== 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.

== 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.

==== 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

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.

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.

To the members of the RBW GEM focus group,

Our focus group is coming to an end and we would like to summarize our progress and the work that we have done over the last few years.

Our sessions attracted a lot of interest, and we believe that the most important result of our work are the discussions held during our sessions. Our discussions helped us focus on the most important scientific topics, and provided a forum for the exchange of ideas. Our particle and wave challenges set up a framework for the future validation of models comparison of models with observation and improved our understanding of physical processes in the radiation belts. To summarize the efforts of the RBW FG, we would like to collect the titles of the publications that are related to RBW FG work.

We seek observational and theory/simulation speakers who study physical mechanisms on how magnetosheath (MSH) properties impact and drive magnetospheric (MSP) plasma and field properties. For example, the specific entropy from magnetosheath into magnetosphere increases by orders of magnitude but the physical mechanisms responsible for this are not clearly understood. Talks that discuss the origins of non-adiabatic plasma heating via magnetopause or magnetospheric plasma processes are encouraged:

1. Are there some specific solar wind and magnetosheath conditions where the specific entropy increase is further enhanced or reduced?
2. How do the electron and ion temperature and specific entropy ratios change from magnetosheath into magnetosphere (dayside, inner magnetosphere and magnetotail) and what physical mechanisms in the magnetosheath, magnetopause and magnetosphere contribute to maintaining or changing these ratios during different SW conditions?
3. Can we identify similarities and differences in these heating processes in the magnetosheath-magnetosphere system from those in solar corona?

To enable adequate discussion we limit each speaker to 3-5 slides. Send your contribution idea to session organizers by 7th of June:

'''Session 3''' (Friday, 10:30-12:15)

We seek observational and theory/simulation speakers (3-5 slides/speaker) who have recent new results on the topics related to the magnetosheath FG proposal and which are not addressed in the joint sessions (see above).
Also, as this is the last FG meeting, we ask previous GEM magnetosheath FG participants to send a 2-3 slide summary of their magnetosheath work and list of publications addressing any of the topics listed in GEM FG proposal and/or challenge related to dawn-dusk asymmetries. A discussion of a possible magnetosheath FG review paper is also presented. Accomplishments of the magnetosheath FG will be presented at Friday afternoon summary session.

'''Session 1:''' Model Uncertainty: Dealing with uncertain physical processes and boundary conditions.

In this session we solicit contributions discussing how model uncertainties and uncertain boundary conditions affect model results and validation. Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers).

We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are:

# Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?
# What model assumptions affect the model predictions significantly and lead to differences between models?
# How does the magnetopause change during extreme events
# How sensitive is model performance to changes of the boundary conditions?
# Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?

We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.

'''Session 2:''' Validating Models under Extreme Geomagnetic Conditions.

Extreme events in the geospace environment are among the most interesting scientifically as well as important for their space weather consequences. The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events. Contributions to these and related issues are welcome.

''Conveners: Rick Chappell <rick.chappell [at] vanderbilt.edu>, Bob Schunk and Dan Welling''

Plans are taking shape for the upcoming GEM meeting in June and we
would like to invite you to participate in the activities of the
Ionospheric Source of Magnetospheric Plasma focus group. This group
has as its goal to improve the understanding of the role of the
ionospheric outflow source by (1) refining outflow modeling through
comparison with measurements, (2) adjusting the outflow modeling to
become a compatible input to the magnetospheric Geospace Global
Circulation Models (GGCM), (3) comparing magnetospheric modeling
results with satellite and ground-based measurements and (4) examining
ways in which the dynamic magnetosphere can couple back to influence
the original ionospheric outflow.

We are following a schedule of cooperative modeling and measurement
activities that was planned by the focus group attendees at the
Snowmass Meeting last June and that has included presentations at the
mini-GEM meeting at the AGU meeting in December and the AGU Chapman
conference at Yosemite in February. We have begun working together on
both an idealized magnetic storm period and on the first real storm
event (September 27 to October 4, 2002).

Generalized polar wind outflow modeling at USU has been completed for
the idealized storm and is available to the community to compare with
other outflow models and to use as input for magnetospheric models.
The GPW outflow model is being run now for the first real storm period
and initial results will be available at the June GEM meeting.
Contact Bob Schunk for model output details (rws4405[at]yahoo.com)
Upstream solar wind drivers are also available for these two storms
from Dan Welling at UM (dwelling[at]umich.edu).

We have planned the following four sessions for the June GEM meeting
and would like for you to suggest topics that you would like to
present in the sessions.

'''Session 1'''—Merged Model and Measurements of Storm Dynamics 1—June 17, 10:30 am
This session will be an opportunity for ionospheric outflow,
magnetospheric and merged M-I modelers to present results related to
the idealized storm as well as the first real storm event.
Comparisons between modeling approaches are encouraged as well as the
presentation and inter-comparison of relevant measurements for each of
the storms.

'''Session 2'''—Merged Model and Measurements of Storm Dynamics 2—June 17, 1:30 pm
This session will be a continuation of session 1 with an
emphasis on the real storm event. Presentation of specific satellite
and ground-based data during the selected first real storm event will
be encouraged so that comparison with the evolving merged models of
this storm can be made.

'''Session 3'''—General Contributions in Measurements & Modeling Including the Plasmasphere—June 17, 3:30 pm
This session will cover a variety of topics related to
developing the merged ionosphere-magnetosphere models and testing them
with measurements made during the storm periods. We are also
requesting presentations related to plasmasphere modeling and
measurement.

'''Session 4'''—Planning Session—June 18, 10:30 am
This will be an open discussion to update the coordinated
modeling and measurement research that was initiated at the 2013 GEM
meeting. We will assess our progress and develop new approaches as
necessary to continue the active cooperative research that has begun.
We will also select the second storm event to be modeled for
comparison with measurements.

Please send your topics and suggestions to Rick Chappell by May 12,
2014 at rick.chappell [at] vanderbilt.edu.

We look forward to seeing you at the GEM meeting in June.

''Conveners: Paul Cassak <Paul.Cassak [at] mail.wvu.edu>, Andrei Runov <arunov [at] igpp.ucla.edu>, and Homa Karimabadi <homakar [at] gmail.com>''

We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting.

The format for each is to have two speakers set the scene on a particular topic. Others are encouraged to contribute to the discussion and put up a slide or two as relevant. Half of one session will be for general contributions consisting of no more than 4 slides - 1 for intro to acclimate graduate students, and no more than 3 on your topic. If you would like to be considered for one of the general contributions, please email Paul.Cassak [at] mail.wvu.edu with your topic. We will try to accommodate as many of the requests for talks as possible. We strongly encourage everyone wishing to present to sign up to give a poster to ensure you are able to present more than a few slides. Please let one of the focus group chairs know if you have any comments or questions.

The dates, times, locations, and summaries for each session are described here:

'''Monday 6/16, 10:30am-12:15pm, Ports Ballroom I-III'''
''First half'' - "What controls the rate of dayside reconnection?"
Scene-setters - Joe Borovsky and Ramon Lopez
Science - It has long been thought that the reconnection rate at the dayside is controlled by the electric field in the solar wind. Recent observations that geomagnetic indices are affected by plasmaspheric drainage plumes called this into question, suggesting local control of the reconnection rate. This session will tackle this fundamental question of importance to solar wind-magnetospheric coupling. We will hear from proponents on each side and discuss how future progress will be made on these questions.

''Second half'' - "General Contributions"
Scene-setters - None
Science - Please consider contributing a few slides on any topic on reconnection (provided it is GEM relevant). Observations, modeling, and theory presentations are encouraged. Again, since we are only leaving 45 minutes for this session, all potential contributors are encouraged to also sign up to give a poster.

'''Monday 6/16, 1:30pm-3:00pm, Ports Ballroom I-III'''
''First half'' - "What determines the cross-tail scale of reconnection jets?"
Scene-setters - Phil Pritchett and Jiang Liu
Science - Multi-satellite missions have made it accessible to study the three-dimensional structure of reconnection in the magnetotail. Observationally, what is the characteristic length in the out-of-plane direction of the reconnection events? Theoretically, what physically sets this length? These topics will be discussed in this session.

''Second half'' - "How is magnetotail reconnection modulated by dayside reconnection? What is the nature of magnetotail reconnection onset and transients?"
Scene-setters - Toshi Nishimura and Joachim Birn
Science - Reconnection in the magnetotail onsets abruptly, and is often bursty. It can further be modulated due to time-dependent phenomena on the dayside. This session will discuss how reconnection in the magnetotail responds to modulation from the dayside and what causes reconnection onset and transients in the magnetotail. Observational and theoretical/modeling considerations will be discussed.

