Initial Request
----------------------------------------------------------------
Hello,
I have a question about setting up wind_thresh in config file: because the
wind can be negative and positive, so how to set them correctly?
e.g, which is correct:
wind_thresh = [ >=1&&<=5 || >=-5&&<=-1 , >=5.0&&<=10 ||>=-10&&<=-5,
>=10.0||<=-10 ];
or
|wind_thresh| = [ >=1&&<=5, >=5.0&&<=10, >=20 ];
Thank you.

Hi Binyu,
The wind_thresh is a filtering threshold which is applied to the wind
SPEED. While the individual U and V components can be positive or
negative,
the wind speed is always >= 0.
The wind_thresh applies to the processing of the VL1L2, VAL1L2, and
VCNT
line types which process U/V pairs. Let's say you've set:
wind_thresh = [ NA, ge1, ge5, ge10 ];
Instead of seeing only 1 VL1L2 output line, you'll get 4... one for
each
wind_thresh chosen.
The first one (wind_thresh = NA) will include all U/V pairs in the
masking
area.
The second one (wind_thresh ge1) will only include those U/V pairs
whose
corresponding wind speed is at least 1 m/s.
The third and fourth ones (wind_thresh ge5 and ge10) will only include
those U/V pairs whose corresponding wind speed is at least 5 m/s or
10m/s,
respectively.
The idea here is checking to see how the model performs light and
variable
winds (i.e. low wind speed) versus well-defined winds (i.e. high wind
speed).
Thanks,
John

John,
That makes sense for wind SPEED. Please look at the point_stat config:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_gec/parm/
PointStatConfig
field = [
{
name = "UGRD";
level = [ "P250" ];
cat_thresh = [ >=1.0, >=5.0 ];
},
the cat_thresh ONLY has positive too, does that mean both directions
will
be considered? (>= refers either ge 5 or le -5)?
One more question here: following your suggestion, I did create VL1L2
and
VCNT,but I got strange error (
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/METviewer_AWS/g2g)
when I
tried to load to METviewer ( I mentioned that in one of my previous
email,
but didn't get reply). Is there any plot in METviwer that can compare
the
wind direction b/t obs. and forecast?
Thank you.

Binyu,
You're right, the cat_thresh for UGRD of >=1.0 would only threshold
the
positive values. If you want to apply both positive and negative you
could
use:
cat_thresh = [ <=-1.0||>=1.0, <=-5.0||>=5.0 ];
Table 7.19 in the MET User's Guide describes the contents of the VCNT
line
type:
[image: Screen Shot 2020-07-31 at 4.06.47 PM.png]
Looking at the description of those statistics, it looks like you may
be
interested in FDIR, ORDIR, VDIFF_DIR, DIR_ERR, and DIR_ABSERR. And
METviewer should be able to plot those statistics from the VCNT line
type.
That being said, I have never actually done this myself for a model
evaluation.
If METviewer isn't loading VCNT lines or plotting the statistics from
them,
we'll need to let Tatiana Burek know so that she can fix it.
Thanks,
John

John,
Should I send another ticket to "Tatiana" about my log error to upload
point_stat*stat files to METViwer?
I just tried the new config file (cat_thresh = [ <=-1.0||>=1.0,
<=-5.0||>=5.0 ];) and the output are the SAME as using the old config
file (
cat_thresh = [ >=1.0, >=5.0 ];). Is this b/c I have too few matching
pairs
(only one or two pairs)?

Binyu,
I'm guessing that the output is not actually the same. In the VL1L2
and
VCNT lines, the FCST_THRESH and OBS_THRESH columns should now indicate
that
you're using different thresholds: '>=1.0' should now be changed to
'<=-1.0||>=1.0'
You should confirm that those have changed to be confident that you
actually ran the modified configuration. Once you've confirmed that,
if the
counts and stats are still the same, that's really just a function of
your
data... about which I have no idea.

To keep these issues straight, I just created a separate RT ticket for
Tatiana to look at. Hopefully you received a copy of it.
Thanks,

All the "FCST_THRESH and OBS_THRESH columns" are "NA". Does that
indicate
something wrong with my setting?
Here is my config file and one output:

From: binyu.wang at noaa.gov

Hello again,
Following your suggestion, I tried to look for more sites for
verification
by using prepbufr data. Unfortunately I always got "0 matching pair"
when I
applied PB2NC and ensemble_stat. Here is the directory:
cd
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ecf
% ./test_bufr.ecf >& bufr.log3
I tried to diagnose the problem by converting the prepbufr data to
grid
data using point_to_grid, the script is:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/Scripts/MET/pt2grid.sh
One of the output is:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ush/COMOUT/
regrid.prebufr.nc.txt
It seems the PRES field does not look correct to me: it is over
~20000mb,
which is impossible. I confirmed with prepbufr people, the unit inside
of
the prepbufr is mb, and the magnitude should be <1000mb. But I can not
find
where the error is. Any suggestions?
Thank you.

