controlled by the electric field in the solar wind. Recent
observations that geomagnetic indices are affected by plasmaspheric
drainage plumes called this into question, suggesting local control of
the reconnection rate. This session will tackle this fundamental
question of importance to solar wind-magnetospheric coupling. We will
hear from proponents on each side and discuss how future progress will
be made on these questions.

Second half - "General Contributions"
Scene-setters - None
Science - Please consider contributing a few slides on any topic on
reconnection (provided it is GEM relevant). Observations, modeling,
and theory presentations are encouraged. Again, since we are only
leaving 45 minutes for this session, all potential contributors are
encouraged to also sign up to give a poster.

====Monday 6/16, 1:30pm-3:00pm, Ports Ballroom I-III====
First half - "What determines the cross-tail scale of reconnection
jets?"
Scene-setters - Phil Pritchett and Jiang Liu
Science - Multi-satellite missions have made it accessible to study
the three-dimensional structure of reconnection in the
magnetotail. Observationally, what is the characteristic length in
the out-of-plane direction of the reconnection events? Theoretically,
what physically sets this length? These topics will be discussed in
this session.

Second half - "How is magnetotail reconnection modulated by dayside
reconnection? What is the nature of magnetotail reconnection onset
and transients?"
Scene-setters - Toshi Nishimura and Joachim Birn
Science - Reconnection in the magnetotail onsets abruptly, and is

====Abstract====
Magnetic reconnection underlies the dynamics in many aspects of magnetospheric
physics and is critical to the development of a predictive understanding of space weather
phenomena. It importance spans from the dayside where solar wind-magnetospheric coupling
occurs to the nightside where storm and substorm phenomena occur. Many existing Focus
Groups treat reconnection in the context of a particular application, but a Focus Group
specifically on reconnection is being proposed to develop an understanding that could not be
attained from studies on particular applications. Broadly, the proposed Focus Group will
address kinetic physics of reconnection and how it couples to macroscales, reconnection at the
dayside and its relation to solar wind-magnetospheric coupling, three-dimensional reconnection,
reconnection onset and transient behavior and implications for transport, and particle
acceleration in reconnection. The proposed Focus Group is timely as simulations have matured
to the point where they can offer realistic comparisons to observations, and the existing
THEMIS/ARTEMIS and upcoming MMS missions include reconnection physics as a key feature
of their goals. Reconnection is by nature cross-disciplinary and offers many opportunities for
interaction with existing Focus Groups. The proposed reconnection Focus Group is for five
years, and will produce deliverables of import for many aspects of GEM goals.

==== Topic Description ====

During magnetic reconnection, a change in magnetic topology facilitates the conversion
of magnetic energy to kinetic and thermal energy and allows mixing of plasmas on either side of
current sheets. It is the driver of many dynamical behaviors in the magnetosphere that are of
crucial importance to space weather. At the dayside magnetopause, reconnection plays a
critical role in solar wind-magnetospheric coupling and recent evidence suggests it may even
control the coupling efficiency. This process is the driver of magnetospheric convection,
evolution of the radiation belts, and loading of energy in the magnetotail. The release of this
energy in geomagnetic storms and substorms is a result of reconnection in the magnetotail.
Reconnection also produces energetic particles that can damage satellites. At present,
magnetic reconnection is studied separately under the auspices of particular applications within
separate GEM Focus Groups. The proposed Focus Group will address the physics of
reconnection as a distinct physical process which is important for magnetospheric applications
in ways that cannot be addressed in applied settings. There is a long history of success in GEM
on reconnection (including the highly-cited GEM Reconnection Challenge). The proposed
Focus Group will foster interaction between observations, simulations, and models. The broad
goals of the Reconnection Focus Group are to contribute to the understanding of (1) the kinetic
microphysics of reconnection and how it couples to the magnetosphere at macroscales, (2) how
and where dayside reconnection occurs and how it contributes to solar wind-magnetospheric
coupling including the role of flux transfer events, (3) how three-dimensional reconnection
proceeds, especially at the dayside, (4) the onset of reconnection and the physics of transient
reconnection events and their relation to bursty bulk flows, dipolarization fronts, and entropy
bubbles, and (5) how reconnection produces energetic particles. Recent advances in fluid and
kinetic simulations both locally at reconnection sites and globally containing the whole
magnetosphere have led to a point where realistic numerical models can be compared directly
with satellite observations. The Focus Group will benefit from a wealth of observational data
from existing satellites, as well as new highly resolved multi-point observational data from the
THEMIS/ARTEMIS mission and the upcoming Magnetospheric MultiScale (MMS) mission.
Strong ties with existing Focus Groups studying applications of reconnection will be made.

==== Timeliness of the Focus Group ====

A GEM Focus Group on magnetic reconnection is particularly timely. NASAs
Magnetospheric MultiScale (MMS) Mission, with a planned launch date of October of 2014,
"will use Earth's magnetosphere as a laboratory to study magnetic reconnection" (http://
mms.gsfc.nasa.gov/about_mms.html), focussing on the kinetic-scale microphysics. This
requires spacecraft to be closer together than previous missions and will provide unprecedented
observational resolution. The three-probe THEMIS constellation will also be reconfigured to
form a larger scale tetrahedron with MMS at one node to provide the macroscopic context for
the microscopic measurements by MMS. In addition, the ARTEMIS satellites repurposed from
the THEMIS mission have recently moved into a lunar orbit and will provide information on the
mid-tail region where reconnection is expected to occur and serve as a solar wind monitor on
the dayside. Therefore, near-future in-situ observations will provide measurements at a wide
scale range from the electron kinetic scale to the global scale. In the run-up to launch of MMS,
a GEM Focus Group on reconnection emphasizing numerical and observational studies will play
a central role in preparing for the mission by investigating what signals should be expected and
in what locations of the magnetosphere. After the launch of MMS, the GEM Focus Group will be
an avenue for analyzing and interpreting the data with comparisons to simulations and for
putting the newly obtained knowledge in context of larger-scale magnetospheric behavior.

==== Relation to Existing GEM Focus Groups ====

As magnetic reconnection underlies dynamics in every GEM Research Area, this Focus
Group has enormous potential for interaction with existing Focus Groups. It is the goal of this Focus Group to both support existing efforts in other Focus Groups and to drive new avenues of research through discovery achieved in this Focus Group. A non-exhaustive discussion follows for ways in which a reconnection Focus Group is synergistic with existing Focus Groups. For each example listed, the Co-Chairs of the existing Focus Group have been contacted and agree that interdisciplinary activities with a reconnection Focus Group would be desirable.

# Plasmasphere-Magnetosphere Interactions (2008-13) - The PMI Focus Group is an example where previous incarnations of reconnection studies at GEM have successfully had interdisciplinary activities. The previous reconnection focus group produced studies on asymmetric reconnection and how it may occur at the dayside magnetosphere. Recent studies showed that solar wind-magnetospheric coupling is less efficient when high density plasmaspheric drainage plumes reach the dayside reconnection site. This is consistent with reconnection becoming less efficient when asymmetric reconnection occurs with high density plasma. A presentation on this was given in a PMI session. Though the PMI Focus Group will end soon, it is expected that the previous interdisciplinary activities will continue.
# Substorm Expansion Onset: The First 10 Minutes (2008-13) - This is another example where there has been cross-participation in the past. The physics of dipolarization fronts and how they can be used to understand reconnection onset in substorms is common to both groups, as it was recently determined that they occur at the onset of reconnection. Kinetic simulations have been very useful to understand their properties.
# Magnetosheath (2010-14) - The magnetosheath is strongly linked to dayside reconnection physics. Many issues of the structure of the magnetosheath are related to how reconnection proceeds, such as the appearance or lack of flux pile-up at the magnetopause and the propensity for flux transfer events. Understanding how kinetic effects impact dayside reconnection and the march to global kinetic modeling, and where reconnection at the dayside occurs as a function of solar wind conditions, are both synergistic topics.
# Metrics and Validation (2011-15) - This group addresses challenges of model-data comparisons and how to assess them. In the past, a barrier to performing careful metrics and validation studies of magnetic reconnection has been a lack of sufficient observations, but the MMS mission is expected to change this. Therefore, a potential avenue for collaboration with the Metrics and Validation Focus Group is comparisons of kinetic modeling and observational data from MMS.
# Tail-Inner Magnetosphere Interactions (2012-16) - This Focus Group addresses modes of transport that cause heating in the magnetotail and inner magnetosphere. It is thought that transient events such as bursty bulk flows, entropy bubbles, and dipolarization fronts play a potentially important role. As these events are associated with magnetotail reconnection, there is strong potential for cross-disciplinary interactions with this Focus Group.

