== Focus Group Proposal (2013) ==

==== Topic Description ====
This focus group aims to improve physical knowledge and modeling of the inner magnetosphere, particularly the ring current interactions and feedback with other populations in the magnetosphere (e.g., plasmasphere, radiation belt, and ionosphere). Gaps still exist in the self-consistent modeling of ring current dynamics due to complex cross-energy interactions with the radiation belts, plasmasphere, and ionosphere. While the plasmasphere and radiation belts do not contribute significantly to the inner magnetosphere current systems or directly drive electric shielding and thus are often neglected or treated crudely in ring current modeling, they still play a very important role as a driver of the dynamics of the inner magnetosphere. The plasmasphere influences the plasma wave environment that controls pitch-angle scattering rates and subsequent precipitation losses of ring current and radiation belt particles. In addition to directly altering the phase space density in the inner magnetosphere, the precipitation also enhances ionospheric conductivity and outflow rate, which modifies the inner magnetospheric electric field and composition and in turn influences the magnetic field via the modified current systems. In recent years, efforts have been made to include/improve self-consistency between the plasma and fields, and we believe the time is right to turn out focus to what has been viewed as “second order effects” in the ring current modeling community, and has certainly suffered from a paucity of insitu equatorial inner magnetospheric measurements.

Existing kinetic models (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI) use oversimplified scattering rates due to wave-particle interactions. These models can use electric fields more-orless self-consistently obtained from an ionospheric potential solver that often still treats the
conductivity non-self-consistently. Moreover, the inner magnetosphere ion composition is usually specified based on empirical models, not on first-principle physics, and therefore cannot provide event-specific influence or outcomes. These sample issues are the consequences of
overlooking the proper connection with other populations or regimes. Therefore, to further our knowledge of the ring current dynamics and the nonlinear feedback process with other populations, we desire comprehensive models that tie the ring current to other regions in a selfconsistent approach. Such a desire requires the modeling capability that takes into account physical mechanisms in different regimes as well as the interactions in between.

This focus group will foster interactions among observations, simulations, and modeling. The broad scientific goals of this focus group are, through implementation of physics in the existing models, to contribute to the physics-based understanding of (1) the mechanisms responsible for the ring current growth and decay, (2) the interactions with particles in other regions, e.g., the radiation belts and plasmasphere, and (3) the nonlinear feedback mechanisms. The main deliverable will the development of more comprehensive, full physics circulation modules, consistent with the goal of GEM program.

==== Timeliness of the Focus Group ====
Our focus group is timely for the following reasons:

* The Van Allen Probes provide extensive simultaneous high-resolution near-equatorial particle measurements over a wide energy range as well as plasma wave measurements from different inner magnetospheric components (e.g., plasmasphere, ring current and radiation belt). This enables our capability to monitor cross-energy interactions between different populations in the inner magnetosphere. In addition, the Cluster and THEMIS missions also cover a wide energy range and hence provide a great opportunity for multi-point simultaneous investigation of the inner magnetosphere.

* The recently ended “Near Earth Magnetosphere: Fields, Plasma, and Coupling” focus group (2007-2012) improved modeling capabilities in self-consistently coupling plasma with electromagnetic fields (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI). Now it is time to move forward and continue to improve modeling capabilities by stimulating the development of more comprehensive, full-physics models that could account for self-consistent crossenergy/population coupling processes. Some GGCM modules (e.g., SWMF, OpenGGCM, LFM) have already been developed to include one or more inner-magnetospheric modules, providing a necessary and important base.

* The “Plasmasphere-Magnetosphere Interaction (PMI)” focus group (2008-2013), which investigated the cold plasma population and evolution, has just ended. Our focus group would build on what was learned and apply that to couple the plasmasphere with higher energy populations, therefore continue the investigation of plasmaspheric dynamics.

==== Fit/Relevance to Existing GEM Focus Group ====
The group is intended to fill a niche within GEM that is not addressed by any active focus group but will work with and leverage results from existing GEM efforts.

* Tail-Inner Magnetosphere Interactions (2012-2016)
This focus group endeavors to investigate the physical mechanisms of tail transport modes into the inner magnetosphere while excluding the discussion on variations in the inner magnetosphere. We will use the results from this focus group as tail drivers for modeling ring
current dynamics and subsequent interactions with other inner magnetosphere populations.

* Storm-time Inner Magnetosphere-Ionosphere Convection (2013-2017)
This focus group aims to understand the coupled inner magnetosphere-ionosphere system, emphasizing the convection link. Our focus group will be complimentary to the SIMIC focus group by investigating the inner magnetosphere cross-population interactions that can alter the inner magnetosphere-ionosphere electrodynamics.

* Radiation Belt and Wave Modeling (2010-2014)
The wave-particle interaction is one important physical mechanism in the ring current and plasmasphere. We will work with the RBWM focus group to constrain physical models improved/developed under our focus group.

* The Ionospheric Source of Magnetospheric Plasma-measuring, modeling and merging into the GEM GGCM (2011-2015)
The merging of ionospheric sources into the GGCM will provide tools for better understanding the effects of heavy ions on the ring current and radiation belt dynamics, which is one of the goals of our focus group.

* Metrics and Validation (2011-2015)
Our focus group is directly related to this M&V focus group contributing to the development of more self-consistent and realistic global circulation models.

