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 2015 GEM Summer Workshop will be held in Snowmass, Colorado during June 14-19, 2015. Information about the Workshop can be found at the GEM Workshop website at Virginia Tech. A tentative list of oral presentations is available at GemWiki's 2015 Summer Workshop page.
• The following new Focus Groups have been selected to start in Summer 2015: (1) Testing Proposed Links between Mesoscale Auroral and Polar Cap Dynamics and Substorms; (2) Tail Environment and Dynamics at Lunar Distances.
• An annual GEM mini-workshop was held in San Francisco on December 14, 2014 before the Fall AGU Meeting. See here for the session schedule.
