Sorry some correction below to the subtraction in PCP combine...
This,
The subtract command I used is as follows:
../METv3.0.1/bin/pcp_combine -subtract \
WRFPRS_d02_run0.028 28 WRFPRS_d02_run0.027 27 \
temp.grib \
should have been this instead:
The subtract command I used is as follows:
../METv3.0.1/bin/pcp_combine -subtract \
WRFPRS_d02_run0_regridded.028 28
WRFPRS_d02_run0_regridded.027 27 \
WRFPRS_d02_run0_subtracted.028 \
to match the actual files names that I've used.
Thanks,
Raizan

Raizan,
The output file from pcp_combine is a NetCDF file that should contain
a single variable APCP_01, in your case. You can
inspect the contents of this file, WRFPRS_d02_run0_subtracted.028,
using the ncdump command. If you use this utility,
you should see information about the APCP_01 variable. The syntax for
accessing this variable in the mode config file
is 'APCP_01(*,*)'.
The reason that the pcp_combine NetCDF output file is much smaller
than the input GRIB files may be that the output file
contains only a single gridded variable (precip), while your GRIB
files could contain many.
Also, as a matter of convention, we usually denote NetCDF files with
the suffix .nc to avoid confusion. So, in your
case, you may want to consider renaming your pcp_combine output file
to WRFPRS_d02_run0_subtracted.028.nc.
Please let me know if you have any other questions.
Thanks,
Paul
