[Met_help] [rt.rap.ucar.edu #44719] History for pcp_combine

MET team,

Upon using the PCP_combine tool to combine several GRIB file precipitation
intervals into one netCDF output file, does one need to follow the netCDF
conventions for defining fcst/obs fields in the Point-Stat configuration
file?  Or should GRIB conventions be used (ie, APCP/A24, etc.)?

Thanks.

James,

Since the output of the PCP-Combine tool is NetCDF, you should use the
NetCDF convention in the MET configuration files.  An example of doing
this can be found in the test script for Grid-Stat
(METv3.0/scripts/test_grid_stat.sh).  For example, the first Grid-Stat
command in there makes use of the config file
METv3.0/scripts/config/GridStatConfig_APCP_12, and in that file,
you'll see:
   fcst_field[] = [ "APCP_12(*,*)" ];

The NetCDF variable name in this case is "APCP_12".  Since there are
only two dimensions for this variable for X and Y, you can omit the
"(*,*)" if you'd like.  If no dimensions are specified, MET
will assume "(*,*)".  So the following would work just as well:
   fcst_field[] = [ "APCP_12" ];

Hope that helps.
