== 2017 Workshop Tentative Agenda ==

http://gem.epss.ucla.edu/mediawikiwiki/index.php/2017_GEM_Workshop

== Focus Group Leaders ==

* '''Kyle Murphy''' (NASA GSFC)
* '''Toshi Nishimura''' (UCLA)
* '''Emma Spanswick''' (University of Calgary)
* '''Jian Yang''' (Rice University)

== Term ==
* 2015-2019 (5 years)

== Research Area ==
* Magnetotail and Plasma Sheet (MPS)

== Abstract ==

For decades the debate on substorms had centered on the ‘outside-in’ (reconnection) and ‘inside-out’ (current disruption) scenarios. However, recent ground-based observations have suggested a hybrid model, wherein the substorm is initiated by flows that may originate from the dayside, cross the polar cap, move through the open/closed boundary where they trigger localized reconnection, and then trigger substorm expansion after reaching the near-Earth transition region. This is radically different from the previous and intensely debated proposals. However, there are important disagreements in the community regarding both the interpretation of the ground-based (ASI, redline, and radar) observations and the proposed picture. Furthermore, the complete idea now includes the new proposal that flow structures from within the polar cap trigger localized tail reconnection, an idea which is of major importance for full understanding of tail reconnection, but which has not received much attention in the past. It is the purpose of this proposed focus group to bring together key players in this area to work together on the new questions of the auroral and magnetotail sequence leading to substorm onset, in a CDAW/GEM style format. Though our central focus is on substorms, we will also compare to non-substorm time phenomena because some key features are common in different levels of magnetic activity. Due to the structure of GEM as a working group style meeting, and the potential impact of this new paradigm on understanding the Geospace environment, GEM is the ideal venue through which to rigorously evaluate the newly proposed paradigms. Due to the importance of ground-based observations for the proposed topics, this focus group will encourage collaboration between GEM and CEDAR.

== Topics ==

* ''' Can we rigorously evaluate substorm precursor occurrence and association? '''
* ''' What are similarities and differences of PBIs/streamers/plasma sheet flows during isolated substorms, active‐time substorms and non‐substorm times? '''
* ''' What can auroral observation tell us about the sources, timing and properties of magnetospheric flows? '''
* ''' How does the asymmetric and bursty nature of plasma sheet transport and plasma sheet wave instability influence substorm onset and other types of auroral brightening? '''
* ''' How do plasma sheet fast flows/streamers couple to lobe/polar cap phenomena? '''

== Timeliness ==

It has now been five years since the initial work of Nishimura et al. [2010] and Lyons et al. [2010], and the group has now expanded their work with numerous follow-on studies. There is therefore sufficient evidence that something of interest is occurring; yet a significant number of studies that questions their finding exist, and there is yet to be a consensus on interpretation of the data. There is intense scientific interest in the community on this topic, and the discussions have reached a critical stage. In addition to a large amount of existing satellite and ground-based data, this focus group will provide a stage to discuss initial results from new data, including those from a new campaign of THEMIS-MMS-ground coordination in year 2015-2017, and new redline (6300 Å) data from highly sensitive cameras. A focus group on this topic couldn't be more timely or appropriate for GEM.

== Relation to existing focus groups ==
Currently there exists no FG where the type of activity described here could occur. This FG will work with the “Scientific Magnetic Mapping & Techniques” FG, as well as the “Tail-inner magnetosphere interactions” FG, from the standpoint of ‘bubbles’, and "Magnetic Reconnection in the Magnetosphere" FG. Additionally, once the observable features are better quantified, the results could be fed into the “Geospace Systems Science" FG for better integration with the global models and systems-science methodologies that are the focus of that group.

== Goals and deliverables ==
The primary goal of the focus group is to determine if, when, and under what conditions, localized flux tubes convecting across the polar cap lead to depleted entropy flow bursts within the plasmasheet that can trigger the reconfiguration of the nightside magnetosphere that is known as a substorm. The result of the FG will be a rigorous community assessment of the role of pre-onset polar cap flows and auroral zone streamers (as proxies for magnetospheric flows) on magnetospheric reconfiguration, as well as on localized tail reconnection. In addition to a series of published research papers, the results will be communicated directly to the GGCM modelers, as these new observations provide new constraints and metrics that the models will have to match.