==== Goals and Deliverables ====
The goals of this proposed focus group are to provide a detailed, quantitative understanding of the coupled inner magnetosphere by including cross-energy and cross-population coupling processes. Some specific goals are:

* How do the cold plasmasphere and ring current properties influence wave-particle interactions and what are the feedback mechanisms?

These questions will be addressed through efforts such as determining the relative role of various driving mechanisms on the
ring current dynamics, developing empirical or numerical models of wave distributions in the inner magnetosphere, quantifying scattering rates by different types of waves, implementing loss rates in physical models, analyzing multi-spacecraft measurements, inferring cold plasma density, and correlating wave evolution to the dynamics of ring current and radiation belts.

* How do the cross-energy/population interactions alter the inner magnetospheric dynamics?

To address this question, modeling efforts to couple physical models from different regions are required, including coupling the plasmasphere, radiation belts, and ring current, and constructing an ionospheric conductivity model based on particle precipitation due to
magnetospheric waves. Enhanced precipitation also drives ionospheric ions into the magnetosphere, changing the content and dynamics of the ring current and radiation belts, suggesting the need to develop a self-consistent circulation link between the ionosphere and inner magnetosphere.

The main deliverable will be the development of more comprehensive, self-consistent physics-based circulation models, which is the main goal of the GEM program. They will be used for the study of ring current dynamics and interactions with the plasmasphere, radiation belts, and ionosphere. Detailed deliverables will include global wave distribution models, loss rates due to different types of waves in the ring current, plasmasphere, and radiation belts, and a dynamic module of ionospheric conductivity.

* Jichun Zhang (jichun.zhang@unh.edu) Expertise: ring current, wave-particle interaction

==== Research Area ====
Inner Magnetospheric Research Area

==== Term of Focus Group====
Five Years (2014 -- 2018)

==== Expected Activities and Challenges ====
Below are some scheduled activities in the Focus Group: (1) A statistical study of the global distributions of various plasmas waves; (2) Kinetic model improvements in wave-particle interactions, precipitation, and ionospheric conductivity modeling; (3) Model development to
couple different inner magnetosphere components; (4) Data-model comparisons with in-situ and ground-based measurement for the validation of the improved/developed models.

The challenges for modelers will be to reasonably well reproduce realistic events within different regimes. We plan to call for a series of challenges by simulating several storm events using different models with the same input, in order to improve the modeling capabilities through implementation of the physics. For example, in Year 1, we will set up a challenge study for several recent storms (e.g., those on 1 June 2013 and 2 November 2012) within the Van Allen Probes era, to compare and identify physical processes necessary for implementation in the models. In Year 2, modelers will present their capabilities with the same driving conditions and identify commonalities and discrepancies. With achievements obtained over years in both models and statistical quantities, we will repeat the challenge studies to further evaluate the model capabilities, with a potential collaboration with the Metrics and Validation Focus group.

'''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.

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

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.

• 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

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.

'''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.

== Focus Group Proposal (2013) ==

==== Topic Description ====
This focus group aims to improve physical knowledge and modeling of the inner magnetosphere, particularly the ring current interactions and feedback with other populations in the magnetosphere (e.g., plasmasphere, radiation belt, and ionosphere). Gaps still exist in the self-consistent modeling of ring current dynamics due to complex cross-energy interactions with the radiation belts, plasmasphere, and ionosphere. While the plasmasphere and radiation belts do not contribute significantly to the inner magnetosphere current systems or directly drive electric shielding and thus are often neglected or treated crudely in ring current modeling, they still play a very important role as a driver of the dynamics of the inner magnetosphere. The plasmasphere influences the plasma wave environment that controls pitch-angle scattering rates and subsequent precipitation losses of ring current and radiation belt particles. In addition to directly altering the phase space density in the inner magnetosphere, the precipitation also enhances ionospheric conductivity and outflow rate, which modifies the inner magnetospheric electric field and composition and in turn influences the magnetic field via the modified current systems. In recent years, efforts have been made to include/improve self-consistency between the plasma and fields, and we believe the time is right to turn out focus to what has been viewed as “second order effects” in the ring current modeling community, and has certainly suffered from a paucity of insitu equatorial inner magnetospheric measurements.

Existing kinetic models (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI) use oversimplified scattering rates due to wave-particle interactions. These models can use electric fields more-orless self-consistently obtained from an ionospheric potential solver that often still treats the
conductivity non-self-consistently. Moreover, the inner magnetosphere ion composition is usually specified based on empirical models, not on first-principle physics, and therefore cannot provide event-specific influence or outcomes. These sample issues are the consequences of
overlooking the proper connection with other populations or regimes. Therefore, to further our knowledge of the ring current dynamics and the nonlinear feedback process with other populations, we desire comprehensive models that tie the ring current to other regions in a selfconsistent approach. Such a desire requires the modeling capability that takes into account physical mechanisms in different regimes as well as the interactions in between.

This focus group will foster interactions among observations, simulations, and modeling. The broad scientific goals of this focus group are, through implementation of physics in the existing models, to contribute to the physics-based understanding of (1) the mechanisms responsible for the ring current growth and decay, (2) the interactions with particles in other regions, e.g., the radiation belts and plasmasphere, and (3) the nonlinear feedback mechanisms. The main deliverable will the development of more comprehensive, full physics circulation modules, consistent with the goal of GEM program.

