Southward IMF Challenge: simulation-observation comparisons
Two participating modeling teams have joined forces with observers to proceed with the analysis of the 2015-11-18 event. We’ll first hear each collaboration present their simulation-observation comparisons on five prescribed topics: magnetic field and plasma signatures, waves, magnetopause location, and X-line dynamics. We’ll then get a chance to make on-the-spot model-model-observation comparisons. Finally, each collaboration gets to present any extra findings they’ve made. When we reconvene refreshed after the coffee break, we’ll discuss the next steps of this Challenge.

• Heli Hietala, Introduction to Southward IMF challenge

• Yuxi Chen & Sarah Vines, Comparison of MHD-EPIC simulation with observations

• Yu Lin & Sun Lee, Comparison of global 3D hybrid simulation with observations

• Joint comparison and discussion

==== [FG] Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere ====
'''Location: Zia Ballroom''' 
'''Chairs:''' Christine Gabrielse, Drew Turner, David Malaspina, Matina Gkioulidou, Slava Merkin

We will have a panel discussion on the questions below with an aim to communicate different types of models' capabilities to answer different science questions, as well as a discussion on how we can move forward towards improved, data-informed models. We invite the audience to participate in the discussion and to provide input as to how we, as a field, can move forward to better understand how dipolarizations affect the inner magnetosphere, and/or how they are affected by the coupled magnetosphere-ionosphere system.

'''Panelists''' 
Misha Sitnov 
San Lu 
Jimmy Raeder 
Yann Kempf 
Colby Lemon 
Katie Garcia-Sage 

'''Panel Questions'''

1) Given our current modeling capabilities, discuss which kinds of models are best at capturing which aspects of dipolarization events and their effects in the magnetosphere.

2) What determines the dipolarization scale size in different models? (e.g., physical description, boundary conditions, model input parameters, ionosphere conditions, etc.?)

3) The transition region is where both inertia and energy dependent drifts are important. No existing models treat that region correctly.

(a) How do we move forward?

(b) Or, more specifically, address the question of dipolarization front deceleration:
(i) How do various models treat dipolarization deceleration as they approach the inner magnetosphere?
(ii) What processes are decelerating the fronts in the models?
(iii) What inner magnetosphere processes are missing (e.g. plasmasphere, complex ionospheric conductivity models) and does excluding these processes lead to different deceleration predictions?

(c) And/or address:
(i) What are the relative roles of ExB, energy-dependent drifts and particle trapping in transport and energization in the transition region?
(ii) To what extent are these processes adiabatic for particles of different energies?
(iii) What is their overall contribution to the ring current build up?

Although the questions are focusing on dipolarization implementation into the current magnetospheric models, participation of data analysts is highly desired and encouraged in order to establish an observational framework for the models.

*Panelist: Mike Liemohn, Vania Jordanova, George Khazanov, Yihua Zheng

==== [Joint] Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction + Modeling Methods and Validation ====

Dayside-Nightside Connections Challenge: a substorm triggered by magnetosheath jets?
This theme echoes the second half of our FG’s name. Last summer Katariina Nykyri presented an event with great potential for community efforts: an MMS-THEMIS conjunction where timing suggests that a substorm was triggered by transient dayside magnetosheath jets. The FG has taken up the challenge and coordinated activities in preparation for the workshop.

First Chih-Ping Wang will provide an introduction to the theme by presenting an event featuring a foreshock transient propagating to the mid-tail. Katariina Nykyri will then present the challenge event. The following presentations will let us see whether DMSP, SuperDARN, and ground magnetometer observations support the hypothesis.

• Next steps of Southward IMF challenge

• Ying Zou, Introduction to Dayside-Nightside Connections Challenge

• Chih-Ping Wang, Propagation of foreshock transients to mid-tail

• Katariina Nykyri, Challenge event observations using THEMIS & MMS and simulations

• Simon Wing, Challenge event observations using DMSP

• Xueling Shi & Mike Ruohoniemi, Challenge event observations using SuperDARN

• Toshi Nishimura, Challenge event observations using ground magnetometers

• Discussion

Southward IMF Challenge: simulation-observation comparisons
Two participating modeling teams have joined forces with observers to proceed with the analysis of the 2015-11-18 event. We’ll first hear each collaboration present their simulation-observation comparisons on five prescribed topics: magnetic field and plasma signatures, waves, magnetopause location, and X-line dynamics. We’ll then get a chance to make on-the-spot model-model-observation comparisons. Finally, each collaboration gets to present any extra findings they’ve made. When we reconvene refreshed after the coffee break, we’ll discuss the next steps of this Challenge.

