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

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:

1:0:d=11021812:APCP:kpds5=61:kpds6=1:kpds7=0:TR=4:P1=21:P2=24:TimeU=1:sfc:21-24hr

acc:NAve=0

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

Bob,

Regarding mode_analysis, take a look at your mode output file.  The
latlong values for paired objects are all NA.  That
is why those filters don't work as you would expect.  Those filters
only apply to single mode objects.

Regarding pcp_combine, I looked in the GRIB file you sent me and I see
that it has an init time of 20110218_12:

$ wgrib -V model_pcp

Undefined parameter table (center 57-1 table 132), using NCEP-opn
rec 1:0:date 2011021812 APCP kpds5=61 kpds6=1 kpds7=0 levels=(0,0)
grid=255 sfc 21-24hr acc:
...


So, I just changed the init time on your pcp_combine call from
20110219_12 to 20110218_12, and I think it's doing what
you want it to now:

$ pcp_combine -sum 20110218_12 3 20110220_12 24 wrf_pcp_data -v 3
-pcpdir . -pcprx model_pcp