* Community-wide consensus of substorm precursors
* Consensus on connection between the lobe (polar cap) and plasma sheet (oval) and its influence on reconnection and substorm
* Developing tools to quantify key auroral features (such as streamers)
* Model validations by characterizing location, size, motion and timing of precursors
* A series of publications on these outcomes

== Expected Activities ==
This will primarily be an intensive data analysis focus group, with immersive discussions and very few presentations. We will invite a small number of speakers (both from GEM and CEDAR) to present their results on selected events, and ask several experienced community members to join as panelists for facilitating discussions with audience. We will also encourage modelers to present simulation results for assisting interpretation of observations and for obtaining physical pictures. One goal is to return to the original GEM model of active data analysis, and we may try a ‘two-screen’ approach to improve interactions and discussions.

A primary objective of the proposed focus group is to reach consensus on the significance of and how to interpret auroral streamers and polar patches, and their associated flow structures, in the context of substorm development. For the first two years we anticipate a few short presentations to provide the framework, then the team will work on identifying a subset of events to analyze in detail (this will also occur well before each summer workshop) – starting first with isolated substorms, then moving onto intensifications embedded in strong activity. In later years, similarities and differences of substorm-time and nonsubstorm-time sequences will be discussed.

== Timeliness ==

It has now been five years since the initial work of Nishimura et al. [2010] and Lyons et al. [2010], and the group has now expanded their work with numerous follow-on studies. There is therefore sufficient evidence that something of interest is occurring; yet a significant number of studies that questions their finding exist, and there is yet to be a consensus on interpretation of the data. There is intense scientific interest in the community on this topic, and the discussions have reached a critical stage. In addition to a large amount of existing satellite and ground-based data, this focus group will provide a stage to discuss initial results from new data, including those from a new campaign of THEMIS-MMS-ground coordination in year 2015-2017, and new redline (6300 Å) data from highly sensitive cameras. A focus group on this topic couldn't be more timely or appropriate for GEM.

== Relation to existing focus groups ==
Currently there exists no FG where the type of activity described here could occur. This FG will work with the “Scientific Magnetic Mapping & Techniques” FG, as well as the “Tail-inner magnetosphere interactions” FG, from the standpoint of ‘bubbles’, and "Magnetic Reconnection in the Magnetosphere" FG. Additionally, once the observable features are better quantified, the results could be fed into the “Geospace Systems Science" FG for better integration with the global models and systems-science methodologies that are the focus of that group.

== Goals and deliverables ==
The primary goal of the focus group is to determine if, when, and under what conditions, localized flux tubes convecting across the polar cap lead to depleted entropy flow bursts within the plasmasheet that can trigger the reconfiguration of the nightside magnetosphere that is known as a substorm. The result of the FG will be a rigorous community assessment of the role of pre-onset polar cap flows and auroral zone streamers (as proxies for magnetospheric flows) on magnetospheric reconfiguration, as well as on localized tail reconnection. In addition to a series of published research papers, the results will be communicated directly to the GGCM modelers, as these new observations provide new constraints and metrics that the models will have to match.

* Community-wide consensus of substorm precursors
* Consensus on connection between the lobe (polar cap) and plasma sheet (oval) and its influence on reconnection and substorm
* Developing tools to quantify key auroral features (such as streamers)
* Model validations by characterizing location, size, motion and timing of precursors
* A series of publications on these outcomes

== Expected Activities ==
This will primarily be an intensive data analysis focus group, with immersive discussions and very few presentations. We will invite a small number of speakers (both from GEM and CEDAR) to present their results on selected events, and ask several experienced community members to join as panelists for facilitating discussions with audience. We will also encourage modelers to present simulation results for assisting interpretation of observations and for obtaining physical pictures. One goal is to return to the original GEM model of active data analysis, and we may try a ‘two-screen’ approach to improve interactions and discussions.

A primary objective of the proposed focus group is to reach consensus on the significance of and how to interpret auroral streamers and polar patches, and their associated flow structures, in the context of substorm development. For the first two years we anticipate a few short presentations to provide the framework, then the team will work on identifying a subset of events to analyze in detail (this will also occur well before each summer workshop) – starting first with isolated substorms, then moving onto intensifications embedded in strong activity. In later years, similarities and differences of substorm-time and nonsubstorm-time sequences will be discussed.

== Term ==
* 2015-2019 (5 years)

== Research Area ==
* Magnetotail and Plasma Sheet (MPS)

== Abstract ==

For decades the debate on substorms had centered on the ‘outside-in’ (reconnection) and ‘inside-out’ (current disruption) scenarios. However, recent ground-based observations have suggested a hybrid model, wherein the substorm is initiated by flows that may originate from the dayside, cross the polar cap, move through the open/closed boundary where they trigger localized reconnection, and then trigger substorm expansion after reaching the near-Earth transition region. This is radically different from the previous and intensely debated proposals. However, there are important disagreements in the community regarding both the interpretation of the ground-based (ASI, redline, and radar) observations and the proposed picture. Furthermore, the complete idea now includes the new proposal that flow structures from within the polar cap trigger localized tail reconnection, an idea which is of major importance for full understanding of tail reconnection, but which has not received much attention in the past. It is the purpose of this proposed focus group to bring together key players in this area to work together on the new questions of the auroral and magnetotail sequence leading to substorm onset, in a CDAW/GEM style format. Though our central focus is on substorms, we will also compare to non-substorm time phenomena because some key features are common in different levels of magnetic activity. Due to the structure of GEM as a working group style meeting, and the potential impact of this new paradigm on understanding the Geospace environment, GEM is the ideal venue through which to rigorously evaluate the newly proposed paradigms. Due to the importance of ground-based observations for the proposed topics, this focus group will encourage collaboration between GEM and CEDAR.

==== [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.

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.

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!

==== [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. 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!

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] (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!

== Abstract ==

For decades the debate on substorms had centered on the ‘outside-in’ (reconnection) and ‘inside-out’ (current disruption) scenarios. However, recent ground-based observations have suggested a hybrid model, wherein the substorm is initiated by flows that may originate from the dayside, cross the polar cap, move through the open/closed boundary where they trigger localized reconnection, and then trigger substorm expansion after reaching the near-Earth transition region. This is radically different from the previous and intensely debated proposals. However, there are important disagreements in the community regarding both the interpretation of the ground-based (ASI, redline, and radar) observations and the proposed picture. Furthermore, the complete idea now includes the new proposal that flow structures from within the polar cap trigger localized tail reconnection, an idea which is of major importance for full understanding of tail reconnection, but which has not received much attention in the past. It is the purpose of this proposed focus group to bring together key players in this area to work together on the new questions of the auroral and magnetotail sequence leading to substorm onset, in a CDAW/GEM style format. Though our central focus is on substorms, we will also compare to non-substorm time phenomena because some key features are common in different levels of magnetic activity. Due to the structure of GEM as a working group style meeting, and the potential impact of this new paradigm on understanding the Geospace environment, GEM is the ideal venue through which to rigorously evaluate the newly proposed paradigms. Due to the importance of ground-based observations for the proposed topics, this focus group will encourage collaboration between GEM and CEDAR.

== Timeliness ==

It has now been five years since the initial work of Nishimura et al. [2010] and Lyons et al. [2010], and the group has now expanded their work with numerous follow-on studies. There is therefore sufficient evidence that something of interest is occurring; yet a significant number of studies that questions their finding exist, and there is yet to be a consensus on interpretation of the data. There is intense scientific interest in the community on this topic, and the discussions have reached a critical stage. In addition to a large amount of existing satellite and ground-based data, this focus group will provide a stage to discuss initial results from new data, including those from a new campaign of THEMIS-MMS-ground coordination in year 2015-2017, and new redline (6300 Å) data from highly sensitive cameras. A focus group on this topic couldn't be more timely or appropriate for GEM.

== Relation to existing focus groups ==
Currently there exists no FG where the type of activity described here could occur. This FG will work with the “Scientific Magnetic Mapping & Techniques” FG, as well as the “Tail-inner magnetosphere interactions” FG, from the standpoint of ‘bubbles’, and "Magnetic Reconnection in the Magnetosphere" FG. Additionally, once the observable features are better quantified, the results could be fed into the “Geospace Systems Science" FG for better integration with the global models and systems-science methodologies that are the focus of that group.

