[Met_help] [rt.rap.ucar.edu #76182] History for pcp_combine question

Mon May 2 14:56:41 MDT 2016

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

Hi,
I have a question about pcp_combine. I am trying to run a operational HRRR
file through pcp_combine to create a netcdf file for 1 hourly accumulated
precip. There are two APCP fields in the file HRRR grib file. Record 733 is
a run-time accumulation and record 735 (the one I want) is an hourly
accumulation. I figured pcp_combine was going to complain because there are
two fields of the same name and I figured it would use the first.

Here is my output:
tuvok:/d1/TAIWIN_VX/scripts% /usr/local/met-5.1/bin/pcp_combine -add
/d1/TAIWIN_VX/data/opHRRR/regrid/grb2/2016010112/20160101_i12_f015_HRRR-NCEP_wrfnat.grb2

I am wondering if there is a way to explicitly tell it to use record 735?
If not, I will use the first record and just do the subtraction.

Thanks for your help!
Jamie

Hi Jamie.

I believe that running pcp_combine in the following way will select
record
735 and give you the output you would like:

pcp_combine -add 20160101_i12_f015_HRRR-NCEP_wrfnat.grb2 'name="APCP";
level="R735";' -name "APCP_01" HRRR-NCEP_wrfnat.20160101_i12_f015.nc

DEBUG 1: Reading input file: 20160101_i12_f015_HRRR-NCEP_wrfnat.grb2
DEBUG 1: Writing output file: HRRR-NCEP_wrfnat.20160101_i12_f015.nc

Instead of having the level as "L0", I told it to use "R735" to select
grib
record 735.  I put the output at /scratch/jpresto/for_jamie/
HRRR-NCEP_wrfnat.20160101_i12_f015.nc.

Please try this out and/or take a look at the output file and let me
know
if that looks like what you need.

Thanks,
Julie

Thanks so much. This worked great. I had looked through the User Guide
but
didn't notice a usage statement explaining this - might be worth
mentioning
somewhere. (Or maybe I missed it?!)
