[Met_help] [rt.rap.ucar.edu #82281] History for VAL1L2 not being computed?

  Initial Request
----------------------------------------------------------------

Hi,

I'm running grid_stat to get SAL1L2 and VAL1L2 output. I have these set to
"STAT" in my config file. The SAL1L2 output is there in the config file but
the VAL1L2 isn't. I tried running again with VAL1L2 set to "BOTH" and the
_val1l2.stat file was blank, minus the header. I'm using METV6.0, so I have
my config set up where UGRD isn't followed VGRD at the same level. VL1L2
works fine this way. Does the climo file need to have a UGRD_VGRD variable
in order for VAL1L2 to be computed, or can it just used the UGRD and VGRD
variables?

Hi Mallory,

I see that you're having trouble generating VAL1L2 output from MET.

You suspect that perhaps the order of the data listed in the config
file is
impacting the result.  I re-ran some of the Point-Stat tests from our
nightly build changing the order of the variables listed in the config
file.  And it reliably computed the VAL1L2 output lines, regardless of
the
order.

However, you're running Grid-Stat, and I see that none of the nightly
build
tests actually generate VAL1L2 for Grid-Stat currently.

I think we should do two things....

(1) Rerun grid-stat using verbosity level 3 (-v 3) and writing the
result
to a log file (-v run_gs.log).  Grep the log file for climatology:
  grep climatology run_gs.log

Make sure that Grid-Stat actually found matching climo fields for the
U and
V component of winds.  If not, that's why you're not getting any
VAL1L2
output lines.

(2) I'll add a call to Grid-Stat to our nightly build tests, and while
I'm
doing that, I'll make sure that it successfully writes VAL1L2
regardless of
order of variables listed.

Thanks,
John

Mallory,

Sorry I sent that too quickly.  We actually do already have a call to
Grid-Stat which generates VAL1L2 output in our nightly build... and U
and V
are not in sequential order.

The most likely explanation for your issue is that Grid-Stat isn't
finding
matching U and V climo data for some reason.  I'd suggest looking
closely
at the log messages from Grid-Stat.

Thanks,
John

Hi John,

Thanks for checking on the nightly build, there is user error in here
somewhere then! Are the climo files you are using from the VSDB
package,
those are the ones I am using, or something else? I ran with debug 3
and
did a grep on my log file, and I can see it is finding the climo
files. And
I see is using the vector pairs ex. "DEBUG 3: Using 1311 of 1311
vector
pairs for forecast wind speed threshold NA, observation wind speed
threshold NA, and field logic UNION." and the output file name "DEBUG
1:
Output file:
/scratch4/NCEPDEV/global/save/Mallory.Row/VRFY/met/out/grid2grid/model/gfs2016/anom/00Z/grid_stat_240000L_20150702_000000V.stat".
The SAL1L2 for the winds works fine, and VL1L2 works for the vector
winds.

I am working on Theia, if you want to take a look. My log file is
"/scratch4/NCEPDEV/global/save/Mallory.Row/VRFY/met/out/grid2grid/log/compute_grid2grid_c00.out"
and my config file is at
"/scratch4/NCEPDEV/global/save/Mallory.Row/VRFY/met/config_files/GridStatConfig_anom"
