3. 2016 Joint GEM-CEDAR: "Magnetic Reconnection in the Magnetosphere" Focus Group Sessions
From: Paul Cassak, Andrei Runov, Yi-Hsin Liu, Brian Walsh (Paul.Cassak at mail.wvu.edu)

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

We have a broad collection of sessions planned for this year, including both basic reconnection science and joint sessions with focus groups where reconnection plays a role in the broader dynamics.  The sessions are intended to be driven by open discussion, but attendees are encouraged to enhance the discussion by showing a slide or two as appropriate.  As in the past, we are asking participants to not do AGU-style presentations.  As always, we will try to accommodate all who want to speak, but the priority is having open and active discussion over sticking to a schedule.  We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.  

The (currently scheduled) dates, times, and summaries for each session are:

Monday 6/20, PM1 - 1:30pm-3:30pm (Individual session)

This session will focus on kinetic physics in day- and night-side reconnection.  With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics.  Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data.  In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL).  We also encourage discussion on other relevant topics.  Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you are interested in being part of the discussion.

Monday 6/20, PM2 - 4:00pm-6:00pm (Joint with Mesoscale Auroral and Polar Cap Dynamics and Substorms focus groups)

We will discuss the following topics: 

  -- Ionospheric signatures of magnetopause reconnection and FTEs 
  -- Possible dayside-nightside coupling (remote observations, modeling, tests for in-situ multi-point observations) 
  -- The role of the ionosphere in transient day- and night-side reconnection-related processes

Contributions from ground- and space-based observers as well as from modelers are welcome.  Please contact Brian Walsh <bwalsh at bu.edu> if you are interested in being part of the discussion.

Tuesday 6/21, PM1 - 1:30pm-3:30pm (Joint with Dayside Kinetic and Transient Phenomena focus groups)

This session will encourage cross-focus group interaction and open ended discussion on the topics of magnetopause reconnection, flux-transfer events, Kelvin-Helmholtz instability, magnetopause waves, and other boundary layer processes. Talks on MMS-related studies and modeling with the emphasis on global magnetospheric aspects of reconnection are especially encouraged.  Please contact Yi-Hsin Liu <yi-hsin.liu at nasa.gov> by Friday, June 10 if you are interested in being part of the discussion.

Friday 6/24, PM1 - 1:30pm-3:30pm (Individual session)

This session will be an open forum for discussion of topics about reconnection in the magnetosphere.  It may include discussion from any of the earlier sessions as interest dictates.  In addition, there will be an update on efforts to incorporate kinetic modeling into NASA’s CCMC.  We also hope there is time for a discussion on topics of interest for next year, and the potential future of the reconnection focus group beyond when the current version ends next year.  Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you would like to offer a discussion topic.

We look forward to seeing you at the sessions!  Please let one of the organizers know if you have any comments, questions or suggestions.

4. 2016 Joint GEM-CEDAR: Call for Participation in the "Inner Magnetosphere Cross-Energy/Population Interactions (IMCEPI)" Sessions
From: Colby Lemon, Mike Liemohn, Yiqun Yu, Jichun Zhang (yiqunyu17 at gmail.com)

Dear Colleagues, 

We invite you to participate in the GEM Focus Group “Inner Magnetosphere Cross-Energy/Population Interactions (IMCEPI)” at the 2016 CEDAR-GEM Workshop at Santa Fe, New Mexico. We would like to solicit short talks focused on the inner magnetosphere coupling physics, as well as the coupling to the ionosphere system. 

Session 1 (13:30-15:30, Monday, 06/20, O’Keefe+Milagro+Kearny): Joint with GEM Focus Group “storm-time inner magnetosphere ionosphere convection (STIMIC)” 

A thorough understanding of the inner magnetosphere dynamics requires an integrated investigation of the magnetosphere ionosphere system, as the ionosphere provides the inner magnetosphere with an energy reservoir through particle precipitation as well as feedbacks with convectional/pulsing electric field that changes the transport of energetic particles in plasmasphere/ring current. 

In this joint session, we would like to solicit studies on the impacts of large-scale or transient electric fields on inner magnetosphere populations, and on the role of particle precipitation of magnetospheric origin on the ionospheric electrodynamics. Topics include but not limit to the improvement of electric field self-consistency in global models, establishment of the connection between inner magnetosphere populations and convective or SAPS electric field, and the influence of precipitation on the ionospheric conductivity, etc.

Session 2 (13:30-15:30, Friday 06/24, Sweeney C): plasma wave dynamics and coupling with inner magnetosphere populations. 

In this session, we will focus on magnetospheric particle dynamics and their role in the generation of plasma waves, and the feedback effect of plasma wave dynamics on the dynamics of plasmasphere, ring current, and radiation belts,  

Session 3 (16:00-18:00, Friday 06/24, Sweeney C): coupling between fields and plasma, and discussion on challenge events. 

We will focus on the interactions between plasma and electric/magnetic fields in the mid-tail to inner magnetosphere/ionosphere region, and the role of mid-tail dynamics on the inner magnetosphere dynamics.

We will also discuss on challenge events. Topics of challenge include ionospheric conductance challenge, role of electric field, etc. We invite you to participate in the following challenge events and other interesting ones: a) January 25-26, 2013; b) March 17, 2013.

Please let us know if you are interested in presenting your research!

5. 2016 Joint GEM-CEDAR: “Quantitative Assessment of Radiation Belt Modeling” Focus Group -- Call for Presentations
From: Weichao Tu, Wen Li, Jay Albert, and Steve Morley (wetu at mail.wvu.edu)

We would like to solicit short presentations relevant to the following four sessions, including three independent sessions and one joint session with the “ULF Wave Modeling, Effects, and Applications” FG. 

Session 1 (Tue, 01:30-03:30 PM): “Radiation Belt (RB) particles and modeling”. We solicit short presentations discussing the observational and modeling results for the acceleration, transport, and loss of radiation belt particles. Possible topics also include the required inputs for driving RB simulations, such as seed particle populations, plasma density, magnetic field configuration, last closed drift shell, etc., and non-traditional mechanisms such as drift orbit bifurcations.

Session 2 (Wed, 01:30-03:30 PM): “Waves and local interactions”. We solicit short presentations focusing on characterizing various wave properties that are required as inputs to RB models. In this session we will focus on waves and structures that can have local interactions with RB particles, such as, chorus, hiss, EMIC waves, magnetosonic waves, nonlinear structures, etc., and their effects on RB particles.

Session 3 (Fri, 01:30-03:30 PM): “ULF waves and nonlocal transport”. This is the joint session with “ULF Wave Modeling, Effects, and Applications” FG.  Since the two FGs have common interest in understanding ULF wave driven radiation belt transport, we call for short presentations that focus on ULF waves and address the role of ULF waves in the acceleration, transport, and loss of RB particles. Possible topics include ULF wave characterization, radial diffusion coefficients, diffusive versus non-diffusive transport, etc.

Session 4 (Fri, 04:00-06:00 PM): “RB "dropout" and "buildup" challenges and future plans”. This session will focus on the four "challenge" events that have been selected by the community:
#1. Stormtime Enhancement: 2013-03-17/00 UT to 2013-03-19/00 UT 
#2. Stormtime Dropout: 2013-05-31/00 UT to 2013-06-03/00 UT
#3. Non-storm Enhancement: 2013-09-19/00 UT to 2013-09-21/00 UT
#4. Non-storm Dropout: 2013-09-23/00 UT to 2013-09-26/00 UT 
We encourage presentations on the RB modeling results of these events as well as studies specifying the required inputs for modeling the RB dynamics during these events (e.g., various magnetospheric waves, plasmapause and density models, electron PSD data). More information on these events and the available resources can be found at our GEM wiki page (http://www-ssc.igpp.ucla.edu/gemwiki/index.php/FG:_Quantitative_Assessment_of_Radiation_Belt_Modeling). At last, we will wrap up and plan for future FG activities.

If you would like to present in any of these sessions, please send your talk title and the relevant session number to Weichao Tu (wetu at mail.wvu.edu) by June 12th, 2016. Our FG activities and announcements will be updated in the GEM wiki page.

Thank you very much in advance for your contributions!
