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 2014 GEM Summer Workshop will be held during June 15-20, 2014 at the Renaissance Portsmouth Hotel & Conference Center in Portsmouth, Virginia. Please visit the Workshop Website for details.
  • The following proposals have been submitted for consideration of new GEM focus groups starting from Summer 2014:
  1. Analysis and Synthesis of Geospace Current Systems (Currents in Geospace)
  2. Geospace System Science
  3. Inner Magnetosphere Cross-Energy/Population Interactions (IMCEPI)
  4. Multi-scale Processes of Energetic Particles (PEP) in the Inner Magnetosphere
  5. Particle Populations in the Coupled Inner Magnetosphere
  6. Quantitative Assessment of Radiation Belt Modeling
  • The GEMstone Newsletter Volume 23 has been published and is available at Newsletters.
