GEOS–Chem Wiki

The 9th International GEOS-Chem Meeting (IGC9) will be held at Harvard from May 6-9, 2019. Register today!

GEOS-Chem Community Mission: to advance understanding of human and natural influences on the environment
through a comprehensive, state-of-the-science, readily accessible global model of atmospheric composition.

The GEOS–Chem model is a global 3-D model of atmospheric composition driven by assimilated meteorological observations 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, Central management and support of the model is provided by the Atmospheric Chemistry Modeling Group at Harvard University.

This wiki is meant to facilitate communication between GEOS-Chem users and developers. If this is your first time here, check out the features page. If you would like to contribute to the wiki, please register as a user by clicking create account at the top right corner of this page.

New information is continually being added to the wiki, so please check back here often, or even better, subscribe to the recent changes' RSS feed: you will not miss a discussion!
