9. GEOS-Chem Components

The table below lists major components in GEOS-Chem, their source code module filenames, and links to relevant pages on the GEOS-Chem wiki.

IMPORTANT: Running GEOS-Chem with the recommended time steps for transport and chemistry from S. Philip et al (2016) has been shown to increase run times w/r/t GEOS-Chem v10-01 by approximately a factor of 2. To speed up GEOS-Chem simulations, users may choose to:
