Initial Request
----------------------------------------------------------------
I am having a problem using the point-stat tool with some different variables in the Prepbufr format. For example the variable "vs" (forecast) for 10m meridional wind I believe should compare with VGRD level Z10 in both the Prepbufr point observations and the climatology. Yet when I run the tool it doesn't process any matches, although it does find a forecast and climatology level. I can run the grid-stat tool using the same forecast and climatology fields, but a gridded analysis instead of point observations, and it works fine. I get the same problem with 200 mb level winds (P200), although I'm almost positive I have been able to get statistics such as RMSE with these variables in the point-stat tool a while ago. When I run the tool I get this:
DEBUG 3: Number of matched pairs = 0
DEBUG 3: Observations processed = 45684
DEBUG 3: Rejected: GRIB code = 45684
I must have the wrong variable name. I thought for zonal winds at 200 mb would have the variable name "UGRD" and the level is "P200" from this website http://www.nco.ncep.noaa.gov/pmb/docs/on388/table2.html. Do you know if this is incorrect or where I could get more info?

Here is the configuration file. I am also uploading some obs and fcst
data
to the ftp site in the "REES" directory.
Thank you,

Shannon,
Looking in your config file, I see the following:
grib_fields = [
{
name = "${obs_var}";
level = "${obs_lev}";
cat_thresh = [ ];
}
];
obs = {
message_type = [ "${mess_type}" ];
sid_exc = [];
field = grib_fields;
}
Do you have a script to wrap these calls to Point-Stat? I'm wondering
how
${obs_var} is getting set.

Subject: Trouble with Point-stat tool for some variables
From: John Halley Gotway
Time: Fri Mar 11 14:31:32 2016
Shannon,
I ran with your data and was able to reproduce the behavior you're
seeing:
DEBUG 3: Observations processed = 46351
DEBUG 3: Rejected: SID exclusion = 0
DEBUG 3: Rejected: GRIB code = 46351
Next, I ran plot_point_obs to see if your data has any wind obs in it:
plot_point_obs prepbufr.gdas.2015080100.nc prepbufr.gdas.2015080100.ps
-gc
34
...
DEBUG 2: Finished plotting 0 locations.
DEBUG 2: Skipped 0 locations off the grid.
And it does not... thus no matches. Since you're using GDAS point
observations, I likely has something to do with the quality marker
you're
using. Please look at the NOTE on the bottom of this page about GDAS
quality markers for surface observations:
http://www.dtcenter.org/met/users/downloads/observation_data.php
Thanks,
John

Hi John,
I think I downloaded all of the GDAS data with quality marker = 9
which
should preserve the surface variables. I am downloading some more
GDAS
data with quality marker = 15 to test it and I'll let you know how
that
goes.
Thanks,
