This content has been migrated to the [https://geos-chem.readthedocs.io/en/latest/gcc-guide/03-config/hemco-config.html '''HEMCO_Config.rc''' chapter of <tt>geos-chem.readthedocs.io</tt>].

In [[GEOS-Chem v10-01]] and later versions, emissions are read, regridded, and calculated by the [[HEMCO|HEMCO emissions component]]. The emission settings are specified in the HEMCO Configuration file (<tt>HEMCO_Config.rc</tt>).

== Enabling and disabling emissions ==

The <tt>HEMCO_Config.rc</tt> file for each GEOS-Chem simulation contains a set of switches that allow you to quickly toggle individual emissions inventories on or off. 
+
−
 
+
−
Each time you [[Creating GEOS-Chem run directories|create a GEOS-Chem run directory from the Unit Tester]], a new <tt>HEMCO_Config.rc</tt> file with default emissions settings will be created in the run directory.  These default settings are located near the top of the <tt>HEMCO_Config.rc</tt> file.

For example, the default emissions settings for the "Standard" full-chemistry simulation are:
