GEOS-Chem Guides

We have created the following Guides to assist you in finding information on several important GEOS-Chem topics:

• Guide to compilers for GEOS-Chem
• Guide to GEOS-Chem History diagnostics
• Guide to GEOS-Chem simulations
• Guide to using Git with GEOS-Chem

The following Guides have been migrated to ReadTheDocs:

• Guide to HEMCO emissions diagnostics
• Planeflight diagnostic
• ObsPack diagnostic
• Prepare COARDS-compliant files
• Parallelize GEOS-Chem and HEMCO source code
• Speed up a slow simulation
• Understand what error messages mean
• Update chemical mechanisms with KPP'
• View GEOS-Chem species properties
• Work with netCDF files