• Heli Hietala, Introduction to Southward IMF challenge

• Yuxi Chen & Sarah Vines, Comparison of MHD-EPIC simulation with observations

• Yu Lin & Sun Lee, Comparison of global 3D hybrid simulation with observations

• Joint comparison and discussion

==== [FG] Magnetotail Dipolarization and Its Effects on the Inner Magnetosphere ====
'''Location: Zia Ballroom''' 
'''Chairs:''' Christine Gabrielse, Drew Turner, David Malaspina, Matina Gkioulidou, Slava Merkin

We will have a panel discussion on the questions below with an aim to communicate different types of models' capabilities to answer different science questions, as well as a discussion on how we can move forward towards improved, data-informed models. We invite the audience to participate in the discussion and to provide input as to how we, as a field, can move forward to better understand how dipolarizations affect the inner magnetosphere, and/or how they are affected by the coupled magnetosphere-ionosphere system.

'''Panelists''' 
Misha Sitnov 
San Lu 
Jimmy Raeder 
Yann Kempf 
Colby Lemon 
Katie Garcia-Sage 

'''Panel Questions'''

1) Given our current modeling capabilities, discuss which kinds of models are best at capturing which aspects of dipolarization events and their effects in the magnetosphere.

2) What determines the dipolarization scale size in different models? (e.g., physical description, boundary conditions, model input parameters, ionosphere conditions, etc.?)

3) The transition region is where both inertia and energy dependent drifts are important. No existing models treat that region correctly.

(a) How do we move forward?

(b) Or, more specifically, address the question of dipolarization front deceleration:
(i) How do various models treat dipolarization deceleration as they approach the inner magnetosphere?
(ii) What processes are decelerating the fronts in the models?
(iii) What inner magnetosphere processes are missing (e.g. plasmasphere, complex ionospheric conductivity models) and does excluding these processes lead to different deceleration predictions?

(c) And/or address:
(i) What are the relative roles of ExB, energy-dependent drifts and particle trapping in transport and energization in the transition region?
(ii) To what extent are these processes adiabatic for particles of different energies?
(iii) What is their overall contribution to the ring current build up?

Although the questions are focusing on dipolarization implementation into the current magnetospheric models, participation of data analysts is highly desired and encouraged in order to establish an observational framework for the models.

==== [Joint] Dayside Kinetic Processes in Global Solar Wind-Magnetosphere Interaction + Modeling Methods and Validation ====

Dayside-Nightside Connections Challenge: a substorm triggered by magnetosheath jets?
This theme echoes the second half of our FG’s name. Last summer Katariina Nykyri presented an event with great potential for community efforts: an MMS-THEMIS conjunction where timing suggests that a substorm was triggered by transient dayside magnetosheath jets. The FG has taken up the challenge and coordinated activities in preparation for the workshop.

First Chih-Ping Wang will provide an introduction to the theme by presenting an event featuring a foreshock transient propagating to the mid-tail. Katariina Nykyri will then present the challenge event. The following presentations will let us see whether DMSP, SuperDARN, and ground magnetometer observations support the hypothesis.

• Next steps of Southward IMF challenge

• Ying Zou, Introduction to Dayside-Nightside Connections Challenge

• Chih-Ping Wang, Propagation of foreshock transients to mid-tail

• Katariina Nykyri, Challenge event observations using THEMIS & MMS and simulations

• Simon Wing, Challenge event observations using DMSP

• Xueling Shi & Mike Ruohoniemi, Challenge event observations using SuperDARN

• Toshi Nishimura, Challenge event observations using ground magnetometers

• Discussion

*Storm 1: 2016 Mar 4-8 (DOY 64-68)
*Storm 2: 2016 Oct 11-15 (285-289)
*Possibly: 2016 May 6-10 (127-131)
Especially including new and newly-restored data sets
Other specialized events/studies are welcome, especially those speaking to statistical states. It is important to study not only storm times, but also non-storm times in which the ionosphere is feeding the plasma sheet and building it up steadily prior to any reconnection or storm activity.
This will also be the encouraged focus for M3I2 GEM Mini-Workshop at 2018 Fall AGU.

==== [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!

'''Modeling challenge event: 48 hr of prolonged northward IMF interval from 13 Feb to 14 Feb 2014'''

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.

==== [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!

==== [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.

''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.

'''Modeling challenge event: 48 hr of prolonged northward IMF interval from 13 Feb to 14 Feb 2014'''

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.
