Paul, removing the filters for latlon even though they were set wide open

fixed the problem - thanks.

I have another question:



I am combining WRF files to get the precipitation accumulation for

20110218_1200 initial time, 24 - 48 hour forecast amounts so I end up with the

amount of precip forecast to fall from 24-48 hours from the 20110218 12Z

initialized model run.  I am using PCPCombine.  The command line is:



/sphome/qcteam/METv3.0/bin/pcp_combine -sum 20110219_120000        3

20110220_120000 24

/h/data/global/WXQC/data/met/temp/pcpdir/wrf_pcp_data -pcpdir

/h/data/global/WXQC/data/met/temp/pcpdir -pcprx model_pcp



I get the message:



Performing sum command: Init/In_Accum/Valid/Out_Accum Times =

20110219_120000/030000/20110220_120000/240000



The model grib file that contains the precip amounts is model_pcp (attached).

It contains the following:

When I run this I get the message: ERROR: sum_grib_files() -> Cannot find a

file with a valid time of 20110220_120000 and accumulation time of 030000

matching the regular expression "model_pcp".  The 48hr WRF forecast should

have a valid time of 20110220 12Z.  So why am I getting this message?



Thanks



Bob
