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.
