HEMCO_Config.rc, HEMCO_Diagn.rc

HEMCO_Config.rc

Like input.geos, information about the HEMCO_Config.rc file is the same as for GEOS-Chem Classic with a few exceptions. Refer to the HEMCO documentation for an overview of the file.

Some content of the HEMCO_Config.rc file is ignored by GCHP. This is because MAPL ExtData handles file input rather than HEMCO in GCHP.

Items at the top of the file that are ignored include:

  • ROOT data directory path

  • METDIR path

  • DiagnPrefix

  • DiagnFreq

  • Wildcard

In the BASE EMISSIONS section and beyond, columns that are ignored include:

  • sourceFile

  • sourceVar

  • sourceTime

  • C/R/E

  • SrcDim

  • SrcUnit

All of the above information is specified in file ExtData.rc instead with the exception of diagnostic prefix and frequency. Diagnostic filename and frequency information is specified in HISTORY.rc.

HEMCO_Diagn.rc

Like in GEOS-Chem Classic, the HEMCO_Diagn.rc file is used to map between HEMCO containers and output file diagnostic names. However, while all uncommented diagnostics listed in HEMCO_Diagn.rc are output as HEMCO diagnostics in GEOS-Chem Classic, only the subset also listed in HISTORY.rc are output in GCHP. See the HEMCO documentation for an overview of the file.
