The GCHP documentation has moved to https://gchp.readthedocs.io/. The GCHP documentation on http://wiki.seas.harvard.edu/ will stay online for several months, but it is outdated and no longer active!

Overview
GEOS-Chem High Performance (GCHP) represents the next generation of GEOS-Chem. Capabilities that distinguish GCHP from standard GEOS-Chem (GEOS-Chem "Classic") include:
- Flexible-resolution simulations, from ~4° x 5° (C24) to ~0.25° x 0.3125° (C360) without the need for code edits or recompilation
- Use of the cubed-sphere (CS) grid, which eliminates the need for polar filtering and brings GEOS-Chem into line with the NASA GEOS AGCM
- MPI distributed-memory parallelization which enables running a single job across multiple machines
This page will guide you through the wiki pages to get started with the latest release of GCHP. For a very quick start guide, see also https://github.com/geoschem/gchpctm.
