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>).
+
 
+
For more information about the <tt>HEMCO_Config.rc</tt> file, please see:

+
== 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]], 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.  To see the HEMCO_Config.rc file that ships with the current version of GEOS-Chem, [https://github.com/geoschem/geos-chem/blob/dev/13.0.0/run/GCClassic/HEMCO_Config.rc.templates/HEMCO_Config.rc.fullchem please follow this link].

=== Default emissions settings ===

For example, the default emissions settings for the fullchem simulation are:

=== Disabling all emissions ===
+
 
+
All emissions can be turned off by changing
+
 
+
--> EMISSIONS              :      true
+
 
+
to
+
 
+
--> EMISSIONS              :      false.
+
 
+
=== Disabling meteorology inputs ===
+
 
+
Because HEMCO is used to read in the meteorology fields for GEOS-Chem "Classic", you should leave:
+
 
+
    --> METEOROLOGY            :      true
+
 
+
although for testing (e.g. in the HEMCO standalone) this can be toggled off by changing <tt>true</tt> to </false</tt>.
+
 
+
=== Disabling chemistry inputs ===
+
 
+
    --> CHEMISTRY_INPUT        :      true
+
 
+
=== Disabling other emissions
+
 
+
Base emissions can be toggled on/off by placing <tt>true</tt> or <tt>false</tt> after the semicolon that follows the inventory name. For example, this will turn off CEDS emissions:
+
 
+
      --> CEDS                  :      false    # 1970-2017
+
 
+
Emissions implemented as HEMCO extensions can be toggled on/off by placing <tt>on/tt> or <tt>off</tt> after the semicolon that follows the name of the extension. For example, this will turn off the HEMCO SeaFlux extension (which handles sea-to-air exchange of certain species):
+
 
+
  101    SeaFlux                : off  DMS/ACET/ALD2/MENO3/ETNO3/MOH
+
