Description of your issue or question

I'm trying to set up a run in GEOS-Chem Classic ver. 14.1.1 with country level scale factors. Now, I have an error in HEMCO as like attached files. How can I solve it? HEMCO_Config.rc.txt GC.log

Hi @Meongdo-Jang, thanks for reaching out. The error is because HEMCO expects a different set of columns than the ones you programmed. I believe you need to put the country level scale factors entry in the scale factors section of HEMCO_Config.rc later in the file. Find this section of HEMCO_Config.rc and try moving your scale factors file entry there.

### END SECTION BASE EMISSIONS ###

Thanks! As like you mentioned, I got the following error.

----------------------------------------------------------
HEMCO ERROR: Cannot properly read mask coverage: COUNTRY_MASK

HEMCO ERROR: Error encountered in routine "UpdateDtaProperties"

This is an error when reading the configuration file. I searched the HEMCO code for string 'Cannot properly read mask cover' and found that the error is being tripped in here with this check:

      IF ( nEdges /= 4 ) THEN
          errMsg = 'Cannot properly read mask coverage: '                 // &
                   TRIM( Lct%Dct%cName )
          CALL HCO_Error( errMsg, RC, thisLoc )
          RETURN
       ENDIF

It looks like your country mask is not being parsed correctly because it is not in the correct location in HEMCO_Config.rc. It needs to be in the non-emissions data section. Look for this string in HEMCO_Config.rc:

###############################################################################
### NON-EMISSIONS DATA (subsection of BASE EMISSIONS SECTION)
###
### Non-emissions data. The following fields are read through HEMCO but do
### not contain emissions data. The extension number is set to wildcard
### character denoting that these fields will not be considered for emission
### calculation. A given entry is only read if the assigned species name is
### an HEMCO species.

Hi @Meongdo-Jang, were you able to get this to work?

Thank so much for your e-mail! Until now, I could't solve that.
