2010 Summer Workshop

(This page is being updated.)

GEM will be holding its annual summer workshop at the Snowmass Conference Center in Snowmass, Colorado during June 20-25, 2010. A special student program will be held on Sunday, June 20.

Logistical information and workshop agenda can be found at the GEM Workshop Web Site.

Listed below are the call for presentations by various GEM focus groups before the Workshop. (Note: In the e-mail addresses below the symbol @ is replaced by " [at] ".)

GGCM Metrics and Validation

Conveners: Aaron Ridley <ridley [at] umich.edu> and Masha Kuznetsova <Maria.M.Kuznetsova [at] nasa.gov>

A new Dst index metrics study is added to the GEM Modeling Challenge organized by the GGCM Metrics and Validation Focus Group. Community Coordinating Modeling Center (CCMC) is supporting the Challenge. To participate in the Challenge please submit your model results using the web interface prior to June 1st, 2010.

The results of the Challenge will be discussed at the GGCM Metrics and Validation Session at the GEM 2010 Summer Workshop. Joint publication by all participants is planned. For more details, go to the Challenge Web site: http://ccmc.gsfc.nasa.gov/support/GEM_metrics_08/

Please send questions, comments and suggestions to: Masha Kuznetsova (Maria.M.Kuznetsova[at]nasa.gov) and Aaron Ridley (ridley[at]umich.edu).

GGCM Modules and Methods

Conveners: Brian Sullivan (bsullivan [at]artemis.sr.unh.edu); John Dorelli (john.dorelli [at] nasa.gov)and Michael Shay (shay [at] udel.edu)

The GGCM Methods and Modules Focus Group will hold 2 sessions at the upcoming GEM Summer Workshop in Snowmass (June 20-25, 2010). The sessions will be at 10:30 and 1:30 on Wednesday.

The overarching goal of this focus group is to understand the physics of collisionless magnetic reconnection on magnetospheric length scales (100-1000 ion inertial lengths). We invite potential contributors to participate with short presentations on the following topics:

1. Scaling of reconnection with local and kinetic scale parameters in MHD, multifluid, and kinetic models.

2. Plasmoid instabilities in high Lundquist number current sheets

3. Dependence (or independence) of the dayside reconnection rate on solar wind parameters.

or any other topics of interest to the focus group. This is the final year of the GGCM Methods and Modules Focus Group. Looking forward, as this focus group comes to an end, a major goal for this year's sessions will be to agree on a way to present the most significant results of geophysical magnetic reconnection research to the greater GEM community and to identify a few outstanding questions to address as we plan for future focus groups centered on the multi-scale physics of reconnection in the magnetosphere. A more detailed description of the objectives of this focus group can be found at

Potential Contributors are encouraged to contact Brian Sullivan (brian.sullivan [at] unh.edu) with the title of their presentation.

Bow Shock Phenomena and their Magnetospheric Impacts

Conveners: N. Omidi <omidi [at] solanasci.com>, D. Sibeck <david.g.sibeck [at] nasa.gov>

Plasma Entry and Tranport into and within the Magnetotail (PET)

Conveners: Antonius Otto <ao [at] how.gi.alaska.edu>,Jay R. Johnson <jrj [at] pppl.gov>, and Simon Wing <Simon.Wing [at] jhuapl.edu>

We would like to invite contributions to the PET focus group at the upcoming GEM workshop in Snowmass on June 21-25, 2010. The sessions will be held in a workshop (NOT AGU) style in which each speaker will be allotted time for a 2-3 slides, in order to ensure enough time for discussion. In order to encourage this, at least one of the slides should deal with unresolved issues. Speakers are encouraged to end the presentation with outstanding questions rather than a summary of what has/have been accomplished. It is expected that there will be three sessions: (1) ion outflow effects on the plasma sheet; (2) Constraints on plasma sheet entry and transport; and (3) GEM challenge, northward and southward IMF.

All three sessions have been tentatively scheduled on Monday Jun 21 (See http://www.cpe.vt.edu/gem/index.html for the definitive schedule). If you have not already done so, please send the title(s) and session(s) of your contribution(s) to us at your earliest convenience at the email addresses given above.

Physical Processes in the Cusps: Plasma Transport and Energization

Conveners: K.J. Trattner, N. Omidi and D. Sibeck

Magnetosphere-Ionosphere Coupling, Electrodynamics and Transport (MICET) (No session)

(The MICET Focus Group officially ended in 2008.)

Near Earth Magnetosphere: Plasma, Fields and Coupling

Conveners: Focus Group co-chairs: Sorin Zaharia <szaharia [at] lanl.gov>, Stan Sazykin <sazykin [at] rice.edu> and Benoit Lavraud <Benoit.Lavraud [at] cesr.fr>

Space Radiation Climatology

Conveners: Paul O'Brien (paul.obrien [at] aero.org);Geoff Reeves (reeves [at] lanl.gov), Bob Weigel (rweigel-at-gmu.edu), and Reiner Friedel (friedel-at-lanl.gov)

It's almost time for the GEM Summer Workshop, joint with CEDAR. The Space Radiation Climatology Focus Group (FG9) will meet for three breakout sessions: two on Thursday June 24th: 1:30-3:30 and 3:30-5, and one on Friday, the 25th, 10:30-12:15. We will be discussing the past year's results in reanalysis, data assimilation, climatology models, and long-term data/analysis. One of our sessions (the first one) will be joint with the new radiation belt focus group.

We already have a number of exciting talks lined up, but there's plenty of room for more. We encourage interested parties to send talk ideas to Paul O'Brien, Bob Weigel, and/or Reiner Friedel (Geoff will not be able to attend this year). If you are presenting an FG9-related poster, please sign up for the **Thursday** Poster Session and advertise on the Wiki. http://www.virbo.org/GEM_FG9_2010