====Goals and Deliverables====

The goals of the Reconnection Focus Group are to understand aspects of
magnetospheric reconnection with an eye to applications in other Focus Groups. This list is not
exhaustive, but it has been compiled using input from the GEM community.

# What is the physics of reconnection at the kinetic scale and how does it couple to the magnetosphere at macro-scales? Particular topics include the role of the extended electron diffusion region, pressure anisotropies, normal magnetic fields for magnetotail applications, asymmetries in density and magnetic field, and whether or how the microphysics of reconnection can be incorporated into fluid models in geospace general circulation models (GGCMs). Examples of deliverables for simulation and modeling work include answers to the following questions - What sets the scale of the extended electron diffusion region and what is its effect on reconnection? (This will be important both before and after the launch of MMS for locating and analyzing reconnection events.) How do asymmetries effect the kinetic signatures of reconnection? Under what conditions do pressure anisotropies arise? Observational deliverables include THEMIS/ARTEMIS and MMS results, which will be compared to numerical simulations.
# How does reconnection proceed at the dayside and how does it contribute to solar wind-magnetospheric coupling? Topics include the role of asymmetries and shear flow in setting the efficiency of reconnection and the role of flux transfer events. Deliverables include quantitative predictions of dayside reconnection efficiency as a function of solar wind conditions that can be fed into solar wind-magnetospheric coupling functions as in the Borovsky coupling function and expected properties of flux transfer events in kinetic simulations and observations.
# How does three-dimensional reconnection proceed, especially at the dayside? Numerical deliverables include answering these questions - What is the location of reconnection on the dayside and its efficiency as a function of solar wind conditions? What differences are there between in 2D and fully 3D reconnection? Observational deliverables include signatures of the dissipation region in fully 3D settings and their meso- and macro-scale ramifications.
# How does reconnection onset and what is the physics of transient reconnection events such as bursty bulk flows, dipolarization fronts, entropy bubbles, and flux transfer events? Deliverables include how their properties depend on magnetospheric conditions, their role in energy and mass transport, how they expand and spread as a function of time, and comparisons with observational data from the THEMIS/ARTEMIS mission.
# How are energetic particles produced during reconnection? This includes mechanisms based on reconnection electric fields and secondary islands. Deliverables include the relative importance of various particle acceleration mechanisms and the observational signatures that result, and observations of these events from THEMIS/ARTEMIS and MMS.

===2016 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop.

We have a broad collection of sessions planned for this year, including both basic reconnection science and joint sessions with focus groups where reconnection plays a role in the broader dynamics. The sessions are intended to be driven by open discussion, but attendees are encouraged to enhance the discussion by showing a slide or two as appropriate. As in the past, we are asking participants to not do AGU-style presentations. As always, we will try to accommodate all who want to speak, but the priority is having open and active discussion over sticking to a schedule. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Monday 6/20, PM1 - 1:30pm-3:30pm (Individual session)====

This session will focus on kinetic physics in day- and night-side reconnection. With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). We also encourage discussion on other relevant topics. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you are interested in being part of the discussion.

====Monday 6/20, PM2 - 4:00pm-6:00pm (Joint with Mesoscale Auroral and Polar Cap Dynamics and Substorms focus groups)====

We will discuss the following topics:

-- Ionospheric signatures of magnetopause reconnection and FTEs

-- Possible dayside-nightside coupling (remote observations, modeling, tests for in-situ multi-point observations)

-- The role of the ionosphere in transient day- and night-side reconnection-related processes

Contributions from ground- and space-based observers as well as from modelers are welcome. Please contact Brian Walsh <bwalsh at bu.edu> if you are interested in being part of the discussion.

====Tuesday 6/21, PM1 - 1:30pm-3:30pm (Joint with Dayside Kinetic and Transient Phenomena focus groups)====

This session will encourage cross-focus group interaction and open ended discussion on the topics of magnetopause reconnection, flux-transfer events, Kelvin-Helmholtz instability, magnetopause waves, and other boundary layer processes. Talks on MMS-related studies and modeling with the emphasis on global magnetospheric aspects of reconnection are especially encouraged. Please contact Yi-Hsin Liu <yi-hsin.liu at nasa.gov> by Friday, June 10 if you are interested in being part of the discussion.

====Friday 6/24, PM1 - 1:30pm-3:30pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any of the earlier sessions as interest dictates. In addition, there will be an update on efforts to incorporate kinetic modeling into NASA’s CCMC. We also hope there is time for a discussion on topics of interest for next year, and the potential future of the reconnection focus group beyond when the current version ends next year. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you would like to offer a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions.

===2015 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting. We also welcome Yi-Hsin Liu and Brian Walsh to our team of co-chairs, and offer thanks to Homa Karimabadi for his years of service.

Last year, we employed two "scene setting" talks per session to frame relevant questions and generate discussion for the remainder of the session. We intend to use a similar strategy this year. We are in the process of lining up speakers, but if you would like to nominate someone (including a self-nomination) for any of the sessions listed below, please email Paul.Cassak at mail.wvu.edu with the name(s) and a brief justification.

Others are encouraged to enhance the discussion by showing a slide or two as appropriate, and we expect some time for open discussion. As in the past, we are asking participants to not do AGU-style presentations, opting for discussion and real-time progress instead. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Tuesday 6/16, 1:30pm-3:00pm (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)====

This session will focus on reconnection in the magnetotail and its effects on the inner magnetosphere. In particular, a topic that has generated a lot of interest of late are the kinetic processes associated with energy conversion and the formation and consequences of dipolarization fronts. We also encourage discussion on reconnection onset in the magnetotail - tearing vs. ballooning/interchange. Other relevant topics are welcome.

====Wednesday 6/17, 3:30pm-5:00pm (Joint with "Metrics and Validation" Focus Group)====

The Magnetospheric Multiscale (MMS) satellites were recently launched to measure the electron dissipation region during magnetic reconnection. NASA's Community Coordinated Modeling Center (CCMC), a repository of codes and models with runs-on-request, is pursuing support of MMS science, including the implementation of particle-in-cell simulations to their portfolio. This session will include a discussion of what capabilities members of the community (modelers and observers alike) would like from CCMC for MMS science.

====Thursday 6/18, 1:30pm-3:00pm (Joint with "Geospace System Science"Focus Group)====

This session will encourage cross-focus group interaction and open ended discussion on the topic of "What is the interplay between local and global processes in regulating reconnection?" This can include local-scale (Alfven speeds, microphysics, plasma state and composition, magnetic field geometry), meso-scale (geometry of the magnetic configuration, impediment of outflows), and global-scale (magnetospheric geometry and inflation, current closure through the magnetosheath, ionospheric conductivity, ionospheric outflows). We expect observers, theorists, and modelers interested in the magnetosphere as a system will find this session interesting.

====Thursday 6/18, 3:30pm-5:00pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. We expect dayside reconnection to be a main topic of this session. We encourage discussion on topics of local vs. global control of dayside reconnection and the role of diamagnetic effects and flow shear on dayside reconnection. We encourage people interested in opening a discussion on a topic (the ones listed or otherwise) to attend. Please email Paul.Cassak at mail.wvu.edu by June 9 if you would like to propose a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions, and see you in Snowmass.

===2014 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the
Magnetosphere" Focus Group sessions at the upcoming GEM Meeting.

The format for each is to have two speakers set the scene on a
particular topic. Others are encouraged to contribute to the
discussion and put up a slide or two as relevant. Half of one session
will be for general contributions consisting of no more than 4 slides
- 1 for intro to acclimate graduate students, and no more than 3 on
your topic. If you would like to be considered for one of the general
contributions, please email Paul.Cassak at mail.wvu.edu with your
topic. We will try to accommodate as many of the requests for talks
as possible. We strongly encourage everyone wishing to present to
sign up to give a poster to ensure you are able to present more than a
few slides. Please let one of the focus group chairs know if you have
any comments or questions.

