Initial Request
----------------------------------------------------------------
Hi
My name is Elelwani, I'm using MET for the first time. I'm using WRF data(grib format) for precipitation as my forecast and TRMM data(netcdf format) for observations. I'm trying to test this data using grid-stat and mode tools. I'm experiencing an error ie NetCDF: Attribute not found. Can you please assist.
Thank you in advance.

Elewani,
Thanks for filling out the registration info. I see from your
original email that you're trying to compare WRF output in GRIB format
to TRMM data in NetCDF format. That error "NetCDF: Attribute not
found" means something's wrong with the NetCDF file you're passing to
Grid-Stat and MODE.
Could you please send me a sample WRF file (GRIB) and the TRMM NetCDF
file you're using? Also, please tell me what version of MET you're
using. You can send me data by posting it to our anonymous
ftp site, following these instructions:
http://www.dtcenter.org/met/users/support/met_help.php#ftp
Please write me back once you've put it there, and I'll grab it. I'll
run it here through the debugger to figure out exactly where the
problem is.
Thanks,
John Halley Gotway

Hi
This is Elelwani from South Africa, I want to run point stat tool, is
it possible to run the tool without PREPBUFR formatted files. If not
is it possible for me to get the data for my region.
Thank you in advance.

Elewani,
The point-stat tool is used to compared a gridded forecast file to
point observations. Those point observations must be in a NetCDF
format that MET expects. In METv4.1, there are 3 tools which put
observations into the expected format: pb2nc, madis2nc, and ascii2nc.
Those tools take as input PREPBUFR files from NCEP, MADIS NetCDF
files, and ASCII point observations, respectively.
If you have observations available that you'd like to use for
verification, I'd suggest using the ASCII2NC tool. You could probably
reformat them into the 11 column format that ascii2nc expects and
then prepare the data for point-stat.
If you do not have observations available, then I'd suggest starting
with the GDAS PREPBUFR observations from NCEP. GDAS stands for Global
Data Assimilation System and should include observations
over South Africa. For example, here's the steps I followed to check
that:
(1) Retrieve a recent PREPBUFR file:
wget
http://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gdas.20130826/gdas1.t12z.prepbufr.nr
(2) Run it through pb2nc to convert it:
METv4.1/bin/pb2nc gdas1.t12z.prepbufr.nr gdas1.t12z.prepbufr.nc
PB2NCConfig
(3) Run plot_point_obs to show the location of the data:
METv4.1/bin/plot_point_obs gdas1.t12z.prepbufr.nc
gdas1.t12z.prepbufr.ps -dotsize 0.25
(4) Convert the output PostScript image to a png:
convert -rotate 90 gdas1.t12z.prepbufr.ps gdas1.t12z.prepbufr.png
I've attached the resulting image. As you can see, the GDAS data does
contain some observations over South Africa. There is one dot in the
plot for each lat/lon location containing an observation.
But this is a mixture of all observation types available in the
PREPBUFR file.
Hope that helps.
Thanks,
John Halley Gotway

Hi, I’m trying to run point_stat tool using the data below but I get
the error "fcst" not defined in this scope!. I have loaded my files
via FTP to the directory called phaduli_data under

be the problem.

Elewani,
I pulled your data and see the problem. You've defined the "field"
parameter outside of the "fcst" dictionary setting. Instead, "field"
needs to be a member of the "fcst" dictionary. Take a look at
the attached version of the config file, and you'll see what I mean.
Next, I see that your forecast file contains 73 lead times, hourly
from lead time 0 to 72. When I reran with the updated config file,
Point-Stat was grouping together all of the lead times into a
single verification task, trying to do all 73 times at once. Instead,
I specified a single lead time using:
lead_time = "120000";
Then Point-Stat only tried to verify the 12-hour lead time. But I
still got 0 matched pairs. To figure out why, I reran Point-Stat with
the verbosity level set to 3 (-v 3), and here's what I see in
the output:
DEBUG 2: Processing TMP/Z2 versus TMP/Z2, for observation type ADPUPA,
over region FULL, for interpolation method UW_MEAN(1), using 0 pairs.
DEBUG 3: Number of matched pairs = 0
DEBUG 3: Observations processed = 290206
DEBUG 3: Rejected: GRIB code = 284729
DEBUG 3: Rejected: valid time = 5477
DEBUG 3: Rejected: bad obs value = 0
DEBUG 3: Rejected: off the grid = 0
DEBUG 3: Rejected: level mismatch = 0
DEBUG 3: Rejected: quality marker = 0
DEBUG 3: Rejected: message type = 0
DEBUG 3: Rejected: masking region = 0
DEBUG 3: Rejected: bad fcst value = 0
DEBUG 3: Rejected: duplicates = 0
We have 0 matches because of a mis-match in the forecast and
observation valid times. So let's look at those. Using wgrib to list
the forecast file, I see that it was initialized at 2013071518. So
the valid times are anywhere between that time and that time plus 72
hours. Using ncdump to list the NetCDF point observation file (ncdump
-v hdr_vld), I see that the valid times are between
20130826_103000 and 20130826_133000.
So it looks like your forecast and observation valid times are off by
about 1 1/2 months. So you should grab the observations that are
valid at the forecast time you'd like to evaluate and try again.
Hope that helps get you going.
Thanks,
John Halley Gotway

Elewani,
Regarding the other data from the Unified Model - is it in GRIB format
but it just uses a different table? The GRIB1 table information that
MET uses can be found it
METv4.1/data/table_files/nceptab_flat.txt. If your Unified Model data
is in GRIB format, you should be able to use it in MET. But if the
variable names don't match what you'd expect, you may need to
modify that table file to get it to do what you'd like.
Hope that helps.
Thanks,
John

> The point-stat tool is used to compared a gridded forecast file to
point observations. Those point observations must be in a NetCDF
format that MET expects. In METv4.1, there are 3 tools which put
observations into the expected format: pb2nc, madis2nc, and ascii2nc.
Those tools take as input PREPBUFR files from NCEP, MADIS NetCDF
files, and ASCII point observations, respectively.

reformat them into the 11 column format that ascii2nc expects and then
prepare the data for point-stat.

with the GDAS PREPBUFR observations from NCEP. GDAS stands for Global
Data Assimilation System and should include observations over South
Africa. For example, here's the steps I followed to check that:
