This step-by-step guide provides instructions for running the standalone version of the GTMM to a pre-anthropogenic equilibrium. This document contains information from on the GTMM manual

1. Set Up GTMM Directories

Follow instructions in the GTMM/GEOS-Chem Odyssey Guide to set up directories and download data files. 

Directories include:

YOUR_SOURCE_DIRECTORY (i.e., GCgtmm)

YOUR_GTMM_DIRECTORY (i.e., GTMM)