The dates, times, locations, and summaries for each session are
described here:

====Monday 6/16, 10:30am-12:15pm, Ports Ballroom I-III====
First half - "What controls the rate of dayside reconnection?"
Scene-setters - Joe Borovsky and Ramon Lopez
Science - It has long been thought that the reconnection rate at the
dayside is controlled by the electric field in the solar wind. Recent
observations that geomagnetic indices are affected by plasmaspheric
drainage plumes called this into question, suggesting local control of
the reconnection rate. This session will tackle this fundamental
question of importance to solar wind-magnetospheric coupling. We will
hear from proponents on each side and discuss how future progress will
be made on these questions.

Second half - "General Contributions"
Scene-setters - None
Science - Please consider contributing a few slides on any topic on
reconnection (provided it is GEM relevant). Observations, modeling,
and theory presentations are encouraged. Again, since we are only
leaving 45 minutes for this session, all potential contributors are
encouraged to also sign up to give a poster.

====Monday 6/16, 1:30pm-3:00pm, Ports Ballroom I-III====
First half - "What determines the cross-tail scale of reconnection
jets?"
Scene-setters - Phil Pritchett and Jiang Liu
Science - Multi-satellite missions have made it accessible to study
the three-dimensional structure of reconnection in the
magnetotail. Observationally, what is the characteristic length in
the out-of-plane direction of the reconnection events? Theoretically,
what physically sets this length? These topics will be discussed in
this session.

Second half - "How is magnetotail reconnection modulated by dayside
reconnection? What is the nature of magnetotail reconnection onset
and transients?"
Scene-setters - Toshi Nishimura and Joachim Birn
Science - Reconnection in the magnetotail onsets abruptly, and is
often bursty. It can further be modulated due to time-dependent
phenomena on the dayside. This session will discuss how reconnection
in the magnetotail responds to modulation from the dayside and what
causes reconnection onset and transients in the
magnetotail. Observational and theoretical/modeling considerations
will be discussed.

====Monday 6/16, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)=====
Scene-setters - Misha Sitnov and Andrei Runov
Science - This joint session will focus on the relationship between
bursty bulk flows/dipolarization fronts and reconnection, both from
the observational and theoretical/modeling perspective. In many ways,
this is a continuation of the1:30-3:00 session, but additional
attention will be paid to
the ramifications on the inner magnetosphere.
Please let Paul.Cassak at mail.wvu.edu or toffo atrice.edu know if you
are interested in contributing.

====Thursday 6/19, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "The Magnetosheath" Focus Group)=====
Scene-setters - TBD
Science - We seek observational and theory/simulation speakers who
study
1. the consequences of foreshock and magnetosheath turbulence on
dayside reconnection,
2. the effects of velocity shear and plasma beta on dayside
reconnection,
3. plasma heating in magnetosheath reconnection.
Please send your contribution ideas to session organizers by the 6th
of June(any of the above organizers or petrinec at lmsal.com or
nykyrik at erau.edu)

We look forward to seeing you at the sessions! Please let the
organizers (Paul.Cassak at mail.wvu.edu) know about contributions
by Friday, June 6.

====Abstract====
Magnetic reconnection underlies the dynamics in many aspects of magnetospheric
physics and is critical to the development of a predictive understanding of space weather
phenomena. It importance spans from the dayside where solar wind-magnetospheric coupling
occurs to the nightside where storm and substorm phenomena occur. Many existing Focus
Groups treat reconnection in the context of a particular application, but a Focus Group
specifically on reconnection is being proposed to develop an understanding that could not be
attained from studies on particular applications. Broadly, the proposed Focus Group will
address kinetic physics of reconnection and how it couples to macroscales, reconnection at the
dayside and its relation to solar wind-magnetospheric coupling, three-dimensional reconnection,
reconnection onset and transient behavior and implications for transport, and particle
acceleration in reconnection. The proposed Focus Group is timely as simulations have matured
to the point where they can offer realistic comparisons to observations, and the existing
THEMIS/ARTEMIS and upcoming MMS missions include reconnection physics as a key feature
of their goals. Reconnection is by nature cross-disciplinary and offers many opportunities for
interaction with existing Focus Groups. The proposed reconnection Focus Group is for five
years, and will produce deliverables of import for many aspects of GEM goals.

==== Topic Description ====

During magnetic reconnection, a change in magnetic topology facilitates the conversion
of magnetic energy to kinetic and thermal energy and allows mixing of plasmas on either side of
current sheets. It is the driver of many dynamical behaviors in the magnetosphere that are of
crucial importance to space weather. At the dayside magnetopause, reconnection plays a
critical role in solar wind-magnetospheric coupling and recent evidence suggests it may even
control the coupling efficiency. This process is the driver of magnetospheric convection,
evolution of the radiation belts, and loading of energy in the magnetotail. The release of this
energy in geomagnetic storms and substorms is a result of reconnection in the magnetotail.
Reconnection also produces energetic particles that can damage satellites. At present,
magnetic reconnection is studied separately under the auspices of particular applications within
separate GEM Focus Groups. The proposed Focus Group will address the physics of
reconnection as a distinct physical process which is important for magnetospheric applications
in ways that cannot be addressed in applied settings. There is a long history of success in GEM
on reconnection (including the highly-cited GEM Reconnection Challenge). The proposed
Focus Group will foster interaction between observations, simulations, and models. The broad
goals of the Reconnection Focus Group are to contribute to the understanding of (1) the kinetic
microphysics of reconnection and how it couples to the magnetosphere at macroscales, (2) how
and where dayside reconnection occurs and how it contributes to solar wind-magnetospheric
coupling including the role of flux transfer events, (3) how three-dimensional reconnection
proceeds, especially at the dayside, (4) the onset of reconnection and the physics of transient
reconnection events and their relation to bursty bulk flows, dipolarization fronts, and entropy
bubbles, and (5) how reconnection produces energetic particles. Recent advances in fluid and
kinetic simulations both locally at reconnection sites and globally containing the whole
magnetosphere have led to a point where realistic numerical models can be compared directly
with satellite observations. The Focus Group will benefit from a wealth of observational data
from existing satellites, as well as new highly resolved multi-point observational data from the
THEMIS/ARTEMIS mission and the upcoming Magnetospheric MultiScale (MMS) mission.
Strong ties with existing Focus Groups studying applications of reconnection will be made.

==== Timeliness of the Focus Group ====

A GEM Focus Group on magnetic reconnection is particularly timely. NASAs
Magnetospheric MultiScale (MMS) Mission, with a planned launch date of October of 2014,
"will use Earth's magnetosphere as a laboratory to study magnetic reconnection" (http://
mms.gsfc.nasa.gov/about_mms.html), focussing on the kinetic-scale microphysics. This
requires spacecraft to be closer together than previous missions and will provide unprecedented
observational resolution. The three-probe THEMIS constellation will also be reconfigured to
form a larger scale tetrahedron with MMS at one node to provide the macroscopic context for
the microscopic measurements by MMS. In addition, the ARTEMIS satellites repurposed from
the THEMIS mission have recently moved into a lunar orbit and will provide information on the
mid-tail region where reconnection is expected to occur and serve as a solar wind monitor on
the dayside. Therefore, near-future in-situ observations will provide measurements at a wide
scale range from the electron kinetic scale to the global scale. In the run-up to launch of MMS,
a GEM Focus Group on reconnection emphasizing numerical and observational studies will play
a central role in preparing for the mission by investigating what signals should be expected and
in what locations of the magnetosphere. After the launch of MMS, the GEM Focus Group will be
an avenue for analyzing and interpreting the data with comparisons to simulations and for
putting the newly obtained knowledge in context of larger-scale magnetospheric behavior.

==== Relation to Existing GEM Focus Groups ====

As magnetic reconnection underlies dynamics in every GEM Research Area, this Focus
Group has enormous potential for interaction with existing Focus Groups. It is the goal of this Focus Group to both support existing efforts in other Focus Groups and to drive new avenues of research through discovery achieved in this Focus Group. A non-exhaustive discussion follows for ways in which a reconnection Focus Group is synergistic with existing Focus Groups. For each example listed, the Co-Chairs of the existing Focus Group have been contacted and agree that interdisciplinary activities with a reconnection Focus Group would be desirable.

