Geospace Environment Modeling (GEM) 
Geospace Environment Modeling (GEM) is a broad-based, community-initiated research program on the physics of the Earth's magnetosphere and the coupling of the magnetosphere to the atmosphere and to the solar wind. The purpose of the GEM program is to support basic research into the dynamical and structural properties of geospace, leading to the construction of a global Geospace General Circulation Model (GGCM) with predictive capability. This GGCM model will be modularized and will complement parallel developments of magnetohydrodynamic models. The strategy for achieving GEM goals is to undertake a series of campaigns and focus groups, in both theory and observational modes, each focusing on particular aspects of the geospace environment.
The Geospace Environment Modeling (GEM) program is sponsored by National Science Foundation (NSF) Division of Atmospheric and Geospace Sciences.
What's New
- The 2011 GEM Mini-workshop will be held on Sunday, December 4 at the
Westin San Francisco Market Street Hotel located at 50 Third Street. (Detailed schedule)

- The GEM Workshop website has made available the agenda for the 2011 Joint GEM/CEDAR Workshop in Santa Fe. See 2011 CEDAR-GEM Joint Workshop for the session announcements posted in GEM Messenger.
- The three new Focus Groups selected to start in Summer 2011 are: (1) Metrics and Validation, (2) The Ionospheric Source of Magnetospheric Plasma: Measuring, Modeling, and Merging into the GEM GGCM, and (3) Scientific Magnetic Mapping and Techniques. Details of Focus Group proposals can be found in the GEM Focus Groups section.
