Configure your simulation¶
We recommend that you configure your simulation before downloading data files. You can use the configuration settings with a dry-run simulation to download only the data that you will need.
You will need to edit various configuration files in order to specify options for your GEOS-Chem Classic simulation. These are described below.
Commonly-updated configuration files¶
When starting a new GEOS-Chem Classic simulation, you will usually edit most (if not all) of these configuration files:
All of the above-mentioned files are included in your GEOS-Chem Classic run directory.
Less-commonly updated configuration files¶
If you need to add or delete species, or to change the default photolysis and/or chemistry mechanism settings in your simulation, you’ll need to edit these configuration files:
