The generation mechanisms of EMIC waves, their effects on trapped particles, and their propagation through the M-I system are challenging topics that involve multiple GEM research areas. Despite several years of observations and improved global wave statistics, there are many unresolved questions that limit further investigation, modeling and prediction of processes in the inner magnetosphere involving EMIC waves.

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

• Yuxi Chen & Sarah Vines, Extra findings

==== [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.

We also cordially invite the audience to participate and contribute.

*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

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.

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

==== [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

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.

==== [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

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.

==== [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

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.

• 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

'''EMIC wave generation, propagation, and interactions''': Discussion leaders Alexander Drozdov and Maria Usanova

The generation mechanisms of EMIC waves, their effects on trapped particles, and their propagation through the M-I system are challenging topics that involve multiple GEM research areas. Despite several years of observations and improved global wave statistics, there are many unresolved questions that limit further investigation, modeling and prediction of processes in the inner magnetosphere involving EMIC waves. This session includes presentations and discussion that unites recent findings in different areas of EMIC wave research and identifies observations/models most needed to address unresolved questions.

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

==== [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

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

'''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.

'''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.

'''EMIC wave generation, propagation, and interactions''': Discussion leaders Alexander Drozdov and Maria Usanova

The generation mechanisms of EMIC waves, their effects on trapped particles, and their propagation through the M-I system are challenging topics that involve multiple GEM research areas. Despite several years of observations and improved global wave statistics, there are many unresolved questions that limit further investigation, modeling and prediction of processes in the inner magnetosphere involving EMIC waves. This session includes presentations and discussion that unites recent findings in different areas of EMIC wave research and identifies observations/models most needed to address unresolved questions.

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.

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

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.

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.

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.

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.

'''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.

We want to continue collaborative efforts for examining the storm periods chosen for community study:
*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.

*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!

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

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.

'''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.

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!

'''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.

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?

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.

M3-I2 Session 2 - Recap and Organize

2016-08-29T16:10:31Z

Shashazou:

Notes by Shasha Zou and the M3-I2 session leaders. Vince Eccles moderated the session.
 
'''Robert Strangeway (UCLA)''' (invited speaker): presented the importance of understanding the ion outflow physics in the terrestrial environment as well as other planets. He briefly reviewed observations from the terrestrial observations, highlighting that precipitating electron density is the single best controlling factor for ion outflow but also the hardest to parameterize in models. He then talked about several areas that progresses should be made in order to further advance our understanding of ion outflow physics.

'''Naritoshi Kitamura (ISAS/JAXA)''': presented the comparison between the GPW model results and the Akabono data. He found that the model prediction was 30-500 smaller than data.

'''Vince Eccles (USU)''': gave a brief introduction to the Generalized Polar Wind (GPM) model. He announced our AGU session “SM014: Ion upflow/outflow physics and their effects on the coupled magnetosphere-ionosphere system” and encouraged submission from the community. He requested community input for the 5 year plan for this focus group. Three subgroups have been suggested within this focus group, including ring current area, plasma sheet/substorm dynamics, as well as ionospheric boundary layer and upflow/outflow conversion.

'''Open floor discussion''':
 
Discussions during the open floor part have been focused on three topics.
 
The first is the effects of ion outflow in the magnetospheric dynamics, including key science questions and necessary methodologies. (1) Particle energy coming out from the ionosphere is important because it determines where the particle lands in the magnetosphere. Particle tracing code would be required for this effort. (2) George Kazhanov commented that anisotropic particle distribution needs kinetic approach and heat flux along magnetic field line in MHD can advance the modeling but it is difficult because of higher order moments needs another equation to close the set. (3) Bob Strangeway commented that it is important to understand “why MHD so successful?”(4) Ion outflow species are important because they determine the ring current lifetime. People working on substorms, plasma sheet will be invited to contribute to these discussions in the future.
 
The second topic discussed was the ion upflow and outflow from the ionosphere. Ionosphere as important lower altitude boundary has been recognized. Kinetic versus fluid modeling issues and energization processes have been discussed.
 
The third topic was individual storm period chosen for a focused study.

<h2>Session 1: Monday PM1 - Status, Questions, & Opportunities Magnetospheric Effects of Ionospheric Ingection</h2>
Attendence: ~45
 
Summary:
 
It has become apparent to the magnetospheric and inner magnetospheric
modeling community that model results are dramatically altered by the
presence and placement of ionospheric ions throughout the magnetosphere.
Both quiet time and storm time ionospheric upflow and outflow must be
correctly established to advance a better understanding of the
magnetosphere-ionosphere-thermosphere (M-I-T) coupled system.
This must truly be a GEM-CEDAR joint effort to address:
 
<li> the ionosphere boundary layer,
<li> the ion energization region of the polar wind
<li> the magnetospheric response to solar wind drivers and the ionospheric outflow
<li> the feedback into the lower ionosphere-thermosphere
 
Invited speakers reviewed the status of current understanding and
modeling of the effects of ionospheric ion injections on the magnetosphere.
The GEM Focus Group Chairs presented goals-overview of plans and
moderate a discussion on new in situ observational opportunities
for metric studies on plasma sheet, ring current, and substorm dynamics
to direct improvements in the current Geospace General Circulation Models (GGCMs).

<h2>Session 2: Monday PM2 - Status, Questions, & Opportunities Polar Wind and the Ionospheric Boundary</h2>
Attendence: ~35
 
Summary:
 
Invited speakers reviewed the status of current understanding and modeling
of ion upflow initiated in the ionospheric boundary. This is key for
proper M-I-T coupling. There are many open questions on ion energization
for the ionospheric polar wind that the community still must address.
To address this question properly, the spatial and temporal variations
of the ionospheric boundary (below 600km) must be defined accurately
in the polar and sub-auroral regions for appropriate comparison of PW model
results to satellite data.
 
The GEM Focus Group Chairs present goals and moderated a discussion on
the open questions of ion upflow/outflow. This effort should strive
to marshal new in situ and ground-based observational abilities with
current modeling capabilities to addressing these open issues.
CEDAR scientists are strongly encouraged to participate in this session
as a collaborative GEM-CEDAR Session on M-I-T coupling.

<h2>Session 1: Monday PM1 - Status, Questions, & Opportunities Magnetospheric Effects of Ionospheric Ingection</h2>
Attendence: ~45
 
Summary:
 
It has become apparent to the magnetospheric and inner magnetospheric
modeling community that model results are dramatically altered by the
presence and placement of ionospheric ions throughout the magnetosphere.
Both quiet time and storm time ionospheric upflow and outflow must be
correctly established to advance a better understanding of the
magnetosphere-ionosphere-thermosphere (M-I-T) coupled system.
This must truly be a GEM-CEDAR joint effort to address:
 
<li> the ionosphere boundary layer,
<li> the ion energization region of the polar wind
<li> the magnetospheric response to solar wind drivers and the ionospheric outflow
<li> the feedback into the lower ionosphere-thermosphere
 
Invited speakers reviewed the status of current understanding and
modeling of the effects of ionospheric ion injections on the magnetosphere.
The GEM Focus Group Chairs presented goals-overview of plans and
moderate a discussion on new in situ observational opportunities
for metric studies on plasma sheet, ring current, and substorm dynamics
to direct improvements in the current Geospace General Circulation Models (GGCMs).

<h2>Session 2: Monday PM2 - Status, Questions, & Opportunities Polar Wind and the Ionospheric Boundary</h2>
Attendence: ~35
 
Summary:
 
Invited speakers reviewed the status of current understanding and modeling
of ion upflow initiated in the ionospheric boundary. This is key for
proper M-I-T coupling. There are many open questions on ion energization
for the ionospheric polar wind that the community still must address.
To address this question properly, the spatial and temporal variations
of the ionospheric boundary (below 600km) must be defined accurately
in the polar and sub-auroral regions for appropriate comparison of PW model
results to satellite data.
 
The GEM Focus Group Chairs present goals and moderated a discussion on
the open questions of ion upflow/outflow. This effort should strive
to marshal new in situ and ground-based observational abilities with
current modeling capabilities to addressing these open issues.
CEDAR scientists are strongly encouraged to participate in this session
as a collaborative GEM-CEDAR Session on M-I-T coupling.

<h2>Session 2: Monday PM2 - Status, Questions, & Opportunities Polar Wind and the Ionospheric Boundary</h2>
Attendence: ~35
 
Summary:
 
Invited speakers reviewed the status of current understanding and modeling
of ion upflow initiated in the ionospheric boundary. This is key for
proper M-I-T coupling. There are many open questions on ion energization
for the ionospheric polar wind that the community still must address.
To address this question properly, the spatial and temporal variations
of the ionospheric boundary (below 600km) must be defined accurately
in the polar and sub-auroral regions for appropriate comparison of PW model
results to satellite data.
 
The GEM Focus Group Chairs present goals and moderated a discussion on
the open questions of ion upflow/outflow. This effort should strive
to marshal new in situ and ground-based observational abilities with
current modeling capabilities to addressing these open issues.
CEDAR scientists are strongly encouraged to participate in this session
as a collaborative GEM-CEDAR Session on M-I-T coupling.
