Happy Friday!

I was just trying to run pcp-combine on MRMS precipitation data from 2020 using this command:

pcp_combine -sum 00000000_000000 1 20200811_000000 24 -pcpdir obs -field 'name="GaugeCorrQPE01H"; level="L0";' -name "APCP_24" mrms_24h.nc

However, I got an error message:

ERROR  : 
ERROR  : VarInfoGrib2::set_dict() -> unrecognized GRIB2 field abbreviation 'GaugeCorrQPE01H'
ERROR  : 

After chatting with @JohnHalleyGotway - we discovered that the MRMS MET GRIB tables have been updated to match the updated MRMS data (see MET issue for more details as well as the change log for the grib2_mrms.txt file).

Would it be possible to take the union of the old grib table entries and new grib table entries in order to make the grib2_mrms.txt file backward compatible for older MRMS data?

Thanks!