# Plasmasphere-Magnetosphere Interactions (2008-13) - The PMI Focus Group is an example where previous incarnations of reconnection studies at GEM have successfully had interdisciplinary activities. The previous reconnection focus group produced studies on asymmetric reconnection and how it may occur at the dayside magnetosphere. Recent studies showed that solar wind-magnetospheric coupling is less efficient when high density plasmaspheric drainage plumes reach the dayside reconnection site. This is consistent with reconnection becoming less efficient when asymmetric reconnection occurs with high density plasma. A presentation on this was given in a PMI session. Though the PMI Focus Group will end soon, it is expected that the previous interdisciplinary activities will continue.
# Substorm Expansion Onset: The First 10 Minutes (2008-13) - This is another example where there has been cross-participation in the past. The physics of dipolarization fronts and how they can be used to understand reconnection onset in substorms is common to both groups, as it was recently determined that they occur at the onset of reconnection. Kinetic simulations have been very useful to understand their properties.
# Magnetosheath (2010-14) - The magnetosheath is strongly linked to dayside reconnection physics. Many issues of the structure of the magnetosheath are related to how reconnection proceeds, such as the appearance or lack of flux pile-up at the magnetopause and the propensity for flux transfer events. Understanding how kinetic effects impact dayside reconnection and the march to global kinetic modeling, and where reconnection at the dayside occurs as a function of solar wind conditions, are both synergistic topics.
# Metrics and Validation (2011-15) - This group addresses challenges of model-data comparisons and how to assess them. In the past, a barrier to performing careful metrics and validation studies of magnetic reconnection has been a lack of sufficient observations, but the MMS mission is expected to change this. Therefore, a potential avenue for collaboration with the Metrics and Validation Focus Group is comparisons of kinetic modeling and observational data from MMS.
# Tail-Inner Magnetosphere Interactions (2012-16) - This Focus Group addresses modes of transport that cause heating in the magnetotail and inner magnetosphere. It is thought that transient events such as bursty bulk flows, entropy bubbles, and dipolarization fronts play a potentially important role. As these events are associated with magnetotail reconnection, there is strong potential for cross-disciplinary interactions with this Focus Group.

====Goals and Deliverables====

The goals of the Reconnection Focus Group are to understand aspects of
magnetospheric reconnection with an eye to applications in other Focus Groups. This list is not
exhaustive, but it has been compiled using input from the GEM community.

# What is the physics of reconnection at the kinetic scale and how does it couple to the magnetosphere at macro-scales? Particular topics include the role of the extended electron diffusion region, pressure anisotropies, normal magnetic fields for magnetotail applications, asymmetries in density and magnetic field, and whether or how the microphysics of reconnection can be incorporated into fluid models in geospace general circulation models (GGCMs). Examples of deliverables for simulation and modeling work include answers to the following questions - What sets the scale of the extended electron diffusion region and what is its effect on reconnection? (This will be important both before and after the launch of MMS for locating and analyzing reconnection events.) How do asymmetries effect the kinetic signatures of reconnection? Under what conditions do pressure anisotropies arise? Observational deliverables include THEMIS/ARTEMIS and MMS results, which will be compared to numerical simulations.
# How does reconnection proceed at the dayside and how does it contribute to solar wind-magnetospheric coupling? Topics include the role of asymmetries and shear flow in setting the efficiency of reconnection and the role of flux transfer events. Deliverables include quantitative predictions of dayside reconnection efficiency as a function of solar wind conditions that can be fed into solar wind-magnetospheric coupling functions as in the Borovsky coupling function and expected properties of flux transfer events in kinetic simulations and observations.
# How does three-dimensional reconnection proceed, especially at the dayside? Numerical deliverables include answering these questions - What is the location of reconnection on the dayside and its efficiency as a function of solar wind conditions? What differences are there between in 2D and fully 3D reconnection? Observational deliverables include signatures of the dissipation region in fully 3D settings and their meso- and macro-scale ramifications.
# How does reconnection onset and what is the physics of transient reconnection events such as bursty bulk flows, dipolarization fronts, entropy bubbles, and flux transfer events? Deliverables include how their properties depend on magnetospheric conditions, their role in energy and mass transport, how they expand and spread as a function of time, and comparisons with observational data from the THEMIS/ARTEMIS mission.
# How are energetic particles produced during reconnection? This includes mechanisms based on reconnection electric fields and secondary islands. Deliverables include the relative importance of various particle acceleration mechanisms and the observational signatures that result, and observations of these events from THEMIS/ARTEMIS and MMS.

===2016 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop.

We have a broad collection of sessions planned for this year, including both basic reconnection science and joint sessions with focus groups where reconnection plays a role in the broader dynamics. The sessions are intended to be driven by open discussion, but attendees are encouraged to enhance the discussion by showing a slide or two as appropriate. As in the past, we are asking participants to not do AGU-style presentations. As always, we will try to accommodate all who want to speak, but the priority is having open and active discussion over sticking to a schedule. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Monday 6/20, PM1 - 1:30pm-3:30pm (Individual session)====

This session will focus on kinetic physics in day- and night-side reconnection. With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). We also encourage discussion on other relevant topics. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you are interested in being part of the discussion.

====Monday 6/20, PM2 - 4:00pm-6:00pm (Joint with Mesoscale Auroral and Polar Cap Dynamics and Substorms focus groups)====

We will discuss the following topics:

-- Ionospheric signatures of magnetopause reconnection and FTEs
-- Possible dayside-nightside coupling (remote observations, modeling, tests for in-situ multi-point observations)
-- The role of the ionosphere in transient day- and night-side reconnection-related processes

Contributions from ground- and space-based observers as well as from modelers are welcome. Please contact Brian Walsh <bwalsh at bu.edu> if you are interested in being part of the discussion.

====Tuesday 6/21, PM1 - 1:30pm-3:30pm (Joint with Dayside Kinetic and Transient Phenomena focus groups)====

This session will encourage cross-focus group interaction and open ended discussion on the topics of magnetopause reconnection, flux-transfer events, Kelvin-Helmholtz instability, magnetopause waves, and other boundary layer processes. Talks on MMS-related studies and modeling with the emphasis on global magnetospheric aspects of reconnection are especially encouraged. Please contact Yi-Hsin Liu <yi-hsin.liu at nasa.gov> by Friday, June 10 if you are interested in being part of the discussion.

====Friday 6/24, PM1 - 1:30pm-3:30pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any of the earlier sessions as interest dictates. In addition, there will be an update on efforts to incorporate kinetic modeling into NASA’s CCMC. We also hope there is time for a discussion on topics of interest for next year, and the potential future of the reconnection focus group beyond when the current version ends next year. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you would like to offer a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions.

===2015 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting. We also welcome Yi-Hsin Liu and Brian Walsh to our team of co-chairs, and offer thanks to Homa Karimabadi for his years of service.

Last year, we employed two "scene setting" talks per session to frame relevant questions and generate discussion for the remainder of the session. We intend to use a similar strategy this year. We are in the process of lining up speakers, but if you would like to nominate someone (including a self-nomination) for any of the sessions listed below, please email Paul.Cassak at mail.wvu.edu with the name(s) and a brief justification.

Others are encouraged to enhance the discussion by showing a slide or two as appropriate, and we expect some time for open discussion. As in the past, we are asking participants to not do AGU-style presentations, opting for discussion and real-time progress instead. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Tuesday 6/16, 1:30pm-3:00pm (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)====

This session will focus on reconnection in the magnetotail and its effects on the inner magnetosphere. In particular, a topic that has generated a lot of interest of late are the kinetic processes associated with energy conversion and the formation and consequences of dipolarization fronts. We also encourage discussion on reconnection onset in the magnetotail - tearing vs. ballooning/interchange. Other relevant topics are welcome.

====Wednesday 6/17, 3:30pm-5:00pm (Joint with "Metrics and Validation" Focus Group)====

The Magnetospheric Multiscale (MMS) satellites were recently launched to measure the electron dissipation region during magnetic reconnection. NASA's Community Coordinated Modeling Center (CCMC), a repository of codes and models with runs-on-request, is pursuing support of MMS science, including the implementation of particle-in-cell simulations to their portfolio. This session will include a discussion of what capabilities members of the community (modelers and observers alike) would like from CCMC for MMS science.

====Thursday 6/18, 1:30pm-3:00pm (Joint with "Geospace System Science"Focus Group)====

This session will encourage cross-focus group interaction and open ended discussion on the topic of "What is the interplay between local and global processes in regulating reconnection?" This can include local-scale (Alfven speeds, microphysics, plasma state and composition, magnetic field geometry), meso-scale (geometry of the magnetic configuration, impediment of outflows), and global-scale (magnetospheric geometry and inflation, current closure through the magnetosheath, ionospheric conductivity, ionospheric outflows). We expect observers, theorists, and modelers interested in the magnetosphere as a system will find this session interesting.

