| + | 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>]. |
| − | | + | |
| − | The [[HEMCO|Harmonized Emissions Component (HEMCO)]] reads emissions, meteorology inputs, and various types of non-emissions data into GEOS-Chem. You can choose which of these types of data to include in your simulation by editing the HEMCO Configuration file (<tt>HEMCO_Config.rc</tt>) in your GEOS-Chem run directory.
| + | |
| − | | + | |
| − | 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].

| − | === Enabling/disabling all emissions ===
| + | |
| − | | + | |
| − | All emissions can be turned off by changing
| + | |
| − | | + | |
| − | --> EMISSIONS : true
| + | |
| − | | + | |
| − | to
| + | |
| − | | + | |
| − | --> EMISSIONS : false
| + | |
| − | | + | |
| − | which can be convienient if you are debugging a problem.
| + | |
| − | | + | |
| − | === Enabling/disabling other inputs ===
| + | |
| − | | + | |
| − | Because HEMCO is used to read in the meteorology fields as well as non-emissions chemistry input data (such as prod/loss rates, etc.), you should leave:
| + | |
| − | | + | |
| − | --> METEOROLOGY : true
| + | |
| − | --> CHEMISTRY_INPUT : true
| + | |
| − | | + | |
| − | For testing or debugging purposes you can toggle these off by changing <tt>true</tt> to </false</tt>.
| + | |
| − | | + | |
| − | === Enabling/disabling individual emissions inventories ===
| + | |
| − | | + | |
| − | 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 extension's name. 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
| + | |
| − | | + | |
| − | etc.