==== Timeliness of the Focus Group ====
Our focus group is timely for the following reasons:

* The Van Allen Probes provide extensive simultaneous high-resolution near-equatorial particle measurements over a wide energy range as well as plasma wave measurements from different inner magnetospheric components (e.g., plasmasphere, ring current and radiation belt). This enables our capability to monitor cross-energy interactions between different populations in the inner magnetosphere. In addition, the Cluster and THEMIS missions also cover a wide energy range and hence provide a great opportunity for multi-point simultaneous investigation of the inner magnetosphere.

* The recently ended “Near Earth Magnetosphere: Fields, Plasma, and Coupling” focus group (2007-2012) improved modeling capabilities in self-consistently coupling plasma with electromagnetic fields (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI). Now it is time to move forward and continue to improve modeling capabilities by stimulating the development of more comprehensive, full-physics models that could account for self-consistent crossenergy/population coupling processes. Some GGCM modules (e.g., SWMF, OpenGGCM, LFM) have already been developed to include one or more inner-magnetospheric modules, providing a necessary and important base.

* The “Plasmasphere-Magnetosphere Interaction (PMI)” focus group (2008-2013), which investigated the cold plasma population and evolution, has just ended. Our focus group would build on what was learned and apply that to couple the plasmasphere with higher energy populations, therefore continue the investigation of plasmaspheric dynamics.

==== Fit/Relevance to Existing GEM Focus Group ====
The group is intended to fill a niche within GEM that is not addressed by any active focus group but will work with and leverage results from existing GEM efforts.

* Tail-Inner Magnetosphere Interactions (2012-2016)
This focus group endeavors to investigate the physical mechanisms of tail transport modes into the inner magnetosphere while excluding the discussion on variations in the inner magnetosphere. We will use the results from this focus group as tail drivers for modeling ring
current dynamics and subsequent interactions with other inner magnetosphere populations.

* Storm-time Inner Magnetosphere-Ionosphere Convection (2013-2017)
This focus group aims to understand the coupled inner magnetosphere-ionosphere system, emphasizing the convection link. Our focus group will be complimentary to the SIMIC focus group by investigating the inner magnetosphere cross-population interactions that can alter the inner magnetosphere-ionosphere electrodynamics.

* Radiation Belt and Wave Modeling (2010-2014)
The wave-particle interaction is one important physical mechanism in the ring current and plasmasphere. We will work with the RBWM focus group to constrain physical models improved/developed under our focus group.

* The Ionospheric Source of Magnetospheric Plasma-measuring, modeling and merging into the GEM GGCM (2011-2015)
The merging of ionospheric sources into the GGCM will provide tools for better understanding the effects of heavy ions on the ring current and radiation belt dynamics, which is one of the goals of our focus group.

* Metrics and Validation (2011-2015)
Our focus group is directly related to this M&V focus group contributing to the development of more self-consistent and realistic global circulation models.

==== Goals and Deliverables ====
The goals of this proposed focus group are to provide a detailed, quantitative understanding of the coupled inner magnetosphere by including cross-energy and cross-population coupling processes. Some specific goals are:

* How do the cold plasmasphere and ring current properties influence wave-particle interactions and what are the feedback mechanisms?

These questions will be addressed through efforts such as determining the relative role of various driving mechanisms on the
ring current dynamics, developing empirical or numerical models of wave distributions in the inner magnetosphere, quantifying scattering rates by different types of waves, implementing loss rates in physical models, analyzing multi-spacecraft measurements, inferring cold plasma density, and correlating wave evolution to the dynamics of ring current and radiation belts.

* How do the cross-energy/population interactions alter the inner magnetospheric dynamics?

To address this question, modeling efforts to couple physical models from different regions are required, including coupling the plasmasphere, radiation belts, and ring current, and constructing an ionospheric conductivity model based on particle precipitation due to
magnetospheric waves. Enhanced precipitation also drives ionospheric ions into the magnetosphere, changing the content and dynamics of the ring current and radiation belts, suggesting the need to develop a self-consistent circulation link between the ionosphere and inner magnetosphere.

The main deliverable will be the development of more comprehensive, self-consistent physics-based circulation models, which is the main goal of the GEM program. They will be used for the study of ring current dynamics and interactions with the plasmasphere, radiation belts, and ionosphere. Detailed deliverables will include global wave distribution models, loss rates due to different types of waves in the ring current, plasmasphere, and radiation belts, and a dynamic module of ionospheric conductivity.

* Colby Lemon (colby@aero.org) Expertise: ring current, radiation belt
* Michael Liemohn (liemohn@umich.edu) Expertise: ring current, plasmasphere, MI coupling
* Jichun Zhang (jichun.zhang@unh.edu) Expertise: ring current, wave-particle interaction

==== Research Area ====
Inner Magnetospheric Research Area

==== Term of Focus Group====
Five Years (2014 -- 2018)

==== Expected Activities and Challenges ====
Below are some scheduled activities in the Focus Group: (1) A statistical study of the global distributions of various plasmas waves; (2) Kinetic model improvements in wave-particle interactions, precipitation, and ionospheric conductivity modeling; (3) Model development to
couple different inner magnetosphere components; (4) Data-model comparisons with in-situ and ground-based measurement for the validation of the improved/developed models.