====Thursday 6/18, 3:30pm-5:00pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. We expect dayside reconnection to be a main topic of this session. We encourage discussion on topics of local vs. global control of dayside reconnection and the role of diamagnetic effects and flow shear on dayside reconnection. We encourage people interested in opening a discussion on a topic (the ones listed or otherwise) to attend. Please email Paul.Cassak at mail.wvu.edu by June 9 if you would like to propose a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions, and see you in Snowmass.

===2014 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the
Magnetosphere" Focus Group sessions at the upcoming GEM Meeting.

The format for each is to have two speakers set the scene on a
particular topic. Others are encouraged to contribute to the
discussion and put up a slide or two as relevant. Half of one session
will be for general contributions consisting of no more than 4 slides
- 1 for intro to acclimate graduate students, and no more than 3 on
your topic. If you would like to be considered for one of the general
contributions, please email Paul.Cassak at mail.wvu.edu with your
topic. We will try to accommodate as many of the requests for talks
as possible. We strongly encourage everyone wishing to present to
sign up to give a poster to ensure you are able to present more than a
few slides. Please let one of the focus group chairs know if you have
any comments or questions.

The dates, times, locations, and summaries for each session are
described here:

====Monday 6/16, 10:30am-12:15pm, Ports Ballroom I-III====
First half - "What controls the rate of dayside reconnection?"
Scene-setters - Joe Borovsky and Ramon Lopez
Science - It has long been thought that the reconnection rate at the
dayside is controlled by the electric field in the solar wind. Recent
observations that geomagnetic indices are affected by plasmaspheric
drainage plumes called this into question, suggesting local control of
the reconnection rate. This session will tackle this fundamental
question of importance to solar wind-magnetospheric coupling. We will
hear from proponents on each side and discuss how future progress will
be made on these questions.

Second half - "General Contributions"
Scene-setters - None
Science - Please consider contributing a few slides on any topic on
reconnection (provided it is GEM relevant). Observations, modeling,
and theory presentations are encouraged. Again, since we are only
leaving 45 minutes for this session, all potential contributors are
encouraged to also sign up to give a poster.

====Monday 6/16, 1:30pm-3:00pm, Ports Ballroom I-III====
First half - "What determines the cross-tail scale of reconnection
jets?"
Scene-setters - Phil Pritchett and Jiang Liu
Science - Multi-satellite missions have made it accessible to study
the three-dimensional structure of reconnection in the
magnetotail. Observationally, what is the characteristic length in
the out-of-plane direction of the reconnection events? Theoretically,
what physically sets this length? These topics will be discussed in
this session.

Second half - "How is magnetotail reconnection modulated by dayside
reconnection? What is the nature of magnetotail reconnection onset
and transients?"
Scene-setters - Toshi Nishimura and Joachim Birn
Science - Reconnection in the magnetotail onsets abruptly, and is
often bursty. It can further be modulated due to time-dependent
phenomena on the dayside. This session will discuss how reconnection
in the magnetotail responds to modulation from the dayside and what
causes reconnection onset and transients in the
magnetotail. Observational and theoretical/modeling considerations
will be discussed.

====Monday 6/16, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)=====
Scene-setters - Misha Sitnov and Andrei Runov
Science - This joint session will focus on the relationship between
bursty bulk flows/dipolarization fronts and reconnection, both from
the observational and theoretical/modeling perspective. In many ways,
this is a continuation of the1:30-3:00 session, but additional
attention will be paid to
the ramifications on the inner magnetosphere.
Please let Paul.Cassak at mail.wvu.edu or toffo atrice.edu know if you
are interested in contributing.

====Thursday 6/19, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "The Magnetosheath" Focus Group)=====
Scene-setters - TBD
Science - We seek observational and theory/simulation speakers who
study
1. the consequences of foreshock and magnetosheath turbulence on
dayside reconnection,
2. the effects of velocity shear and plasma beta on dayside
reconnection,
3. plasma heating in magnetosheath reconnection.
Please send your contribution ideas to session organizers by the 6th
of June(any of the above organizers or petrinec at lmsal.com or
nykyrik at erau.edu)

We look forward to seeing you at the sessions! Please let the
organizers (Paul.Cassak at mail.wvu.edu) know about contributions

====Abstract====
Magnetic reconnection underlies the dynamics in many aspects of magnetospheric
physics and is critical to the development of a predictive understanding of space weather
phenomena. It importance spans from the dayside where solar wind-magnetospheric coupling
occurs to the nightside where storm and substorm phenomena occur. Many existing Focus
Groups treat reconnection in the context of a particular application, but a Focus Group
specifically on reconnection is being proposed to develop an understanding that could not be
attained from studies on particular applications. Broadly, the proposed Focus Group will
address kinetic physics of reconnection and how it couples to macroscales, reconnection at the
dayside and its relation to solar wind-magnetospheric coupling, three-dimensional reconnection,
reconnection onset and transient behavior and implications for transport, and particle
acceleration in reconnection. The proposed Focus Group is timely as simulations have matured
to the point where they can offer realistic comparisons to observations, and the existing
THEMIS/ARTEMIS and upcoming MMS missions include reconnection physics as a key feature
of their goals. Reconnection is by nature cross-disciplinary and offers many opportunities for
interaction with existing Focus Groups. The proposed reconnection Focus Group is for five
years, and will produce deliverables of import for many aspects of GEM goals.

==== Topic Description ====

During magnetic reconnection, a change in magnetic topology facilitates the conversion
of magnetic energy to kinetic and thermal energy and allows mixing of plasmas on either side of
current sheets. It is the driver of many dynamical behaviors in the magnetosphere that are of
crucial importance to space weather. At the dayside magnetopause, reconnection plays a
critical role in solar wind-magnetospheric coupling and recent evidence suggests it may even
control the coupling efficiency. This process is the driver of magnetospheric convection,
evolution of the radiation belts, and loading of energy in the magnetotail. The release of this
energy in geomagnetic storms and substorms is a result of reconnection in the magnetotail.
Reconnection also produces energetic particles that can damage satellites. At present,
magnetic reconnection is studied separately under the auspices of particular applications within
separate GEM Focus Groups. The proposed Focus Group will address the physics of
reconnection as a distinct physical process which is important for magnetospheric applications
in ways that cannot be addressed in applied settings. There is a long history of success in GEM
on reconnection (including the highly-cited GEM Reconnection Challenge). The proposed
Focus Group will foster interaction between observations, simulations, and models. The broad
goals of the Reconnection Focus Group are to contribute to the understanding of (1) the kinetic
microphysics of reconnection and how it couples to the magnetosphere at macroscales, (2) how
and where dayside reconnection occurs and how it contributes to solar wind-magnetospheric
coupling including the role of flux transfer events, (3) how three-dimensional reconnection
proceeds, especially at the dayside, (4) the onset of reconnection and the physics of transient
reconnection events and their relation to bursty bulk flows, dipolarization fronts, and entropy
bubbles, and (5) how reconnection produces energetic particles. Recent advances in fluid and
kinetic simulations both locally at reconnection sites and globally containing the whole
magnetosphere have led to a point where realistic numerical models can be compared directly
with satellite observations. The Focus Group will benefit from a wealth of observational data
from existing satellites, as well as new highly resolved multi-point observational data from the
THEMIS/ARTEMIS mission and the upcoming Magnetospheric MultiScale (MMS) mission.
Strong ties with existing Focus Groups studying applications of reconnection will be made.

==== Timeliness of the Focus Group ====

A GEM Focus Group on magnetic reconnection is particularly timely. NASAs
Magnetospheric MultiScale (MMS) Mission, with a planned launch date of October of 2014,
"will use Earth's magnetosphere as a laboratory to study magnetic reconnection" (http://
mms.gsfc.nasa.gov/about_mms.html), focussing on the kinetic-scale microphysics. This
requires spacecraft to be closer together than previous missions and will provide unprecedented
observational resolution. The three-probe THEMIS constellation will also be reconfigured to
form a larger scale tetrahedron with MMS at one node to provide the macroscopic context for
the microscopic measurements by MMS. In addition, the ARTEMIS satellites repurposed from
the THEMIS mission have recently moved into a lunar orbit and will provide information on the
mid-tail region where reconnection is expected to occur and serve as a solar wind monitor on
the dayside. Therefore, near-future in-situ observations will provide measurements at a wide
scale range from the electron kinetic scale to the global scale. In the run-up to launch of MMS,
a GEM Focus Group on reconnection emphasizing numerical and observational studies will play
a central role in preparing for the mission by investigating what signals should be expected and
in what locations of the magnetosphere. After the launch of MMS, the GEM Focus Group will be
an avenue for analyzing and interpreting the data with comparisons to simulations and for
putting the newly obtained knowledge in context of larger-scale magnetospheric behavior.