Binyu,
I believe that WCOSS is down this week and unavailable... at least on
the
development side.
If you're able to grab that sample data and post it on the RAL
anonymous
ftp site, I could grab it from there for testing.
If that possible, please follow the instructions posted here:
http://dtcenter.org/community-code/model-evaluation-tools-met/met-
help-desk#ftp
Thanks,
John Halley Gotway

Hello John,
There are some other files that may be involved to solve the problem,
so it
is better for me to just wait for WCOSS to come back...
Thank you,

Subject: wind_thresh
From: binyu.wang at noaa.gov
Time: Mon Aug 17 16:50:05 2020
I just uploaded some files for this question under the same directory
"wang". I do the point2grid with the prepbufr data because I got " 0
pairing" using "ensemble_stat".
I converted the prepbufr data to grid data using point_to_grid,
the script is "pt2grid.sh"
the model file: gec00.t00z.pgrb2p5.0p50.f000
the prepbufr file:prepbufr.gdas.2020020100
config file: PB2NCConfig_gens
one output I got: regrid.prebufr.nc.txt
The PRES field does not look correct to me: it is over ~20000mb, which
is
impossible. I can not figure it out why?

Hello John,
Just want to remind that I am still waiting for the answer. I am sorry
to
keep asking questions: I guess I am the one with most of the
questions.

Subject: wind_thresh
From: John Halley Gotway
Time: Thu Aug 27 15:00:28 2020
Binyu,
Yes, I was just writing up this response...
OK, I logged onto WCOSS and was able to replicate the behavior you
describe.
Here's what I found...
met-9.1_beta2 does run with this data but met-9.1 does not. But that's
because there is a bug in met-9.1_beta2 that was fixed in met-9.1.
Take a look at this line in point_stat.cc:
https://github.com/dtcenter/MET/blob/2c9ae440a84024fbf62caa64c1b747f9a912236f/met/src/tools/core/point_stat/point_stat.cc#L861
The bug in beta2 caused this logic not be enforced because "is_vgrd"
never
evaluated to true.
But the real point here is that by convention, MET expects that when
processing winds as vectors, each point observation of UGRD is
immediately
followed by a VGRD observation at the same level. We enforce this
requirement to avoid the need of wasting processing time searching
through
all the U/V pairs to match them up. In the data you passed to
point_stat
your have 175 observations of UGRD followed by 175 observations of
VGRD. It
just so happens that the order of the levels in both is identical...
but
met-9.1_beta2 didn't actually check that to be sure! So if you made a
mistake in that regard, met-9.1_beta2 would not have caught it.
To test things out, I reordered your data to interleave UGRD and VGRD
for
each level. And the resulting file ran fine through point_stat. I've
attached that NetCDF file here.
Hope that helps clarify.
Thanks,
John

John,
Thank you. More questions here:
1. I finished running the verification using 9.1_beta2. Should I rerun
them
using 9.1? Will there be any difference for the point_stat output
between using the different versions?
2. How did you do the reorder? Here is the script I used to do
asc2nc, I
used the default config file.

Subject: wind_thresh
From: John Halley Gotway

Should you rerun with met-9.1? Generally, the beta releases are meant
for
testing new development, not production runs. I don't know of any
results
off the top of my head that would be different between beta2 and 9.1,
but
there certainly could be something. If you'd like to use beta2, it'd
be
prudent to carefully review the release notes and consider which
changes
may or may not impact your results. Or you could rerun everything with
met-9.1. Or you could just rerun a couple of example cases, diff your
results with beta2 output, and decide what you'd like to do from
there.
Listed below are the steps I ran to reorder your data. But I
definitely
don't recommend this as a general purpose way of doing this. Instead,
it's
just a hack I used for testing, and it was only for U/V obs, not other
obs
in the file.
# Run Rscript to dump existing NetCDF file to ascii (probably won't
work on
wcoss because the ncdf4 library probably doesn't exist)
Rscript
/Volumes/d1/projects/MET/MET_development/MET-
develop/met/scripts/Rscripts/pntnc2ascii.R
asc2nc_PANO_20200203t12Z.nc > asc2nc_PANO_20200203t12Z.txt
# Subset the UGRD and VGRD obs into separate files
grep UGRD asc2nc_PANO_20200203t12Z.txt >
asc2nc_PANO_20200203t12Z_UGRD.txt
grep VGRD asc2nc_PANO_20200203t12Z.txt >
asc2nc_PANO_20200203t12Z_VGRD.txt
# Run the paste command to stitch them back together
paste -d
"\n" asc2nc_PANO_20200203t12Z_UGRD.txt
asc2nc_PANO_20200203t12Z_VGRD.txt
> asc2nc_PANO_20200203t12Z_sorted.txt
# Run ascii2nc to regenerate NetCDF output
ascii2nc asc2nc_PANO_20200203t12Z_sorted.txt

Subject: wind_thresh
From: binyu.wang at noaa.gov
Time: Thu Aug 27 17:00:11 2020
Got it, thank you very much!
Before you are very tired of answering my questions, there is one more
from
two weeks ago:
I tried to do gefs verification by using prepbufr data. Unfortunately
I
always got "0 matching pair" when I applied PB2NC and ensemble_stat.
Here
is the directory:
cd
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ecf
% ./test_bufr.ecf >& bufr.log3
I tried to diagnose the problem by converting the prepbufr data to
grid
data using point_to_grid, the script is:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/Scripts/MET/pt2grid.sh
One of the output is:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ush/COMOUT/
regrid.prebufr.nc.txt
It seems the PRES field does not look correct to me: it is over
~20000mb,
which is impossible. I confirmed with prepbufr people, the unit inside
of
the prepbufr is mb, and the magnitude should be <1000mb. But I can not
find
where the error is. Any suggestions?

Subject: wind_thresh
From: John Halley Gotway
Time: Fri Aug 28 14:28:47 2020
Binyu,
OK I'm taking a look in this log file:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ecf/bufr.log3
Whenever folks get 0 matched pairs from Point-Stat, I always advise
that
they increase the verbosity level to list out counts of reason codes
explaining why obs were or were not used, such as below:
DEBUG 3: Number of matched pairs = 132
DEBUG 3: Observations processed = 89893
DEBUG 3: Rejected: station id = 0
DEBUG 3: Rejected: obs type = 79788
DEBUG 3: Rejected: valid time = 0
DEBUG 3: Rejected: bad obs value = 0
DEBUG 3: Rejected: off the grid = 5
DEBUG 3: Rejected: topography = 0
DEBUG 3: Rejected: level mismatch = 9219
DEBUG 3: Rejected: quality marker = 0
DEBUG 3: Rejected: message type = 344
DEBUG 3: Rejected: masking region = 405
DEBUG 3: Rejected: bad fcst value = 0
DEBUG 3: Rejected: bad climo mean = 0
DEBUG 3: Rejected: bad climo stdev = 0
DEBUG 3: Rejected: duplicates = 0
Unfortunately though, Ensemble-Stat does NOT track and report the same
counts!
So I wanted to actually run Point-Stat using 1 of the ensemble members
with
those same point observations at verbosity level 3.
BUT when I logged on WCOSS, I could not actually locate those files.
So you
could either...
(1) Do this testing yourself. Run Point-Stat to compare 1 ensemble
member
to these obs and check the verbosity level 3 output to see why there
are 0
matched pairs.
(2) Or you could post the following files to our anonymous FTP site
following these instructions:
http://dtcenter.org/community-code/model-evaluation-tools-met/met-
help-desk#ftp
I'd need:
(1) Ens file:
gefs01.t00z.grid3.f12.grib2
(2) Obs file:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/com/gefs.20200203/
gdas.2020020300.prebufr.f00.nc
(3) Ensemble-Stat config file:
/gpfs/dell1/ptmp/Binyu.Wang/gens/tmpnwprd/verf_g2o_gefs_00_dev.25142/verf_g2o_ens_gens_config.bufr
Please just let me know.
Thanks,
John

Subject: wind_thresh
From: binyu.wang at noaa.gov
Time: Fri Aug 28 15:58:42 2020
Hello John,
I am sorry that some inputs are gone.
I did do a quick test as you suggested, and it seems there was no
problem,
here is the script and log file:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ush/point_stat_burf.sh
>point_stat_burf.sh.log
However, when I tried my ensemble_stat, I got same error as before,
the log
file is:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ecf/bufr.log4
All the inputs are on WCOSS now. Thank you.
Binyu

Subject: wind_thresh
From: John Halley Gotway

Binyu,
Thanks for the update log files to look investigate.
I'm looking in:
*/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ush/point_stat_burf.sh.log*
And in:
*/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ecf/bufr.log4*
Looking carefully, I see that you are using 2 different point
observation
files:
In Point-Stat:
*/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ush/COMOUT/gdas.2020020200.prebufr.f00.nc
<http://gdas.2020020200.prebufr.f00.nc>*
In Ensemble-Stat:
*/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/com/gefs.20200203/gdas.2020020300.prebufr.f00.nc
<http://gdas.2020020300.prebufr.f00.nc>*
The Point-Stat one contains *1328047* observations:
*ncdump -h
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens_g2o/ush/COMOUT/gdas.2020020200.prebufr.f00.nc
<http://gdas.2020020200.prebufr.f00.nc> | grep nobs*
While the Ensemble-Stat one only contains *193664*:
*ncdump -h
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/com/gefs.20200203/gdas.2020020300.prebufr.f00.nc
<http://gdas.2020020300.prebufr.f00.nc> | grep nobs*
I'd recommend testing with the same input point observation files
before
looking at anything else.
Thanks,
John
