GEOS-Chem High Performance


This is a prerelease of the GEOS-Chem High Performance user guide. These pages are the most up-to-date and accurate instructions for GCHP, but they are still a work in progress.

Contributions (e.g., suggestions, edits, revisions) would be greatly appreciated. See editing this guide and our contributing guidelines. If you find a something hard to understand—let us know!

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.