==== Relation to Existing GEM Focus Groups ====

As magnetic reconnection underlies dynamics in every GEM Research Area, this Focus
Group has enormous potential for interaction with existing Focus Groups. It is the goal of this Focus Group to both support existing efforts in other Focus Groups and to drive new avenues of research through discovery achieved in this Focus Group. A non-exhaustive discussion follows for ways in which a reconnection Focus Group is synergistic with existing Focus Groups. For each example listed, the Co-Chairs of the existing Focus Group have been contacted and agree that interdisciplinary activities with a reconnection Focus Group would be desirable.

# Plasmasphere-Magnetosphere Interactions (2008-13) - The PMI Focus Group is an example where previous incarnations of reconnection studies at GEM have successfully had interdisciplinary activities. The previous reconnection focus group produced studies on asymmetric reconnection and how it may occur at the dayside magnetosphere. Recent studies showed that solar wind-magnetospheric coupling is less efficient when high density plasmaspheric drainage plumes reach the dayside reconnection site. This is consistent with reconnection becoming less efficient when asymmetric reconnection occurs with high density plasma. A presentation on this was given in a PMI session. Though the PMI Focus Group will end soon, it is expected that the previous interdisciplinary activities will continue.
# Substorm Expansion Onset: The First 10 Minutes (2008-13) - This is another example where there has been cross-participation in the past. The physics of dipolarization fronts and how they can be used to understand reconnection onset in substorms is common to both groups, as it was recently determined that they occur at the onset of reconnection. Kinetic simulations have been very useful to understand their properties.
# Magnetosheath (2010-14) - The magnetosheath is strongly linked to dayside reconnection physics. Many issues of the structure of the magnetosheath are related to how reconnection proceeds, such as the appearance or lack of flux pile-up at the magnetopause and the propensity for flux transfer events. Understanding how kinetic effects impact dayside reconnection and the march to global kinetic modeling, and where reconnection at the dayside occurs as a function of solar wind conditions, are both synergistic topics.
# Metrics and Validation (2011-15) - This group addresses challenges of model-data comparisons and how to assess them. In the past, a barrier to performing careful metrics and validation studies of magnetic reconnection has been a lack of sufficient observations, but the MMS mission is expected to change this. Therefore, a potential avenue for collaboration with the Metrics and Validation Focus Group is comparisons of kinetic modeling and observational data from MMS.
# Tail-Inner Magnetosphere Interactions (2012-16) - This Focus Group addresses modes of transport that cause heating in the magnetotail and inner magnetosphere. It is thought that transient events such as bursty bulk flows, entropy bubbles, and dipolarization fronts play a potentially important role. As these events are associated with magnetotail reconnection, there is strong potential for cross-disciplinary interactions with this Focus Group.

====Goals and Deliverables====

The goals of the Reconnection Focus Group are to understand aspects of
magnetospheric reconnection with an eye to applications in other Focus Groups. This list is not
exhaustive, but it has been compiled using input from the GEM community.

# What is the physics of reconnection at the kinetic scale and how does it couple to the magnetosphere at macro-scales? Particular topics include the role of the extended electron diffusion region, pressure anisotropies, normal magnetic fields for magnetotail applications, asymmetries in density and magnetic field, and whether or how the microphysics of reconnection can be incorporated into fluid models in geospace general circulation models (GGCMs). Examples of deliverables for simulation and modeling work include answers to the following questions - What sets the scale of the extended electron diffusion region and what is its effect on reconnection? (This will be important both before and after the launch of MMS for locating and analyzing reconnection events.) How do asymmetries effect the kinetic signatures of reconnection? Under what conditions do pressure anisotropies arise? Observational deliverables include THEMIS/ARTEMIS and MMS results, which will be compared to numerical simulations.
# How does reconnection proceed at the dayside and how does it contribute to solar wind-magnetospheric coupling? Topics include the role of asymmetries and shear flow in setting the efficiency of reconnection and the role of flux transfer events. Deliverables include quantitative predictions of dayside reconnection efficiency as a function of solar wind conditions that can be fed into solar wind-magnetospheric coupling functions as in the Borovsky coupling function and expected properties of flux transfer events in kinetic simulations and observations.
# How does three-dimensional reconnection proceed, especially at the dayside? Numerical deliverables include answering these questions - What is the location of reconnection on the dayside and its efficiency as a function of solar wind conditions? What differences are there between in 2D and fully 3D reconnection? Observational deliverables include signatures of the dissipation region in fully 3D settings and their meso- and macro-scale ramifications.
# How does reconnection onset and what is the physics of transient reconnection events such as bursty bulk flows, dipolarization fronts, entropy bubbles, and flux transfer events? Deliverables include how their properties depend on magnetospheric conditions, their role in energy and mass transport, how they expand and spread as a function of time, and comparisons with observational data from the THEMIS/ARTEMIS mission.
# How are energetic particles produced during reconnection? This includes mechanisms based on reconnection electric fields and secondary islands. Deliverables include the relative importance of various particle acceleration mechanisms and the observational signatures that result, and observations of these events from THEMIS/ARTEMIS and MMS.

====Term of Focus Group====

Five years (2013-2017)

====Expected Activities, Session Topics, and Challenges====

The following are a possible set of activities and session topics for the duration of the
proposed Focus Group. This list is not intended to be binding, nor is it intended to be noninclusive
to research in areas planned for other years, but is offered as a guide to the direction
of the Focus Group.
Year 1, Signatures of Kinetic Scale Reconnection Physics (2013) - This is important in the runup
to the launch of the MMS mission. The state-of-the-art in kinetic simulations will be gathered
and discussed in relation to existing observational data to make predictions for MMS.
Year 2, Dayside Reconnection and Solar Wind-Magnetospheric Coupling (2014) - This activity
will collect progress in determining how reconnection occurs at the magnetopause and how it
impacts solar wind-magnetospheric coupling. Cross-disciplinary activities with the
Magnetosheath group are possible.
Year 3, Kinetic Physics of Reconnection and Particle Acceleration (2015) - With early results
from MMS expected, this session will focus on analyzing this data and comparing it to numerical
simulations. It is expected that particle acceleration will be a strong component of the
observations. Cross-disciplinary activities with the Metrics and Validation group are possible.
Year 4, Reconnection Onset and Transients (2016) - This session will address the role of
transients and reconnection onset. Cross-disciplinary activities with the Tail-Inner
Magnetosphere Interactions group are possible.
Year 5, Understanding Three-dimensional Reconnection (2017) - Efforts on the challenging and
largely unknown physics of three-dimensional reconnection will be gathered and discussed.

===2015 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting. We also welcome Yi-Hsin Liu and Brian Walsh to our team of co-chairs, and offer thanks to Homa Karimabadi for his years of service.

Last year, we employed two "scene setting" talks per session to frame relevant questions and generate discussion for the remainder of the session. We intend to use a similar strategy this year. We are in the process of lining up speakers, but if you would like to nominate someone (including a self-nomination) for any of the sessions listed below, please email Paul.Cassak at mail.wvu.edu with the name(s) and a brief justification.

Others are encouraged to enhance the discussion by showing a slide or two as appropriate, and we expect some time for open discussion. As in the past, we are asking participants to not do AGU-style presentations, opting for discussion and real-time progress instead. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

The (currently scheduled) dates, times, and summaries for each session are:

====Tuesday 6/16, 1:30pm-3:00pm (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)====

This session will focus on reconnection in the magnetotail and its effects on the inner magnetosphere. In particular, a topic that has generated a lot of interest of late are the kinetic processes associated with energy conversion and the formation and consequences of dipolarization fronts. We also encourage discussion on reconnection onset in the magnetotail - tearing vs. ballooning/interchange. Other relevant topics are welcome.

