The Geospace Environment Modeling (GEM) program is a National Science Foundation (NSF) Division of Atmospheric Sciences initiative to coordinate and focus research on the near-earth portion of geospace from the lower ionosphere to where the earth system interacts with 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 (GGCM) model with predictive capability. The GGCM effort is now being treated as a separate campaign. The strategy for achieving GEM goals is to undertake a series of campaigns, in both theory and observational modes, each focusing on particular aspects of the geospace environment.

Virtual GEM 2021 Information

The 2021 GEM Summer workshop will be a Virtual meeting, in a similar format as 2020 VGEM but extending over the full week of July 25-30, 2021.

Due to continuing uncertainties with the COVID-19 pandemic, the GEM Steering Committee decided to hold a fully virtual meeting in 2021. The Workshop Organizers continue negotiations with the hotel in Hawaii regarding the possibility to postpone the in-person summer workshop until 2022. The Steering Committee will provide feedback to the community once an agreement with the hotel is reached and plans are finalized. We appreciate your patience and understanding.

We are proceeding with the organization of the GEM Summer 2021 Workshop as a fully virtual meeting during the week of July 25-30, 2021. A decision was made to have a small registration fee to help cover the costs of the meeting and to support family grants. A subcommittee was formed to organize the plenary sessions. We envision a program that celebrates GEM 30th anniversary; please send us ideas on how to make this a memorable event, although we realize the big celebration will be once we meet in person!

Online. Information will be available at the GEM workshop website as time approaches.

Support for this workshop is made possible by the National Science Foundation.
