= Conductance Challenge =

Hi everyone,

As we prepare for the upcoming GEM Workshop, I wanted to send out a reminder to everyone about our conductance challenge!

At Mini-GEM, we had talks by Steve Kaeppler, Tomoko Matsuo, Margaret Chen, and Bill Lotko.

'''Kaeppler - What does Incoherent Scatter Radar bring to Conductance Specification?'''

https://drive.google.com/open?id=0B7EPr-LPOL6FQVZiekdsSkMtUEE

'''Matsuo - Role of the Conductance in Making Sense of High-latitude Geospace Observations'''

https://drive.google.com/open?id=0B7EPr-LPOL6FU2dKRWdqbnZCT00

'''Chen - Efforts to Improve Modeling of Ionospheric Conductance and Inner Magnetospheric Electric'''

'''Lotko - M-I Coupling in Global MHD Simulations'''

https://drive.google.com/open?id=0B7EPr-LPOL6FcjBTMjdGZkRWdVE

We’re also preparing for the GEM Conductance Challege. We’ve selected for the first challenge 2016 Oct 13-15 ICME (Dst=-104, F10.7=95)
This event is the same as the Outflow Challenge event #2, so we can expect some great overlap and collaboration there. If you have any conductance-related data or simulations, please bring them in June, and we’ll start crafting the mechanics of the challenge.

The following storms have also been suggested: 
2010/04/05 
2011/04/30 
2011/08/06 
2012/05/07 
2013/03/17 
2014/01/07 
2015/03/17 
2015/06/22 
2015/12/20 
2016/01/20 
2016/03/07 
3016/05/07 

We’ll vote on the second challenge storm at our upcoming workshop, so come ready to discuss your favorite storm. If you have any to add to the list of potential storms, then let us know!

In addition to a session on our conductance challenge, we’ll also have a general validation session: Validation: Successes and Pitfalls, where we welcome new validation results that don’t fit into the other GEM sessions, as well as having a general discussion of best practices in model/data comparison and model validation.

We’re looking forward to seeing you in June!

Best,
Katie, Rob, Lutz, and Mike

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!

Location: Holley Ballroom

'''Dayside Kinetics Challenge Session'''

The southward IMF event on 2015-11-18 01:50-03:00 UT, featuring an MMS-Geotail magnetopause conjunction with SuperDARN radar observations has been set as the challenge event. During this challenge we analyze the various dayside phenomena (magnetic reconnection, FTEs, magnetosheath waves, etc). We aim to conduct comparisons between (i) observations and models with different levels of kinetic physics; (ii) different models; (iii) in situ and remote observations. You can find more information at: https://ccmc.gsfc.nasa.gov/support/GEM/Dayside_Kinetic_Processes/Dayside_Kinetic_Challenge/Introduction.php

In this session, we will have several presentations of the observations made throughout the magnetosphere during this event, as well as on the preliminary simulations. We encourage both modelers and data analysts to attend and participate in the discussions and decisions on the next steps of the challenge.

==== [FG] Magnetic Reconnection in the Magnetosphere + Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction ====

Location: Amphitheater

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.

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!

Location: Holley Ballroom

'''Dayside Kinetics Challenge Session'''

The southward IMF event on 2015-11-18 01:50-03:00 UT, featuring an MMS-Geotail magnetopause conjunction with SuperDARN radar observations has been set as the challenge event. During this challenge we analyze the various dayside phenomena (magnetic reconnection, FTEs, magnetosheath waves, etc). We aim to conduct comparisons between (i) observations and models with different levels of kinetic physics; (ii) different models; (iii) in situ and remote observations. You can find more information at: https://ccmc.gsfc.nasa.gov/support/GEM/Dayside_Kinetic_Processes/Dayside_Kinetic_Challenge/Introduction.php

In this session, we will have several presentations of the observations made throughout the magnetosphere during this event, as well as on the preliminary simulations. We encourage both modelers and data analysts to attend and participate in the discussions and decisions on the next steps of the challenge.

==== [FG] Magnetic Reconnection in the Magnetosphere + Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction ====

Location: Amphitheater

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.

==== [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.

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.

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.

==== [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!

Different global MHD models (LFM, OpenGGCM, BATS-R-US, and GUMICS) will be presented.

The models will be compared with ARTEMIS observations in mid-tail and with ionosphere observations from SuperDARN, DMSP, SWARM, AMPERE, and ground magnetometers.

We will address three science questions: (1) What processes cause the 10 to 30 min perturbations in the mid-tail plasma sheet? (2) How does the mid-tail configuration response to changes in IMF By? (3) How is the coupling between the ionosphere and mid-tail?

==== [FG] Magnetic Reconnection in the Magnetosphere + Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction ====

Location: Amphitheater

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.

''Planning session for the Ionospheric Conductance Challenge''

First event: 2016 Oct 13-15 ICME event. The concept for the challenge is that modelers would run at least two versions of their code, one with an "old" conductance specification and another with a "new" specification. At this session, we will decide on common settings between model runs and specific data-model comparisons that all teams should conduct.

We're currently working with other focus groups on science-focused challenges: 
ULF Waves 
Mid-Tail Modeling 
Dayside Kinetics 
Ionospheric Outflow 

Contact: Katherine Garcia-Sage, Lutz Rastaetter, Rob Redmon, and/or Mike Liemohn

We'll also have a general validation session at the upcoming GEM 2017 workshop, so stay tuned for details, and contact us if you'd like to be involved in any way.

= Conductance Challenge =

Hi everyone,

As we prepare for the upcoming GEM Workshop, I wanted to send out a reminder to everyone about our conductance challenge!

At Mini-GEM, we had talks by Steve Kaeppler, Tomoko Matsuo, Margaret Chen, and Bill Lotko.

'''Kaeppler - What does Incoherent Scatter Radar bring to Conductance Specification?'''

https://drive.google.com/open?id=0B7EPr-LPOL6FQVZiekdsSkMtUEE

'''Matsuo - Role of the Conductance in Making Sense of High-latitude Geospace Observations'''

'''Chen - Efforts to Improve Modeling of Ionospheric Conductance and Inner Magnetospheric Electric'''

'''Lotko - M-I Coupling in Global MHD Simulations'''

https://drive.google.com/open?id=0B7EPr-LPOL6FcjBTMjdGZkRWdVE

We’re also preparing for the GEM Conductance Challege. We’ve selected for the first challenge 2016 Oct 13-15 ICME (Dst=-104, F10.7=95)
This event is the same as the Outflow Challenge event #2, so we can expect some great overlap and collaboration there. If you have any conductance-related data or simulations, please bring them in June, and we’ll start crafting the mechanics of the challenge.

The following storms have also been suggested: 
2010/04/05 
2011/04/30 
2011/08/06 
2012/05/07

We’ll vote on the second challenge storm at our upcoming workshop, so come ready to discuss your favorite storm. If you have any to add to the list of potential storms, then let us know!

In addition to a session on our conductance challenge, we’ll also have a general validation session: Validation: Successes and Pitfalls, where we welcome new validation results that don’t fit into the other GEM sessions, as well as having a general discussion of best practices in model/data comparison and model validation.

We’re looking forward to seeing you in June!