====Wednesday 6/17, 3:30pm-5:00pm (Joint with "Metrics and Validation" Focus Group)====

The Magnetospheric Multiscale (MMS) satellites were recently launched to measure the electron dissipation region during magnetic reconnection. NASA's Community Coordinated Modeling Center (CCMC), a repository of codes and models with runs-on-request, is pursuing support of MMS science, including the implementation of particle-in-cell simulations to their portfolio. This session will include a discussion of what capabilities members of the community (modelers and observers alike) would like from CCMC for MMS science.

====Thursday 6/18, 1:30pm-3:00pm (Joint with "Geospace System Science"Focus Group)====

This session will encourage cross-focus group interaction and open ended discussion on the topic of "What is the interplay between local and global processes in regulating reconnection?" This can include local-scale (Alfven speeds, microphysics, plasma state and composition, magnetic field geometry), meso-scale (geometry of the magnetic configuration, impediment of outflows), and global-scale (magnetospheric geometry and inflation, current closure through the magnetosheath, ionospheric conductivity, ionospheric outflows). We expect observers, theorists, and modelers interested in the magnetosphere as a system will find this session interesting.

====Thursday 6/18, 3:30pm-5:00pm (Individual session)====

This session will be an open forum for discussion of topics about reconnection in the magnetosphere. We expect dayside reconnection to be a main topic of this session. We encourage discussion on topics of local vs. global control of dayside reconnection and the role of diamagnetic effects and flow shear on dayside reconnection. We encourage people interested in opening a discussion on a topic (the ones listed or otherwise) to attend. Please email Paul.Cassak at mail.wvu.edu by June 9 if you would like to propose a discussion topic.

We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions, and see you in Snowmass.

===2014 GEM Workshop Plans===

We are announcing plans for the "Magnetic Reconnection in the
Magnetosphere" Focus Group sessions at the upcoming GEM Meeting.

The format for each is to have two speakers set the scene on a
particular topic. Others are encouraged to contribute to the
discussion and put up a slide or two as relevant. Half of one session
will be for general contributions consisting of no more than 4 slides
- 1 for intro to acclimate graduate students, and no more than 3 on
your topic. If you would like to be considered for one of the general
contributions, please email Paul.Cassak at mail.wvu.edu with your
topic. We will try to accommodate as many of the requests for talks
as possible. We strongly encourage everyone wishing to present to
sign up to give a poster to ensure you are able to present more than a
few slides. Please let one of the focus group chairs know if you have
any comments or questions.

The dates, times, locations, and summaries for each session are
described here:

====Monday 6/16, 10:30am-12:15pm, Ports Ballroom I-III====
First half - "What controls the rate of dayside reconnection?"
Scene-setters - Joe Borovsky and Ramon Lopez
Science - It has long been thought that the reconnection rate at the
dayside is controlled by the electric field in the solar wind. Recent
observations that geomagnetic indices are affected by plasmaspheric
drainage plumes called this into question, suggesting local control of
the reconnection rate. This session will tackle this fundamental
question of importance to solar wind-magnetospheric coupling. We will
hear from proponents on each side and discuss how future progress will
be made on these questions.

Second half - "General Contributions"
Scene-setters - None
Science - Please consider contributing a few slides on any topic on
reconnection (provided it is GEM relevant). Observations, modeling,
and theory presentations are encouraged. Again, since we are only
leaving 45 minutes for this session, all potential contributors are
encouraged to also sign up to give a poster.

====Monday 6/16, 1:30pm-3:00pm, Ports Ballroom I-III====
First half - "What determines the cross-tail scale of reconnection
jets?"
Scene-setters - Phil Pritchett and Jiang Liu
Science - Multi-satellite missions have made it accessible to study
the three-dimensional structure of reconnection in the
magnetotail. Observationally, what is the characteristic length in
the out-of-plane direction of the reconnection events? Theoretically,
what physically sets this length? These topics will be discussed in
this session.

Second half - "How is magnetotail reconnection modulated by dayside
reconnection? What is the nature of magnetotail reconnection onset
and transients?"
Scene-setters - Toshi Nishimura and Joachim Birn
Science - Reconnection in the magnetotail onsets abruptly, and is
often bursty. It can further be modulated due to time-dependent
phenomena on the dayside. This session will discuss how reconnection
in the magnetotail responds to modulation from the dayside and what
causes reconnection onset and transients in the
magnetotail. Observational and theoretical/modeling considerations
will be discussed.

====Monday 6/16, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)=====
Scene-setters - Misha Sitnov and Andrei Runov
Science - This joint session will focus on the relationship between
bursty bulk flows/dipolarization fronts and reconnection, both from
the observational and theoretical/modeling perspective. In many ways,
this is a continuation of the1:30-3:00 session, but additional
attention will be paid to
the ramifications on the inner magnetosphere.
Please let Paul.Cassak at mail.wvu.edu or toffo atrice.edu know if you
are interested in contributing.

====Thursday 6/19, 3:30pm-5:00pm, Ports Ballroom I-III====
=====(Joint with "The Magnetosheath" Focus Group)=====
Scene-setters - TBD
Science - We seek observational and theory/simulation speakers who
study
1. the consequences of foreshock and magnetosheath turbulence on
dayside reconnection,
2. the effects of velocity shear and plasma beta on dayside
reconnection,
3. plasma heating in magnetosheath reconnection.
Please send your contribution ideas to session organizers by the 6th
of June(any of the above organizers or petrinec at lmsal.com or
nykyrik at erau.edu)

We look forward to seeing you at the sessions! Please let the
organizers (Paul.Cassak at mail.wvu.edu) know about contributions
by Friday, June 6.

====Abstract====
Magnetic reconnection underlies the dynamics in many aspects of magnetospheric
physics and is critical to the development of a predictive understanding of space weather
phenomena. It importance spans from the dayside where solar wind-magnetospheric coupling
occurs to the nightside where storm and substorm phenomena occur. Many existing Focus
Groups treat reconnection in the context of a particular application, but a Focus Group
specifically on reconnection is being proposed to develop an understanding that could not be
attained from studies on particular applications. Broadly, the proposed Focus Group will
address kinetic physics of reconnection and how it couples to macroscales, reconnection at the
dayside and its relation to solar wind-magnetospheric coupling, three-dimensional reconnection,
reconnection onset and transient behavior and implications for transport, and particle
acceleration in reconnection. The proposed Focus Group is timely as simulations have matured
to the point where they can offer realistic comparisons to observations, and the existing
THEMIS/ARTEMIS and upcoming MMS missions include reconnection physics as a key feature
of their goals. Reconnection is by nature cross-disciplinary and offers many opportunities for
interaction with existing Focus Groups. The proposed reconnection Focus Group is for five
years, and will produce deliverables of import for many aspects of GEM goals.

==== Topic Description ====

During magnetic reconnection, a change in magnetic topology facilitates the conversion
of magnetic energy to kinetic and thermal energy and allows mixing of plasmas on either side of
current sheets. It is the driver of many dynamical behaviors in the magnetosphere that are of
crucial importance to space weather. At the dayside magnetopause, reconnection plays a
critical role in solar wind-magnetospheric coupling and recent evidence suggests it may even
control the coupling efficiency. This process is the driver of magnetospheric convection,
evolution of the radiation belts, and loading of energy in the magnetotail. The release of this
energy in geomagnetic storms and substorms is a result of reconnection in the magnetotail.
Reconnection also produces energetic particles that can damage satellites. At present,
magnetic reconnection is studied separately under the auspices of particular applications within
separate GEM Focus Groups. The proposed Focus Group will address the physics of
reconnection as a distinct physical process which is important for magnetospheric applications
in ways that cannot be addressed in applied settings. There is a long history of success in GEM
on reconnection (including the highly-cited GEM Reconnection Challenge). The proposed
Focus Group will foster interaction between observations, simulations, and models. The broad
goals of the Reconnection Focus Group are to contribute to the understanding of (1) the kinetic
microphysics of reconnection and how it couples to the magnetosphere at macroscales, (2) how
and where dayside reconnection occurs and how it contributes to solar wind-magnetospheric
coupling including the role of flux transfer events, (3) how three-dimensional reconnection
proceeds, especially at the dayside, (4) the onset of reconnection and the physics of transient
reconnection events and their relation to bursty bulk flows, dipolarization fronts, and entropy
bubbles, and (5) how reconnection produces energetic particles. Recent advances in fluid and
kinetic simulations both locally at reconnection sites and globally containing the whole
magnetosphere have led to a point where realistic numerical models can be compared directly
with satellite observations. The Focus Group will benefit from a wealth of observational data
from existing satellites, as well as new highly resolved multi-point observational data from the
THEMIS/ARTEMIS mission and the upcoming Magnetospheric MultiScale (MMS) mission.
Strong ties with existing Focus Groups studying applications of reconnection will be made.

==== Timeliness of the Focus Group ====

A GEM Focus Group on magnetic reconnection is particularly timely. NASAs
Magnetospheric MultiScale (MMS) Mission, with a planned launch date of October of 2014,
"will use Earth's magnetosphere as a laboratory to study magnetic reconnection" (http://
mms.gsfc.nasa.gov/about_mms.html), focussing on the kinetic-scale microphysics. This
requires spacecraft to be closer together than previous missions and will provide unprecedented
observational resolution. The three-probe THEMIS constellation will also be reconfigured to
form a larger scale tetrahedron with MMS at one node to provide the macroscopic context for
the microscopic measurements by MMS. In addition, the ARTEMIS satellites repurposed from
the THEMIS mission have recently moved into a lunar orbit and will provide information on the
mid-tail region where reconnection is expected to occur and serve as a solar wind monitor on
the dayside. Therefore, near-future in-situ observations will provide measurements at a wide
scale range from the electron kinetic scale to the global scale. In the run-up to launch of MMS,
a GEM Focus Group on reconnection emphasizing numerical and observational studies will play
a central role in preparing for the mission by investigating what signals should be expected and
in what locations of the magnetosphere. After the launch of MMS, the GEM Focus Group will be
an avenue for analyzing and interpreting the data with comparisons to simulations and for
putting the newly obtained knowledge in context of larger-scale magnetospheric behavior.

==== Relation to Existing GEM Focus Groups ====

As magnetic reconnection underlies dynamics in every GEM Research Area, this Focus
Group has enormous potential for interaction with existing Focus Groups. It is the goal of this Focus Group to both support existing efforts in other Focus Groups and to drive new avenues of research through discovery achieved in this Focus Group. A non-exhaustive discussion follows for ways in which a reconnection Focus Group is synergistic with existing Focus Groups. For each example listed, the Co-Chairs of the existing Focus Group have been contacted and agree that interdisciplinary activities with a reconnection Focus Group would be desirable.

# Plasmasphere-Magnetosphere Interactions (2008-13) - The PMI Focus Group is an example where previous incarnations of reconnection studies at GEM have successfully had interdisciplinary activities. The previous reconnection focus group produced studies on asymmetric reconnection and how it may occur at the dayside magnetosphere. Recent studies showed that solar wind-magnetospheric coupling is less efficient when high density plasmaspheric drainage plumes reach the dayside reconnection site. This is consistent with reconnection becoming less efficient when asymmetric reconnection occurs with high density plasma. A presentation on this was given in a PMI session. Though the PMI Focus Group will end soon, it is expected that the previous interdisciplinary activities will continue.
# Substorm Expansion Onset: The First 10 Minutes (2008-13) - This is another example where there has been cross-participation in the past. The physics of dipolarization fronts and how they can be used to understand reconnection onset in substorms is common to both groups, as it was recently determined that they occur at the onset of reconnection. Kinetic simulations have been very useful to understand their properties.
# Magnetosheath (2010-14) - The magnetosheath is strongly linked to dayside reconnection physics. Many issues of the structure of the magnetosheath are related to how reconnection proceeds, such as the appearance or lack of flux pile-up at the magnetopause and the propensity for flux transfer events. Understanding how kinetic effects impact dayside reconnection and the march to global kinetic modeling, and where reconnection at the dayside occurs as a function of solar wind conditions, are both synergistic topics.
# Metrics and Validation (2011-15) - This group addresses challenges of model-data comparisons and how to assess them. In the past, a barrier to performing careful metrics and validation studies of magnetic reconnection has been a lack of sufficient observations, but the MMS mission is expected to change this. Therefore, a potential avenue for collaboration with the Metrics and Validation Focus Group is comparisons of kinetic modeling and observational data from MMS.
# Tail-Inner Magnetosphere Interactions (2012-16) - This Focus Group addresses modes of transport that cause heating in the magnetotail and inner magnetosphere. It is thought that transient events such as bursty bulk flows, entropy bubbles, and dipolarization fronts play a potentially important role. As these events are associated with magnetotail reconnection, there is strong potential for cross-disciplinary interactions with this Focus Group.

====Goals and Deliverables====

The goals of the Reconnection Focus Group are to understand aspects of
magnetospheric reconnection with an eye to applications in other Focus Groups. This list is not
exhaustive, but it has been compiled using input from the GEM community.

# What is the physics of reconnection at the kinetic scale and how does it couple to the magnetosphere at macro-scales? Particular topics include the role of the extended electron diffusion region, pressure anisotropies, normal magnetic fields for magnetotail applications, asymmetries in density and magnetic field, and whether or how the microphysics of reconnection can be incorporated into fluid models in geospace general circulation models (GGCMs). Examples of deliverables for simulation and modeling work include answers to the following questions - What sets the scale of the extended electron diffusion region and what is its effect on reconnection? (This will be important both before and after the launch of MMS for locating and analyzing reconnection events.) How do asymmetries effect the kinetic signatures of reconnection? Under what conditions do pressure anisotropies arise? Observational deliverables include THEMIS/ARTEMIS and MMS results, which will be compared to numerical simulations.
# How does reconnection proceed at the dayside and how does it contribute to solar wind-magnetospheric coupling? Topics include the role of asymmetries and shear flow in setting the efficiency of reconnection and the role of flux transfer events. Deliverables include quantitative predictions of dayside reconnection efficiency as a function of solar wind conditions that can be fed into solar wind-magnetospheric coupling functions as in the Borovsky coupling function and expected properties of flux transfer events in kinetic simulations and observations.
# How does three-dimensional reconnection proceed, especially at the dayside? Numerical deliverables include answering these questions - What is the location of reconnection on the dayside and its efficiency as a function of solar wind conditions? What differences are there between in 2D and fully 3D reconnection? Observational deliverables include signatures of the dissipation region in fully 3D settings and their meso- and macro-scale ramifications.
# How does reconnection onset and what is the physics of transient reconnection events such as bursty bulk flows, dipolarization fronts, entropy bubbles, and flux transfer events? Deliverables include how their properties depend on magnetospheric conditions, their role in energy and mass transport, how they expand and spread as a function of time, and comparisons with observational data from the THEMIS/ARTEMIS mission.
# How are energetic particles produced during reconnection? This includes mechanisms based on reconnection electric fields and secondary islands. Deliverables include the relative importance of various particle acceleration mechanisms and the observational signatures that result, and observations of these events from THEMIS/ARTEMIS and MMS.

====Expected Activities, Session Topics, and Challenges====

The following are a possible set of activities and session topics for the duration of the
proposed Focus Group. This list is not intended to be binding, nor is it intended to be noninclusive
to research in areas planned for other years, but is offered as a guide to the direction
of the Focus Group.
Year 1, Signatures of Kinetic Scale Reconnection Physics (2013) - This is important in the runup
to the launch of the MMS mission. The state-of-the-art in kinetic simulations will be gathered
and discussed in relation to existing observational data to make predictions for MMS.
Year 2, Dayside Reconnection and Solar Wind-Magnetospheric Coupling (2014) - This activity
will collect progress in determining how reconnection occurs at the magnetopause and how it
impacts solar wind-magnetospheric coupling. Cross-disciplinary activities with the
Magnetosheath group are possible.
Year 3, Kinetic Physics of Reconnection and Particle Acceleration (2015) - With early results
from MMS expected, this session will focus on analyzing this data and comparing it to numerical
simulations. It is expected that particle acceleration will be a strong component of the
observations. Cross-disciplinary activities with the Metrics and Validation group are possible.
Year 4, Reconnection Onset and Transients (2016) - This session will address the role of
transients and reconnection onset. Cross-disciplinary activities with the Tail-Inner
Magnetosphere Interactions group are possible.
Year 5, Understanding Three-dimensional Reconnection (2017) - Efforts on the challenging and
largely unknown physics of three-dimensional reconnection will be gathered and discussed.
