[Met_help] [rt.rap.ucar.edu #82000] History for pcp_combine with ensemble stat output

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

Hi,

I'm trying to use the pcp_combine tool to add together 1-hr accumulations
from 3 different files to get a 3-hr accumulation.  The files I'm trying to
use were produced by the ensemble stat tool and they contain the ensemble
mean for 1-hr APCP.

Here is the command I am running:

pcp_combine -add ensemble_stat_20170909_010000V_ens.nc 1
ensemble_stat_20170909_020000V_ens.nc 1 ensemble_stat_20170909_030000V_ens.nc
1 ncar_3km_2017090900_mean_f003.nc

This is the error message I get:

DEBUG 1: Reading input file: ensemble_stat_20170909_010000V_ens.nc
ERROR  :
ERROR  : get_field() -> can't get data plane from file
"ensemble_stat_20170909_010000V_ens.nc"

I noticed this issue is similar to #75994 (About pcp_combine) but when I
tried Julie's suggestion of specifying the name and level in the
pcp_combine command I got the same error.

pcp_combine -add ensemble_stat_20170909_010000V_ens.nc 'name="APCP_01";
level="A01";' ensemble_stat_20170909_020000V_ens.nc 'name="APCP_01";
level="A01";' ensemble_stat_20170909_030000V_ens.nc 'name="APCP_01";
level="A01";' ncar_3km_2017090900_mean_f003.nc

Here is some information about the variable within the NetCDF file (from
ncdump):

float APCP_01_A01_ENS_MEAN(lat, lon) ;
                APCP_01_A01_ENS_MEAN:name = "APCP_01" ;
                APCP_01_A01_ENS_MEAN:long_name = "APCP_01 at A01 Ensemble
Mean" ;
                APCP_01_A01_ENS_MEAN:level = "A01" ;


Any help would be greatly appreciated!

Thanks,
Ben

Hi,

I was actually just able to figure out what I was doing incorrectly.
It
worked when I tried the following:

ensemble_stat_20170909_010000V_ens.nc 'name="APCP_01_A01_ENS_MEAN";
level="(*,*)";'

I was confused because ncdump specified the name as APCP_01 and the
level
as A01, but now I understand what was happening.

This ticket can be closed - thanks!

Ben