The challenges for modelers will be to reasonably well reproduce realistic events within different regimes. We plan to call for a series of challenges by simulating several storm events using different models with the same input, in order to improve the modeling capabilities through implementation of the physics. For example, in Year 1, we will set up a challenge study for several recent storms (e.g., those on 1 June 2013 and 2 November 2012) within the Van Allen Probes era, to compare and identify physical processes necessary for implementation in the models. In Year 2, modelers will present their capabilities with the same driving conditions and identify commonalities and discrepancies. With achievements obtained over years in both models and statistical quantities, we will repeat the challenge studies to further evaluate the model capabilities, with a potential collaboration with the Metrics and Validation Focus group.

== Focus Group Proposal (2013) ==

==== Topic Description ====
This focus group aims to improve physical knowledge and modeling of the inner magnetosphere, particularly the ring current interactions and feedback with other populations in the magnetosphere (e.g., plasmasphere, radiation belt, and ionosphere). Gaps still exist in the self-consistent modeling of ring current dynamics due to complex cross-energy interactions with the radiation belts, plasmasphere, and ionosphere. While the plasmasphere and radiation belts do not contribute significantly to the inner magnetosphere current systems or directly drive electric shielding and thus are often neglected or treated crudely in ring current modeling, they still play a very important role as a driver of the dynamics of the inner magnetosphere. The plasmasphere influences the plasma wave environment that controls pitch-angle scattering rates and subsequent precipitation losses of ring current and radiation belt particles. In addition to directly altering the phase space density in the inner magnetosphere, the precipitation also enhances ionospheric conductivity and outflow rate, which modifies the inner magnetospheric electric field and composition and in turn influences the magnetic field via the modified current systems. In recent years, efforts have been made to include/improve self-consistency between the plasma and fields, and we believe the time is right to turn out focus to what has been viewed as “second order effects” in the ring current modeling community, and has certainly suffered from a paucity of insitu equatorial inner magnetospheric measurements.

Existing kinetic models (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI) use oversimplified scattering rates due to wave-particle interactions. These models can use electric fields more-orless self-consistently obtained from an ionospheric potential solver that often still treats the
conductivity non-self-consistently. Moreover, the inner magnetosphere ion composition is usually specified based on empirical models, not on first-principle physics, and therefore cannot provide event-specific influence or outcomes. These sample issues are the consequences of
overlooking the proper connection with other populations or regimes. Therefore, to further our knowledge of the ring current dynamics and the nonlinear feedback process with other populations, we desire comprehensive models that tie the ring current to other regions in a selfconsistent approach. Such a desire requires the modeling capability that takes into account physical mechanisms in different regimes as well as the interactions in between.

This focus group will foster interactions among observations, simulations, and modeling. The broad scientific goals of this focus group are, through implementation of physics in the existing models, to contribute to the physics-based understanding of (1) the mechanisms responsible for the ring current growth and decay, (2) the interactions with particles in other regions, e.g., the radiation belts and plasmasphere, and (3) the nonlinear feedback mechanisms. The main deliverable will the development of more comprehensive, full physics circulation modules, consistent with the goal of GEM program.

==== Timeliness of the Focus Group ====
Our focus group is timely for the following reasons:

* The Van Allen Probes provide extensive simultaneous high-resolution near-equatorial particle measurements over a wide energy range as well as plasma wave measurements from different inner magnetospheric components (e.g., plasmasphere, ring current and radiation belt). This enables our capability to monitor cross-energy interactions between different populations in the inner magnetosphere. In addition, the Cluster and THEMIS missions also cover a wide energy range and hence provide a great opportunity for multi-point simultaneous investigation of the inner magnetosphere.

* The recently ended “Near Earth Magnetosphere: Fields, Plasma, and Coupling” focus group (2007-2012) improved modeling capabilities in self-consistently coupling plasma with electromagnetic fields (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI). Now it is time to move forward and continue to improve modeling capabilities by stimulating the development of more comprehensive, full-physics models that could account for self-consistent crossenergy/population coupling processes. Some GGCM modules (e.g., SWMF, OpenGGCM, LFM) have already been developed to include one or more inner-magnetospheric modules, providing a necessary and important base.

* The “Plasmasphere-Magnetosphere Interaction (PMI)” focus group (2008-2013), which investigated the cold plasma population and evolution, has just ended. Our focus group would build on what was learned and apply that to couple the plasmasphere with higher energy populations, therefore continue the investigation of plasmaspheric dynamics.

==== Fit/Relevance to Existing GEM Focus Group ====
The group is intended to fill a niche within GEM that is not addressed by any active focus group but will work with and leverage results from existing GEM efforts.

* Tail-Inner Magnetosphere Interactions (2012-2016)
This focus group endeavors to investigate the physical mechanisms of tail transport modes into the inner magnetosphere while excluding the discussion on variations in the inner magnetosphere. We will use the results from this focus group as tail drivers for modeling ring
current dynamics and subsequent interactions with other inner magnetosphere populations.

* Storm-time Inner Magnetosphere-Ionosphere Convection (2013-2017)
This focus group aims to understand the coupled inner magnetosphere-ionosphere system, emphasizing the convection link. Our focus group will be complimentary to the SIMIC focus group by investigating the inner magnetosphere cross-population interactions that can alter the inner magnetosphere-ionosphere electrodynamics.

* Radiation Belt and Wave Modeling (2010-2014)
The wave-particle interaction is one important physical mechanism in the ring current and plasmasphere. We will work with the RBWM focus group to constrain physical models improved/developed under our focus group.

* The Ionospheric Source of Magnetospheric Plasma-measuring, modeling and merging into the GEM GGCM (2011-2015)
The merging of ionospheric sources into the GGCM will provide tools for better understanding the effects of heavy ions on the ring current and radiation belt dynamics, which is one of the goals of our focus group.