'''Monday 6/16, 3:30pm-5:00pm, Ports Ballroom I-III (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)'''
Scene-setters - Misha Sitnov and Andrei Runov
Science - This joint session will focus on the relationship between bursty bulk flows/dipolarization fronts and reconnection, both from the observational and theoretical/modeling perspective. In many ways, this is a continuation of the1:30-3:00 session, but additional attention will be paid to
the ramifications on the inner magnetosphere.
Please let Paul.Cassak [at] mail.wvu.edu or toffo [at] rice.edu know if you are interested in contributing.

'''Thursday 6/19, 3:30pm-5:00pm, Ports Ballroom I-III (Joint with "The Magnetosheath" Focus Group)'''
Scene-setters - TBD
Science - We seek observational and theory/simulation speakers who study
1. the consequences of foreshock and magnetosheath turbulence on dayside reconnection,
2. the effects of velocity shear and plasma beta on dayside reconnection,
3. plasma heating in magnetosheath reconnection.
Please send your contribution ideas to session organizers by the 6th of June(any of the above organizers or petrinec [at] lmsal.com or nykyrik [at] erau.edu)

We look forward to seeing you at the sessions! Please let the organizers (Paul.Cassak [at] mail.wvu.edu) know about contributions by Friday, June 6.

''Conveners: Joseph Baker, Stan Sazykin, Mike Ruohoniemi, Peter Chi, Mark Engebretson''

We are asking for your participation in the SIMIC (Storm-Time Inner Magnetosphere-Ionosphere Convection) focus group sessions at the upcoming GEM workshop. The SIMIC Focus Group will hold 3 breakout sessions on Monday June 16; one of these session will be joint with the new "Systems Science" focus group and focus on the shielding phenomenon.

We invite brief presentations on observations and modeling that examine the coupled dynamics of the inner magnetosphere and ionosphere during geomagnetic storms. Some examples of relevant parameters of interest include: plasma distributions, magnetic topology, convection electric fields, and current systems.

For this year's workshop, we are looking for presentations that:
(i) address the specific question of shielding and penetration electric fields, or
(ii) highlight other outstanding science questions relevant to the focus group.

More details about the SIMIC Focus Group can be found at:

http://gem.epss.ucla.edu/mediawikiwiki/index.php/FG:_Storm-Time_Inner_Magnetosphere-Ionosphere_Convection

If you would like to give a SIMIC presentation please email Joseph Baker <bakerjb [at] vt.edu> and Stan Sazykin <sazykin [at] rice.edu> providing: (i) a working title for your talk, (ii) the specific science question(s) you will be addressing, and, (iii) dates and times for any event periods that will be highlighted.

For the new "Geospace Systems Science" Focus group, two working
sessions will be held at the GEM Summer Workshop in Portsmouth, VA.
This is a call for research and participation in those two sessions.

'''Session 1:''' "Timescales, Time Lags, and Feedback Loops in the M-I
System". The first purpose of this session is to identify, catalog,
and quantify the known timescales and time lags in the M-I system
associated with reactions to the solar wind, with plasma transport,
with morphological evolution, with the evolution of plasma populations
and radiation belts, with ionospheric outflows, etc. The second
purpose is to identify and catalog the feedback loops in the driven M-
I system. Put on your thinking caps and join this discussion.

'''Session 2:''' "Long-Running Measurements of the State of the System: What
Can Be Done?" We rely chiefly on the geomagnetic indices to
characterize the reaction of the magnetosphere to solar-wind driving.
Are there other measures of the system that can and should be used?
Can we create long-running, continuous "indices" that characterize the
state of the electron radiation belt, the rate of ion outflow from the
ionosphere, the stretching of the magnetotail, the polar-cap size,
plasma-wave intensities, the global TEC, NOX densities, etc. We are
asking participants to suggest and defend ideas for important
measurements of the system and to say how feasible it would be to make
an index of that measurement. Discussion without slides is optimal.
Please contact the conveners about ideas.

A third GSS planning session will also be held, plus two joint
sessions to be announced separately.

== [[FG: Inner Magnetosphere Cross-Energy/Population Interactions|Inner Magnetosphere Cross-Energy/Population Interactions]] ==
''Conveners: Yiqun Yu <yiqun [at] lanl.gov>, Colby Lemon <colby [at] aero.org>, Michael Liemohn <liemohn [at] umich.edu>, and Jichun Zhang <jichun.zhang [at] unh.edu>''

We would like to call for research and participation in the new Focus
group "Inner magnetosphere cross-energy/population interactions", held
at the GEM summer workshop in Portsmouth, VA. There will be three
sessions:

'''Session 1''' (Thursday, June 19, 1:30-3:00pm): "Influence of
plasmasphere/ring current populations on wave excitation and particle
distribution, and feedback on these populations." The purpose of this
session is to build on what was learnt from the past Focus Group
"plasmasphere-magnetosphere interaction" and apply that to couple the
plasmasphere with higher-energy population, and therefore continue the
discussion on the coupling between the plasmasphere, waves, and ring
current.

'''Session 2''' (Thursday, June 19, 3:30-5:00pm): "Coupling of ring current plasma with fields." There has been significant modeling effort on improving the self-consistency between the plasma and fields (both electric and magnetic). We would like to move forward and continue to improve the modeling capability by stimulating the development of more comprehensive, full-physics models that could account for self-consistent cross-energy/population coupling processes.

'''Session 3''' (Friday, June 20, 10:30-12:15pm): "Improve the full self-consistent link between the wave-particle interactions, particle
precipitation, and ionospheric conductivity model." We call for
modeling efforts from different regions to couple the necessary
physical models, such as an ionospheric conductivity model based on
particle precipitation due to inner magnetosphere wave-particle
interactions, and the feedback effects on the ring current/radiation
belts. This session will also invoke planning discussion for our
future direction.

== [[FG: Quantitative Assessment of Radiation Belt Modeling|Quantitative Assessment of Radiation Belt Modeling]] ==
''Conveners: Jay Albert, Wen Li, Steve Morley, Weichao Tu''

At this year's GEM Summer Workshop we will start a new Focus Group on
"Quantitative Assessment of Radiation Belt Modeling". The goals of our
FG are to bring together the current state-of-art models for the
acceleration, transport, and loss processes in radiation belts,
develop event-specific and global wave, plasma, and magnetic field
models to drive these radiation belt models, and combine all these
components to achieve a quantitative assessment of radiation belt
modeling by validating against contemporary radiation belt
measurements.

Five sessions have been planned for the upcoming GEM workshop:

'''Session 1''' (Tue, 10:30-12:15 PM): "Joint Session with Radiation Belts &
Wave Modeling focus group". In this joint session, the RBWM FG
(finishing this year) will wrap up their accomplishments in the past 5
years and then set up the stage for our introduction of the new FG of
Quantitative Assessment of Radiation Belt Modeling. We will discuss
the remaining open questions in RB modeling and connect them to our FG
goals and challenges.

'''Session 2''' (Tue, 01:30-03:00 PM): "Review existing RB models and
discuss where we are and what are needed". In this session, we solicit
short presentations discussing the existing models for the
acceleration, transport, and loss of radiation belt particles. In
general, we welcome talks that not only showcase their results, but
also include discussions like: "Mechanism ____ is evidently necessary,
though not sufficient since ___." We will discuss questions such as:
what are "standard" RB codes not doing well enough? vs. What are we
not doing at all but probably should be?

'''Session 3''' (Tue, 03:30-05:00 PM): "Various magnetospheric wave
characteristics and their global distribution required in RB modeling".
In this session, we solicit short presentations focusing on
characterizing various wave properties that are required as inputs to
RB models. The topics will cover ULF waves, chorus and hiss, EMIC
waves, magnetosonic waves, etc., and their effects on RB particles. We
will review the available wave models and discuss what are still
missing for RB modeling.

'''Session 4''' (Wed, 10:30-12:15 PM): "Seed populations, plasma density, and magnetic field configuration required in RB modeling".
In this session, we solicit short presentations specifying other required inputs for driving RB simulations, which include particle seed populations, plasma density, magnetic field configuration, last closed drift shell, etc. Again, we will review what are currently available and discuss what are still missing.

'''Session 5''' (Wed, 01:30-03:00 PM): "Wrap-up discussion and plan for future FG activities". In this final session, we will wrap up this
year’s FG with more big-picture discussions, and plan for future FG
activities for mini-GEM and next year. One important future activity
is the 'RB dropout' and 'RB buildup' Challenges. Here we solicit short
presentations proposing interesting dropout/buildup events for our
future challenges.

If you would like to present in any of these sessions, please send
your talk title and the relevant session number to Weichao Tu
(wtu [at] lanl.gov) by June 6, 2014. We will review the talks and announce the detailed session agenda before the meeting. Participation in discussions and brief walk-in talks are always welcomed.

Thank you in advance for your contributions!
