Geospace Environment Modeling (GEM)

The Geospace Environment Modeling (GEM) program is a NSF‑funded research initiative that seeks to improve scientific understanding and predictive capability of Earth’s magnetosphere, its coupling to the atmosphere, and interaction with the solar wind. The program supports interdisciplinary projects that combine observations, theory, and advanced modeling to produce realistic, physics‑based simulations of the geospace environment. Funding is allocated through competitive grants, with up to 15 awards expected, each ranging from $150,000 to $200,000. The opportunity was posted on August 25, 2026 and closed on August 26, 2026; proposals are no longer being accepted. • Focus: Development of physics‑based models of the magnetosphere, ionosphere, and solar‑wind coupling • Funding: Estimated total $3 million; individual awards $150k–$200k • Number of awards: Up to 15 projects • Eligibility: Open to unrestricted entities (universities, research institutes, etc.) • Submission window: 08/25/2026 – 08/26/2026 (now archived) • Primary contact: Chia‑Lin Huang ([email protected], (703) 292‑7544)
