Overview

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

For more information about the HEMCO_Config.rc file, please see:

Enabling and disabling emissions

The HEMCO_Config.rc 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 create a GEOS-Chem run directory from the Unit Tester, a new HEMCO_Config.rc file with default emissions settings will be created in the run directory. These default settings are located near the top of the HEMCO_Config.rc file.

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

# ExtNr ExtName           on/off  Species

If you would like to turn off NEI2011, simply change the true in this line:

     --> NEI2011           :       true

to false:

     --> NEI2011           :       false

And if you also wanted to turn off the MEGAN biogenic emissions, simply change the on in this line:

108     MEGAN             : on    ISOP/ACET/PRPE/C2H4/ALD2

to off:

108     MEGAN             : off    ISOP/ACET/PRPE/C2H4/ALD2

etc.