* Metrics and Validation (2011-2015)
Our focus group is directly related to this M&V focus group contributing to the development of more self-consistent and realistic global circulation models.

==== Goals and Deliverables ====
The goals of this proposed focus group are to provide a detailed, quantitative understanding of the coupled inner magnetosphere by including cross-energy and cross-population coupling processes. Some specific goals are:

* How do the cold plasmasphere and ring current properties influence wave-particle interactions and what are the feedback mechanisms?

These questions will be addressed through efforts such as determining the relative role of various driving mechanisms on the
ring current dynamics, developing empirical or numerical models of wave distributions in the inner magnetosphere, quantifying scattering rates by different types of waves, implementing loss rates in physical models, analyzing multi-spacecraft measurements, inferring cold plasma density, and correlating wave evolution to the dynamics of ring current and radiation belts.

* How do the cross-energy/population interactions alter the inner magnetospheric dynamics?

To address this question, modeling efforts to couple physical models from different regions are required, including coupling the plasmasphere, radiation belts, and ring current, and constructing an ionospheric conductivity model based on particle precipitation due to
magnetospheric waves. Enhanced precipitation also drives ionospheric ions into the magnetosphere, changing the content and dynamics of the ring current and radiation belts, suggesting the need to develop a self-consistent circulation link between the ionosphere and inner magnetosphere.

The main deliverable will be the development of more comprehensive, self-consistent physics-based circulation models, which is the main goal of the GEM program. They will be used for the study of ring current dynamics and interactions with the plasmasphere, radiation belts, and ionosphere. Detailed deliverables will include global wave distribution models, loss rates due to different types of waves in the ring current, plasmasphere, and radiation belts, and a dynamic module of ionospheric conductivity.

==== Co-Chairs ====
* Yiqun Yu (yiqun@lanl.gov) Expertise: MHD and kinetic modeling, MI coupling
* Colby Lemon (colby@aero.org) Expertise: ring current, radiation belt
* Michael Liemohn (liemohn@umich.edu) Expertise: ring current, plasmasphere, MI coupling
* Jichun Zhang (jichun.zhang@unh.edu) Expertise: ring current, wave-particle interaction

==== Research Area ====
Inner Magnetospheric Research Area

==== Term of Focus Group====
Five Years (2014 -- 2018)

==== Expected Activities and Challenges ====
Below are some scheduled activities in the Focus Group: (1) A statistical study of the global distributions of various plasmas waves; (2) Kinetic model improvements in wave-particle interactions, precipitation, and ionospheric conductivity modeling; (3) Model development to
couple different inner magnetosphere components; (4) Data-model comparisons with in-situ and ground-based measurement for the validation of the improved/developed models.

The challenges for modelers will be to reasonably well reproduce realistic events within different regimes. We plan to call for a series of challenges by simulating several storm events using different models with the same input, in order to improve the modeling capabilities through implementation of the physics. For example, in Year 1, we will set up a challenge study for several recent storms (e.g., those on 1 June 2013 and 2 November 2012) within the Van Allen Probes era, to compare and identify physical processes necessary for implementation in the models. In Year 2, modelers will present their capabilities with the same driving conditions and identify commonalities and discrepancies. With achievements obtained over years in both models and statistical quantities, we will repeat the challenge studies to further evaluate the model capabilities, with a potential collaboration with the Metrics and Validation Focus group.

Our focus group is directly related to this M&V focus group contributing to the development of more self-consistent and realistic global circulation models.

==== Goals and Deliverables ====
The goals of this proposed focus group are to provide a detailed, quantitative understanding of the coupled inner magnetosphere by including cross-energy and cross-population coupling processes. Some specific goals are:

* How do the cold plasmasphere and ring current properties influence wave-particle interactions and what are the feedback mechanisms?

These questions will be addressed through efforts such as determining the relative role of various driving mechanisms on the
ring current dynamics, developing empirical or numerical models of wave distributions in the inner magnetosphere, quantifying scattering rates by different types of waves, implementing loss rates in physical models, analyzing multi-spacecraft measurements, inferring cold plasma density, and correlating wave evolution to the dynamics of ring current and radiation belts.

* How do the cross-energy/population interactions alter the inner magnetospheric dynamics?

To address this question, modeling efforts to couple physical models from different regions are required, including coupling the plasmasphere, radiation belts, and ring current, and constructing an ionospheric conductivity model based on particle precipitation due to
magnetospheric waves. Enhanced precipitation also drives ionospheric ions into the magnetosphere, changing the content and dynamics of the ring current and radiation belts, suggesting the need to develop a self-consistent circulation link between the ionosphere and inner magnetosphere.

The main deliverable will be the development of more comprehensive, self-consistent physics-based circulation models, which is the main goal of the GEM program. They will be used for the study of ring current dynamics and interactions with the plasmasphere, radiation belts, and ionosphere. Detailed deliverables will include global wave distribution models, loss rates due to different types of waves in the ring current, plasmasphere, and radiation belts, and a dynamic module of ionospheric conductivity.

==== Research Area ====
Inner Magnetospheric Research Area

==== Term of Focus Group====
Five Years (2014 -- 2018)

==== Expected Activities and Challenges ====
Below are some scheduled activities in the Focus Group: (1) A statistical study of the global distributions of various plasmas waves; (2) Kinetic model improvements in wave-particle interactions, precipitation, and ionospheric conductivity modeling; (3) Model development to
couple different inner magnetosphere components; (4) Data-model comparisons with in-situ and ground-based measurement for the validation of the improved/developed models.

The challenges for modelers will be to reasonably well reproduce realistic events within different regimes. We plan to call for a series of challenges by simulating several storm events using different models with the same input, in order to improve the modeling capabilities through implementation of the physics. For example, in Year 1, we will set up a challenge study for several recent storms (e.g., those on 1 June 2013 and 2 November 2012) within the Van Allen Probes era, to compare and identify physical processes necessary for implementation in the models. In Year 2, modelers will present their capabilities with the same driving conditions and identify commonalities and discrepancies. With achievements obtained over years in both models and statistical quantities, we will repeat the challenge studies to further evaluate the model capabilities, with a potential collaboration with the Metrics and Validation Focus group.

== Focus Group Proposal (2013) ==

==== Topic Description ====
This focus group aims to improve physical knowledge and modeling of the inner magnetosphere, particularly the ring current interactions and feedback with other populations in the magnetosphere (e.g., plasmasphere, radiation belt, and ionosphere). Gaps still exist in the self-consistent modeling of ring current dynamics due to complex cross-energy interactions with the radiation belts, plasmasphere, and ionosphere. While the plasmasphere and radiation belts do not contribute significantly to the inner magnetosphere current systems or directly drive electric shielding and thus are often neglected or treated crudely in ring current modeling, they still play a very important role as a driver of the dynamics of the inner magnetosphere. The plasmasphere influences the plasma wave environment that controls pitch-angle scattering rates and subsequent precipitation losses of ring current and radiation belt particles. In addition to directly altering the phase space density in the inner magnetosphere, the precipitation also enhances ionospheric conductivity and outflow rate, which modifies the inner magnetospheric electric field and composition and in turn influences the magnetic field via the modified current systems. In recent years, efforts have been made to include/improve self-consistency between the plasma and fields, and we believe the time is right to turn out focus to what has been viewed as “second order effects” in the ring current modeling community, and has certainly suffered from a paucity of insitu equatorial inner magnetospheric measurements.

Existing kinetic models (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI) use oversimplified scattering rates due to wave-particle interactions. These models can use electric fields more-orless self-consistently obtained from an ionospheric potential solver that often still treats the
conductivity non-self-consistently. Moreover, the inner magnetosphere ion composition is usually specified based on empirical models, not on first-principle physics, and therefore cannot provide event-specific influence or outcomes. These sample issues are the consequences of
overlooking the proper connection with other populations or regimes. Therefore, to further our knowledge of the ring current dynamics and the nonlinear feedback process with other populations, we desire comprehensive models that tie the ring current to other regions in a selfconsistent approach. Such a desire requires the modeling capability that takes into account physical mechanisms in different regimes as well as the interactions in between.

This focus group will foster interactions among observations, simulations, and modeling. The broad scientific goals of this focus group are, through implementation of physics in the existing models, to contribute to the physics-based understanding of (1) the mechanisms responsible for the ring current growth and decay, (2) the interactions with particles in other regions, e.g., the radiation belts and plasmasphere, and (3) the nonlinear feedback mechanisms. The main deliverable will the development of more comprehensive, full physics circulation modules, consistent with the goal of GEM program.

==== Timeliness of the Focus Group ====
Our focus group is timely for the following reasons:

* The Van Allen Probes provide extensive simultaneous high-resolution near-equatorial particle measurements over a wide energy range as well as plasma wave measurements from different inner magnetospheric components (e.g., plasmasphere, ring current and radiation belt). This enables our capability to monitor cross-energy interactions between different populations in the inner magnetosphere. In addition, the Cluster and THEMIS missions also cover a wide energy range and hence provide a great opportunity for multi-point simultaneous investigation of the inner magnetosphere.

* The recently ended “Near Earth Magnetosphere: Fields, Plasma, and Coupling” focus group (2007-2012) improved modeling capabilities in self-consistently coupling plasma with electromagnetic fields (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI). Now it is time to move forward and continue to improve modeling capabilities by stimulating the development of more comprehensive, full-physics models that could account for self-consistent crossenergy/population coupling processes. Some GGCM modules (e.g., SWMF, OpenGGCM, LFM) have already been developed to include one or more inner-magnetospheric modules, providing a necessary and important base.

* The “Plasmasphere-Magnetosphere Interaction (PMI)” focus group (2008-2013), which investigated the cold plasma population and evolution, has just ended. Our focus group would build on what was learned and apply that to couple the plasmasphere with higher energy populations, therefore continue the investigation of plasmaspheric dynamics.

==== Fit/Relevance to Existing GEM Focus Group ====
The group is intended to fill a niche within GEM that is not addressed by any active focus group but will work with and leverage results from existing GEM efforts.

* Tail-Inner Magnetosphere Interactions (2012-2016)
This focus group endeavors to investigate the physical mechanisms of tail transport modes into the inner magnetosphere while excluding the discussion on variations in the inner magnetosphere. We will use the results from this focus group as tail drivers for modeling ring
current dynamics and subsequent interactions with other inner magnetosphere populations.

* Storm-time Inner Magnetosphere-Ionosphere Convection (2013-2017)
This focus group aims to understand the coupled inner magnetosphere-ionosphere system, emphasizing the convection link. Our focus group will be complimentary to the SIMIC focus group by investigating the inner magnetosphere cross-population interactions that can alter the inner magnetosphere-ionosphere electrodynamics.

* Radiation Belt and Wave Modeling (2010-2014)
The wave-particle interaction is one important physical mechanism in the ring current and plasmasphere. We will work with the RBWM focus group to constrain physical models improved/developed under our focus group.

* The Ionospheric Source of Magnetospheric Plasma-measuring, modeling and merging into the GEM GGCM (2011-2015)
The merging of ionospheric sources into the GGCM will provide tools for better understanding the effects of heavy ions on the ring current and radiation belt dynamics, which is one of the goals of our focus group.

* Metrics and Validation (2011-2015)
Our focus group is directly related to this M&V focus group contributing to the development of more self-consistent and realistic global circulation models.

==== Goals and Deliverables ====
The goals of this proposed focus group are to provide a detailed, quantitative understanding of the coupled inner magnetosphere by including cross-energy and cross-population coupling processes. Some specific goals are:

* How do the cold plasmasphere and ring current properties influence wave-particle interactions and what are the feedback mechanisms?

These questions will be addressed through efforts such as determining the relative role of various driving mechanisms on the
ring current dynamics, developing empirical or numerical models of wave distributions in the inner magnetosphere, quantifying scattering rates by different types of waves, implementing loss rates in physical models, analyzing multi-spacecraft measurements, inferring cold plasma density, and correlating wave evolution to the dynamics of ring current and radiation belts.

* How do the cross-energy/population interactions alter the inner magnetospheric dynamics?

To address this question, modeling efforts to couple physical models from different regions are required, including coupling the plasmasphere, radiation belts, and ring current, and constructing an ionospheric conductivity model based on particle precipitation due to
magnetospheric waves. Enhanced precipitation also drives ionospheric ions into the magnetosphere, changing the content and dynamics of the ring current and radiation belts, suggesting the need to develop a self-consistent circulation link between the ionosphere and inner magnetosphere.

The main deliverable will be the development of more comprehensive, self-consistent physics-based circulation models, which is the main goal of the GEM program. They will be used for the study of ring current dynamics and interactions with the plasmasphere, radiation belts, and ionosphere. Detailed deliverables will include global wave distribution models, loss rates due to different types of waves in the ring current, plasmasphere, and radiation belts, and a dynamic module of ionospheric conductivity.

== Focus Group Proposal (2013) ==

==== Topic Description ====
This focus group aims to improve physical knowledge and modeling of the inner magnetosphere, particularly the ring current interactions and feedback with other populations in the magnetosphere (e.g., plasmasphere, radiation belt, and ionosphere). Gaps still exist in the self-consistent modeling of ring current dynamics due to complex cross-energy interactions with the radiation belts, plasmasphere, and ionosphere. While the plasmasphere and radiation belts do not contribute significantly to the inner magnetosphere current systems or directly drive electric shielding and thus are often neglected or treated crudely in ring current modeling, they still play a very important role as a driver of the dynamics of the inner magnetosphere. The plasmasphere influences the plasma wave environment that controls pitch-angle scattering rates and subsequent precipitation losses of ring current and radiation belt particles. In addition to directly altering the phase space density in the inner magnetosphere, the precipitation also enhances ionospheric conductivity and outflow rate, which modifies the inner magnetospheric electric field and composition and in turn influences the magnetic field via the modified current systems. In recent years, efforts have been made to include/improve self-consistency between the plasma and fields, and we believe the time is right to turn out focus to what has been viewed as “second order effects” in the ring current modeling community, and has certainly suffered from a paucity of insitu equatorial inner magnetospheric measurements.

Existing kinetic models (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI) use oversimplified scattering rates due to wave-particle interactions. These models can use electric fields more-orless self-consistently obtained from an ionospheric potential solver that often still treats the
conductivity non-self-consistently. Moreover, the inner magnetosphere ion composition is usually specified based on empirical models, not on first-principle physics, and therefore cannot provide event-specific influence or outcomes. These sample issues are the consequences of
overlooking the proper connection with other populations or regimes. Therefore, to further our knowledge of the ring current dynamics and the nonlinear feedback process with other populations, we desire comprehensive models that tie the ring current to other regions in a selfconsistent approach. Such a desire requires the modeling capability that takes into account physical mechanisms in different regimes as well as the interactions in between.

This focus group will foster interactions among observations, simulations, and modeling. The broad scientific goals of this focus group are, through implementation of physics in the existing models, to contribute to the physics-based understanding of (1) the mechanisms responsible for the ring current growth and decay, (2) the interactions with particles in other regions, e.g., the radiation belts and plasmasphere, and (3) the nonlinear feedback mechanisms. The main deliverable will the development of more comprehensive, full physics circulation modules, consistent with the goal of GEM program.

==== Timeliness of the Focus Group ====
Our focus group is timely for the following reasons:

* The Van Allen Probes provide extensive simultaneous high-resolution near-equatorial particle measurements over a wide energy range as well as plasma wave measurements from different inner magnetospheric components (e.g., plasmasphere, ring current and radiation belt). This enables our capability to monitor cross-energy interactions between different populations in the inner magnetosphere. In addition, the Cluster and THEMIS missions also cover a wide energy range and hence provide a great opportunity for multi-point simultaneous investigation of the inner magnetosphere.

* The recently ended “Near Earth Magnetosphere: Fields, Plasma, and Coupling” focus group (2007-2012) improved modeling capabilities in self-consistently coupling plasma with electromagnetic fields (e.g., RAM-SCB, RCM, RCM-E, CRCM, HEIDI). Now it is time to move forward and continue to improve modeling capabilities by stimulating the development of more comprehensive, full-physics models that could account for self-consistent crossenergy/population coupling processes. Some GGCM modules (e.g., SWMF, OpenGGCM, LFM) have already been developed to include one or more inner-magnetospheric modules, providing a necessary and important base.

* The “Plasmasphere-Magnetosphere Interaction (PMI)” focus group (2008-2013), which investigated the cold plasma population and evolution, has just ended. Our focus group would build on what was learned and apply that to couple the plasmasphere with higher energy populations, therefore continue the investigation of plasmaspheric dynamics.

==== Fit/Relevance to Existing GEM Focus Group ====
The group is intended to fill a niche within GEM that is not addressed by any active focus group but will work with and leverage results from existing GEM efforts.

* Tail-Inner Magnetosphere Interactions (2012-2016)
This focus group endeavors to investigate the physical mechanisms of tail transport modes into the inner magnetosphere while excluding the discussion on variations in the inner magnetosphere. We will use the results from this focus group as tail drivers for modeling ring
current dynamics and subsequent interactions with other inner magnetosphere populations.

* Storm-time Inner Magnetosphere-Ionosphere Convection (2013-2017)
This focus group aims to understand the coupled inner magnetosphere-ionosphere system, emphasizing the convection link. Our focus group will be complimentary to the SIMIC focus group by investigating the inner magnetosphere cross-population interactions that can alter the inner magnetosphere-ionosphere electrodynamics.

* Radiation Belt and Wave Modeling (2010-2014)
The wave-particle interaction is one important physical mechanism in the ring current and plasmasphere. We will work with the RBWM focus group to constrain physical models improved/developed under our focus group.

* The Ionospheric Source of Magnetospheric Plasma-measuring, modeling and merging into the GEM GGCM (2011-2015)
The merging of ionospheric sources into the GGCM will provide tools for better understanding the effects of heavy ions on the ring current and radiation belt dynamics, which is one of the goals of our focus group.

* Metrics and Validation (2011-2015)
Our focus group is directly related to this M&V focus group contributing to the development of more self-consistent and realistic global circulation models.

==== Goals and Deliverables ====
The goals of this proposed focus group are to provide a detailed, quantitative understanding of the coupled inner magnetosphere by including cross-energy and cross-population coupling processes. Some specific goals are:

* How do the cold plasmasphere and ring current properties influence wave-particle interactions and what are the feedback mechanisms?

These questions will be addressed through efforts such as determining the relative role of various driving mechanisms on the
ring current dynamics, developing empirical or numerical models of wave distributions in the inner magnetosphere, quantifying scattering rates by different types of waves, implementing loss rates in physical models, analyzing multi-spacecraft measurements, inferring cold plasma density, and correlating wave evolution to the dynamics of ring current and radiation belts.

* How do the cross-energy/population interactions alter the inner magnetospheric dynamics?

To address this question, modeling efforts to couple physical models from different regions are required, including coupling the plasmasphere, radiation belts, and ring current, and constructing an ionospheric conductivity model based on particle precipitation due to
magnetospheric waves. Enhanced precipitation also drives ionospheric ions into the magnetosphere, changing the content and dynamics of the ring current and radiation belts, suggesting the need to develop a self-consistent circulation link between the ionosphere and inner magnetosphere.

The main deliverable will be the development of more comprehensive, self-consistent physics-based circulation models, which is the main goal of the GEM program. They will be used for the study of ring current dynamics and interactions with the plasmasphere, radiation belts, and ionosphere. Detailed deliverables will include global wave distribution models, loss rates due to different types of waves in the ring current, plasmasphere, and radiation belts, and a dynamic module of ionospheric conductivity.

==== Co-Chairs ====

* Colby Lemon (colby@aero.org) Expertise: ring current, radiation belt
* Michael Liemohn (liemohn@umich.edu) Expertise: ring current, plasmasphere, MI coupling
* Jichun Zhang (jichun.zhang@unh.edu) Expertise: ring current, wave-particle interaction

==== Research Area ====
Inner Magnetospheric Research Area

==== Term of Focus Group====
Five Years (2014 -- 2018)

==== Expected Activities and Challenges ====
Below are some scheduled activities in the Focus Group: (1) A statistical study of the global distributions of various plasmas waves; (2) Kinetic model improvements in wave-particle interactions, precipitation, and ionospheric conductivity modeling; (3) Model development to
couple different inner magnetosphere components; (4) Data-model comparisons with in-situ and ground-based measurement for the validation of the improved/developed models.

The challenges for modelers will be to reasonably well reproduce realistic events within different regimes. We plan to call for a series of challenges by simulating several storm events using different models with the same input, in order to improve the modeling capabilities through implementation of the physics. For example, in Year 1, we will set up a challenge study for several recent storms (e.g., those on 1 June 2013 and 2 November 2012) within the Van Allen Probes era, to compare and identify physical processes necessary for implementation in the models. In Year 2, modelers will present their capabilities with the same driving conditions and identify commonalities and discrepancies. With achievements obtained over years in both models and statistical quantities, we will repeat the challenge studies to further evaluate the model capabilities, with a potential collaboration with the Metrics and Validation Focus group.
