[BUG/ISSUE] Missing file errors not in HEMCO.log in GCHP

[lizziel]

GCHP user @clearsky112 reported in geoschem/GCHP#127 the following error in the primary GCHP log file when running. No HEMCO.log file was generated making it difficult to determine the problem.

 Error in HcoDiagn_Init called from HCO_Init

additional error messages!

The user figured out they could output the HEMCO.log file by changing the HEMCO_Config.rc setting for DiagnFreq from Monthly to End. This was presumably an issue because the test run was 1-hour, less than the 1-month frequency set for that field. After making this change, the HEMCO.log file was output successfully and contained error messages indicating the underlying problem, specifically that input files that were missing.

This is unexpected behavior for GCHP since we previously thought the DiagnFreq field was ignored. Diagnostic frequency is set in HISTORY.rc instead. However, it seems this field has an impact on creation of the HEMCO.log file. We should further investigate this so that it is a not a problem in future versions.

I am seeing this issue when testing GEOS-Chem 13.2 in GEOSgcm as well. I am currently looking into the issue and a fix.