== Goals and deliverables ==
The primary goal of the focus group is to determine if, when, and under what conditions, localized flux tubes convecting across the polar cap lead to depleted entropy flow bursts within the plasmasheet that can trigger the reconfiguration of the nightside magnetosphere that is known as a substorm. The result of the FG will be a rigorous community assessment of the role of pre-onset polar cap flows and auroral zone streamers (as proxies for magnetospheric flows) on magnetospheric reconfiguration, as well as on localized tail reconnection. In addition to a series of published research papers, the results will be communicated directly to the GGCM modelers, as these new observations provide new constraints and metrics that the models will have to match.

* Community-wide consensus of substorm precursors
* Consensus on connection between the lobe (polar cap) and plasma sheet (oval) and its influence on reconnection and substorm
* Developing tools to quantify key auroral features (such as streamers)
* Model validations by characterizing location, size, motion and timing of precursors
* A series of publications on these outcomes

== Expected Activities ==
This will primarily be an intensive data analysis focus group, with immersive discussions and very few presentations. We will invite a small number of speakers (both from GEM and CEDAR) to present their results on selected events, and ask several experienced community members to join as panelists for facilitating discussions with audience. We will also encourage modelers to present simulation results for assisting interpretation of observations and for obtaining physical pictures. One goal is to return to the original GEM model of active data analysis, and we may try a ‘two-screen’ approach to improve interactions and discussions.

A primary objective of the proposed focus group is to reach consensus on the significance of and how to interpret auroral streamers and polar patches, and their associated flow structures, in the context of substorm development. For the first two years we anticipate a few short presentations to provide the framework, then the team will work on identifying a subset of events to analyze in detail (this will also occur well before each summer workshop) – starting first with isolated substorms, then moving onto intensifications embedded in strong activity. In later years, similarities and differences of substorm-time and nonsubstorm-time sequences will be discussed.

* Magnetotail and Plasma Sheet (MPS)

== Abstract ==

For decades the debate on substorms had centered on the ‘outside-in’ (reconnection) and ‘inside-out’ (current disruption) scenarios. However, recent ground-based observations have suggested a hybrid model, wherein the substorm is initiated by flows that may originate from the dayside, cross the polar cap, move through the open/closed boundary where they trigger localized reconnection, and then trigger substorm expansion after reaching the near-Earth transition region. This is radically different from the previous and intensely debated proposals. However, there are important disagreements in the community regarding both the interpretation of the ground-based (ASI, redline, and radar) observations and the proposed picture. Furthermore, the complete idea now includes the new proposal that flow structures from within the polar cap trigger localized tail reconnection, an idea which is of major importance for full understanding of tail reconnection, but which has not received much attention in the past. It is the purpose of this proposed focus group to bring together key players in this area to work together on the new questions of the auroral and magnetotail sequence leading to substorm onset, in a CDAW/GEM style format. Though our central focus is on substorms, we will also compare to non-substorm time phenomena because some key features are common in different levels of magnetic activity. Due to the structure of GEM as a working group style meeting, and the potential impact of this new paradigm on understanding the Geospace environment, GEM is the ideal venue through which to rigorously evaluate the newly proposed paradigms. Due to the importance of ground-based observations for the proposed topics, this focus group will encourage collaboration between GEM and CEDAR.

Substorms2015: /* 2015 Workshop Tentative Agenda */

== 2015 Workshop Tentative Agenda ==

http://gem.epss.ucla.edu/mediawikiwiki/index.php/2015_Summer_Workshop

== Focus Group Leaders ==

* '''Kyle Murphy''' (NASA GSFC)
* '''Toshi Nishimura''' (UCLA)
* '''Emma Spanswick''' (University of Calgary)
* '''Jian Yang''' (Rice University)

== Term ==
* 2015-2019 (5 years)

== Research Area ==
* Magnetotail and Plasma Sheet (MPS)

== Abstract ==

For decades the debate on substorms had centered on the ‘outside-in’ (reconnection) and ‘inside-out’ (current disruption) scenarios. However, recent ground-based observations have suggested a hybrid model, wherein the substorm is initiated by flows that may originate from the dayside, cross the polar cap, move through the open/closed boundary where they trigger localized reconnection, and then trigger substorm expansion after reaching the near-Earth transition region. This is radically different from the previous and intensely debated proposals. However, there are important disagreements in the community regarding both the interpretation of the ground-based (ASI, redline, and radar) observations and the proposed picture. Furthermore, the complete idea now includes the new proposal that flow structures from within the polar cap trigger localized tail reconnection, an idea which is of major importance for full understanding of tail reconnection, but which has not received much attention in the past. It is the purpose of this proposed focus group to bring together key players in this area to work together on the new questions of the auroral and magnetotail sequence leading to substorm onset, in a CDAW/GEM style format. Though our central focus is on substorms, we will also compare to non-substorm time phenomena because some key features are common in different levels of magnetic activity. Due to the structure of GEM as a working group style meeting, and the potential impact of this new paradigm on understanding the Geospace environment, GEM is the ideal venue through which to rigorously evaluate the newly proposed paradigms. Due to the importance of ground-based observations for the proposed topics, this focus group will encourage collaboration between GEM and CEDAR.

== Topics ==

* ''' Can we rigorously evaluate substorm precursor occurrence and association? '''
* ''' What are similarities and differences of PBIs/streamers/plasma sheet flows during isolated substorms, active‐time substorms and non‐substorm times? '''
* ''' What can auroral observation tell us about the sources, timing and properties of magnetospheric flows? '''
* ''' How does the asymmetric and bursty nature of plasma sheet transport and plasma sheet wave instability influence substorm onset and other types of auroral brightening? '''
* ''' How do plasma sheet fast flows/streamers couple to lobe/polar cap phenomena? '''

== Timeliness ==

It has now been five years since the initial work of Nishimura et al. [2010] and Lyons et al. [2010], and the group has now expanded their work with numerous follow-on studies. There is therefore sufficient evidence that something of interest is occurring; yet a significant number of studies that questions their finding exist, and there is yet to be a consensus on interpretation of the data. There is intense scientific interest in the community on this topic, and the discussions have reached a critical stage. In addition to a large amount of existing satellite and ground-based data, this focus group will provide a stage to discuss initial results from new data, including those from a new campaign of THEMIS-MMS-ground coordination in year 2015-2017, and new redline (6300 Å) data from highly sensitive cameras. A focus group on this topic couldn't be more timely or appropriate for GEM.

== Relation to existing focus groups ==
Currently there exists no FG where the type of activity described here could occur. This FG will work with the “Scientific Magnetic Mapping & Techniques” FG, as well as the “Tail-inner magnetosphere interactions” FG, from the standpoint of ‘bubbles’, and "Magnetic Reconnection in the Magnetosphere" FG. Additionally, once the observable features are better quantified, the results could be fed into the “Geospace Systems Science" FG for better integration with the global models and systems-science methodologies that are the focus of that group.

== Goals and deliverables ==
The primary goal of the focus group is to determine if, when, and under what conditions, localized flux tubes convecting across the polar cap lead to depleted entropy flow bursts within the plasmasheet that can trigger the reconfiguration of the nightside magnetosphere that is known as a substorm. The result of the FG will be a rigorous community assessment of the role of pre-onset polar cap flows and auroral zone streamers (as proxies for magnetospheric flows) on magnetospheric reconfiguration, as well as on localized tail reconnection. In addition to a series of published research papers, the results will be communicated directly to the GGCM modelers, as these new observations provide new constraints and metrics that the models will have to match.

* Community-wide consensus of substorm precursors
* Consensus on connection between the lobe (polar cap) and plasma sheet (oval) and its influence on reconnection and substorm
* Developing tools to quantify key auroral features (such as streamers)
* Model validations by characterizing location, size, motion and timing of precursors
* A series of publications on these outcomes

== Expected Activities ==
This will primarily be an intensive data analysis focus group, with immersive discussions and very few presentations. We will invite a small number of speakers (both from GEM and CEDAR) to present their results on selected events, and ask several experienced community members to join as panelists for facilitating discussions with audience. We will also encourage modelers to present simulation results for assisting interpretation of observations and for obtaining physical pictures. One goal is to return to the original GEM model of active data analysis, and we may try a ‘two-screen’ approach to improve interactions and discussions.

A primary objective of the proposed focus group is to reach consensus on the significance of and how to interpret auroral streamers and polar patches, and their associated flow structures, in the context of substorm development. For the first two years we anticipate a few short presentations to provide the framework, then the team will work on identifying a subset of events to analyze in detail (this will also occur well before each summer workshop) – starting first with isolated substorms, then moving onto intensifications embedded in strong activity. In later years, similarities and differences of substorm-time and nonsubstorm-time sequences will be discussed.
