Initial Request
----------------------------------------------------------------
Hello MET Helpdesk
I am trying to use point_stat to verify WRF against rain gauge data.
I am using METv4.0.
When I run
point_stat ./WRFPRS_d01.023 ./ascii2nc_lieb_2000.nc ./PointStatConfig_default
I get an error message:
DEBUG 1: Default Config File: /media/prod/chris/WRFv3.4.1/METv4.0/data/config/PointStatConfig_default
DEBUG 1: User Config File: ./PointStatConfig_default
ERROR :
ERROR : VarInfoGrib::set_dict() - unrecognized GRIB1 field abbreviation 'APCP_surface' for table version 2
ERROR :
I have post processed WRF with UPPv1.1
Which created a grib file called WRFPRS_d01.023.
The total precipitation variable in the grib file is called "APCP_surface".
If I try with fcst variable APCP, I get an error message:
ERROR : process_fcst_climo_files() -> no fields matching APCP/A24 found in file: ./WRFPRS_d01.023
If I try A1 instead of A24 I get.
ERROR : process_fcst_climo_files() -> no fields matching APCP/A1 found in file: ./WRFPRS_d01.023
I would lke to use MET to verify rainfall but it seams impossible.
Have I done something wrong with running UPPv1.1?
>From my wrf_cntrl.parm
" (ACM TOTAL PRECIP ) SCAL=( 5.0)
L=(10000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000)"
Any help would be appreciated.
Thanks

My config files looks like this:
// Forecast and observation fields to be verified
//
fcst = {
wind_thresh = [ NA ];
message_type = [ "ADPSFC" ];
field = [
{
name = "APCP_surface";
level = "A24";
cat_thresh = [ >0, >1, >5, >10, >25, >25 ];
}
];
};
obs = {
wind_thresh = [ NA ];
message_type = [ "ADPSFC" ];
field = [
{
name = "APCP";
level = [ "A24" ];
cat_thresh = [ >0, >1, >5, >10, >25, >25 ];
}
];
};

Michael,
Can you please try the following first... just edit your config file
like this:
//
// Forecast and observation fields to be verified
//
fcst = {
wind_thresh = [ NA ];
message_type = [ "ADPSFC" ];
field = [
{
name = "APCP";
level = "A24";
cat_thresh = [ >0, >1, >5, >10, >25, >25 ];
}
];
};
obs = fcst;
Then try running Point-Stat. If that doesn't fix the problem, can you
please send us the data you're passing to Point-Stat? You can follow
the instructions listed here to post data to our anonymous
ftp site:
http://www.dtcenter.org/met/users/support/met_help.php#ftp
Please send us:
(1) GRIB forecast file: WRFPRS_d01.023
(2) NetCDF point observation file: ascii2nc_lieb_2000.nc
(3) Point-Stat configuration file: PointStatConfig_default
I'll try running your data here and figure out what's going on.
Thanks,
John

Hi John,
Thanks for your reply.
After editing the config file so that obs=fcst I receive the following
error message:
ERROR : process_fcst_climo_files() -> no fields matching APCP/A24
found in file: WRFPRS_d01.023
I have uploaded my data to /incoming/irap/met_help/weston_data/
I think the units in my ascii file are incorrect for now. But I am
just trying to get the point_stat to run at this stage.

Hi Michael.
Thank you for providing your data.
Using "wgrib" (wgrib WRFPRS_d01.023 | grep APCP) to view the fields in
forecast file, I see that the file contains the 23 hour forecast:
278:9741704:d=00092800:APCP:kpds5=61:kpds6=1:kpds7=0:TR=4:P1=0:P2=23:TimeU=1:sfc:0-
23hr
acc:NAve=0
Given that information, you would want change the name from
"APCP_surface" to "APCP" in the fcst section of the config file and
provide the 24 hour forecast file instead or update the name and the
level if you wish to compare with the 23 hour forecast
name = "APCP_surface";
level = "A24";
to
name = "APCP";
level = "A23";
Using "ncdump" (ncdump -v obs_arr ascii2nc_lieb_2000.nc | more) to
view
the obs_arr data, I see that the file contains a 1 hour (3600s)
accumulation interval:
0, 61, 3600, -9999, 0,
The level in your config file in the obs section was
level = [ "A24" ];
but needs to be
level = [ "A1" ];
While you could compare the 24 hour forecast with the one hour
observations, it probably doesn't make much sense to do that. I would
suggest verifying against the one hour forecast file or summing up
your
point observations into 24 hour accumulations.
I hope this helps.
