[Met_help] [rt.rap.ucar.edu #76357] History for MODE question

Initial Request
----------------------------------------------------------------
I'm trying to run MODE to perform object-based verification of model wind speed forecasts. I'm using MET V4.1. The model output contains U and V fields only. Can MODE be run in a way to specify that the analysis/diagnostics be computed for wind speed derived from the U and V fields?
For Grid-Stat and Point-Stat, you specified U and V as well as WIND in the config file and the output for speed is calculated from U and V and then output along with the output for U and V separately. Could this same approach work for MODE?
Thanks.

Subject: MODE question
From: Raby, John W USA CIV
Time: Fri May 13 09:42:22 2016
Updated info:
I was able to get MODE to run and apparently generate wind speed
(WIND) output by modifying my config file to add specifications for
UGRD, VGRD and WIND in that order in the "fields to be verified"
section. See attached log file. The output looks normal and specifies
WIND and not UGRD or VGRD. Does this indicate valid results to you?
The field specifications I used in my config file are listed below:
// Forecast and observation fields to be verified
//
fcst = {
field = {
name = "UGRD";
level = "Z10";
};
raw_thresh = >=0.0;
conv_radius = 1;
conv_thresh = >=3.0;
vld_thresh = 0.5;
area_thresh = >=0.0;
inten_perc_value = 100;
inten_perc_thresh = >=0.0;
merge_thresh = >=1.25;
merge_flag = THRESH;
field = {
name = "VGRD";
level = "Z10";
};
raw_thresh = >=0.0;
conv_radius = 1;
conv_thresh = >=3.0;
vld_thresh = 0.5;
area_thresh = >=0.0;
inten_perc_value = 100;
inten_perc_thresh = >=0.0;
merge_thresh = >=1.25;
merge_flag = THRESH;
field = {
name = "WIND";
level = "Z10";
};
raw_thresh = >=0.0;
conv_radius = 1;
conv_thresh = >=11.0;
vld_thresh = 0.5;
area_thresh = >=0.0;
inten_perc_value = 100;
inten_perc_thresh = >=0.0;
merge_thresh = >=1.25;
merge_flag = THRESH;
};
obs = fcst;
Thanks.

I'm trying to run MODE to perform object-based verification of model
wind speed forecasts. I'm using MET V4.1. The model output contains U
and V fields only. Can MODE be run in a way to specify that the
analysis/diagnostics be computed for wind speed derived from the U and
V fields?
For Grid-Stat and Point-Stat, you specified U and V as well as WIND in
the config file and the output for speed is calculated from U and V
and then output along with the output for U and V separately. Could
this same approach work for MODE?
Thanks.

Subject: MODE question
From: John Halley Gotway
Time: Fri May 13 10:17:46 2016
John,
Yes, that is correct. When you pass the MET tools a GRIB file and
specify
a field named "WIND", it first checks to see if WIND already exists in
that
GRIB file. If so, it uses it. If not, it finds UGRD and VGRD for the
same
level and derives wind speed on the fly.
I would suggest running your MODE test case at a higher verbosity
level
(e.g. -v 3) and write the output to a log file (e.g. -log
run_mode.log).
Then inspect the log file closely and you should see some messages
about
using U and V to derive wind speed. That log message will look
something
like the following...
DEBUG 3: MetGrib1DataFile::data_plane_array() -> Attempt to derive
winds
from U and V components.
Hope that helps.
Thanks,
John

John -
Thanks for confirming the way MODE works when presented with the
"WIND" specification. I saw in my log file the following wording about
deriving the wind speed:
DEBUG 3: MetGrib1DataFile::data_plane_array() -> Attempt to derive
winds from U and V components.
Based on your explanation of the way MODE works, could I have omitted
the specifications for UGRD and VGRD in my config file and still
obtained the WIND results? (ref my original email which showed how I
modified my config file)

John,
All you need to do is request "WIND" and make no mention of UGRD and
VGRD.
MET will handle the derivation on the fly. I suspect that when you
specify
multiple settings for UGRD, VGRD, and WIND each setting is just
overriding
the previous one.
You really don't need to do this... but if you're curious, you could
turn
up the verbosity level even higher (maybe -v 5 or so). That will dump
the
contents of the parsed configuration file. My suspicion is that
you'll see
no mention of UGRD and VGRD in that dump since they were overwritten
by
WIND.

John -
This discussion about the way MODE works was very helpful. I did note
that the screen dump info never made mention of UGRD or VGRD. It only
mentioned WIND. So, I agree that it was just ignoring all but the last
specification for WIND output. Also, the output files make no mention
of UGRD or VGRD and only show data for WIND.
I'll try removing the UGRD and VGRD specs form the config file and
rerun to confirm I get the same results.
Thanks.

Subject: MODE question
From: John Halley Gotway
Time: Fri May 13 11:24:50 2016
John,
Sounds good. When you turn up that verbosity level, you sure do get a
lot
more output! But I'm glad you were able to make sense of it.
I'll go ahead and resolve this ticket. Just let us know what other
issues
or questions arise.
Thanks,
John
