GEOS-Chem is a global 3-D chemical transport model (CTM) for atmospheric composition driven by meteorological input from the Goddard Earth Observing System (GEOS) of the NASA Global Modeling and Assimilation Office. It is applied by research groups around the world to a wide range of atmospheric composition problems. Scientific direction of the model is provided by the international GEOS-Chem Steering Committee and by User Working Groups. The model is managed by the GEOS-Chem Support Team, based at Harvard University and Dalhousie University with support from the US NASA Earth Science Division and the Canadian National and Engineering Research Council.

GEOS-Chem is a grass-roots community model owned by its users, and ownership implies some responsibilities as listed in our welcome page for new users. If you are interested in using GEOS-Chem, please contact the GEOS-Chem Support Team who will send you instructions for joining the user community and accessing the code.
