Overview
You can archive any type of emissions (or other quantity) computed by the HEMCO emissions component to netCDF-format diagnostic output. The HEMCO_Diagn.rc file controls diagnostic output options for HEMCO.
You can see the HEMCO_Diagn.rc file that ships with GEOS-Chem 13.0.0 by following this link.
Sample HEMCO_Diagn.rc file
Here is a snapshot of the HEMCO_Config.rc for the GEOS-Chem fullchem simulation run directory.

As you can see, you can archive not only the total emissions for a given species, but also the individual emission sectors. This gives you much more flexibility over the GEOS-Chem bpch diagnostic output.
Once you have your HEMCO_Diagn.rc file customized for your given simulation, make sure that you have these settings in your HEMCO_Config.rc file:
DiagnFile: HEMCO_Diagn.rc DiagnPrefix: HEMCO_diagnostics DiagnFreq: End
where:
- DiagnFile specifies the location of the HEMCO_Diagn.rc file.
- DiagnPrefix specifies the the prefix for all HEMCO-generated diagnostic files.
- DiagnFreq specifies the diagnostic archival frequency.
You should not really have to edit HEMCO_Diagn.rc unless you are planning to add new species or emissions inventories. The default HEMCO_Config.rc file that ships with your run directory is set up to archive diagnostics for all defined emission species.
