Initial Request
----------------------------------------------------------------
John, I generated a vx_mask file for the Baltic region. I am verifying a domain larger than the vx_mask file, using vx_mask to just verify over the nested grid. I used the following command line to create the mask:
/h/MET/bin/gen_vx_mask /home/specmdev/scratch/test/baltic1p5/PS.557WW_SC.U_DI.C_GP.GALWEM-RD_GR.C1P5KM_AR.BALTIC_DD.20180531_CY.12_FH.029_DF.GR2 /home/specmdev/scratch/test/baltic1p5/PS.557WW_SC.U_DI.C_GP.GALWEM-RD_GR.C1P5KM_AR.BALTIC_DD.20180531_CY.12_FH.029_DF.GR2 /h/data/global/WXQC/data/met/poly/baltic_1p5km.nc -type grid
I generate a vx_mask file over the correct region (verified with plot_data_plane).
I ran point_stat generate model-ob pairs for boundary model and the nest. The nest should have about 230 obs in it. Then I ran stat_anal to generate stats using obs in the nest for the outer domain. The stat anal job is below:
/h/MET/bin/stat_analysis -lookin /h/data/global/WXQC/data/met/ptstat/mdlob_pairs/baltic4/SL/test -out /h/data/global/WXQC/data/met/summary/sl_baltic4_1 -tmp_dir /h/data/global/WXQC/dat

Bob,
I see that you have a question about the -vx_mask job command option
for
the STAT-Analysis tool. The good news is that this one is pretty easy
to
solve.
If you look in the default STAT-Analysis config file, you'll see
several
filtering options as the top of the config file (model, desc,
fcst_lead,
... and so on, including vx_mask). Each of these config options has a
corresponding job command option. Setting the "vx_mask = [];" option
in
the STAT-Analysis config file is equivalent to setting the "-vx_mask"
job
command option. And the key point is that these options filter the
contents of the corresponding column of the .stat files from MET.
Let's
say you ran Point-Stat and created output for two masking regions
which are
named EAST and WEST in the .stat output file. Specifying "-vx_mask
EAST"
would filter the input data down to the lines where "VX_MASK = EAST".
You're getting 0 matched pairs when using "-vx_mask
/h/data/global/WXQC/data/met/poly/baltic_1p5km.nc" because that string
doesn't appear in the .stat files.
But what you actually want to do is filter the lat/lon of the MPR
lines.
Looking in the data/config/README file, you can do this using the
-mask_grid, -mask_poly, or -mask_sid job command options:
// "-mask_grid name"
// "-mask_poly file"
// "-mask_sid file|list" see description of "sid" entry
above
Please use "-mask_poly
/h/data/global/WXQC/data/met/poly/baltic_1p5km.nc"
to filter the MPR lines using the output of gen_vx_mask.
Hopefully that'll do what you need.
Thanks,
John

Bob,
I see that you have a question about the -vx_mask job command option
for the STAT-Analysis tool. The good news is that this one is pretty
easy to solve.
If you look in the default STAT-Analysis config file, you'll see
several filtering options as the top of the config file (model, desc,
fcst_lead, ... and so on, including vx_mask). Each of these config
options has a corresponding job command option. Setting the "vx_mask
= [];" option in the STAT-Analysis config file is equivalent to
setting the "-vx_mask" job command option. And the key point is that
these options filter the contents of the corresponding column of the
.stat files from MET. Let's say you ran Point-Stat and created output
for two masking regions which are named EAST and WEST in the .stat
output file. Specifying "-vx_mask EAST"
would filter the input data down to the lines where "VX_MASK = EAST".
You're getting 0 matched pairs when using "-vx_mask
/h/data/global/WXQC/data/met/poly/baltic_1p5km.nc" because that string
doesn't appear in the .stat files.
But what you actually want to do is filter the lat/lon of the MPR
lines.
Looking in the data/config/README file, you can do this using the
-mask_grid, -mask_poly, or -mask_sid job command options:
// "-mask_grid name"
// "-mask_poly file"
// "-mask_sid file|list" see description of "sid" entry
above
Please use "-mask_poly
/h/data/global/WXQC/data/met/poly/baltic_1p5km.nc"
to filter the MPR lines using the output of gen_vx_mask.
Hopefully that'll do what you need.
Thanks,
John

Subject: RE: [Non-DoD Source] Re: [rt.rap.ucar.edu #91234] VX_MASK Throwing all data
From: robert.craig.2 at us.af.mil

John, a related question. When I compare the nested grid to the outer
grid using -mask_poly, the number of observations used is not
identical. I believe is caused by when verifying a nested grid, obs
near the edge won't be used unless there is four grid points around
the observation - bilin interpolation. When I ran point stat, the
interpolation percentage was 100% so all grid points had to be there
for the interpolation to happen. Short of rerunning point_stat with
the interpolation percentage set to 0 so all obs in the domain are
used, is there a way MET can save off the observation IDs used in the
nested grid and use those obs in -mask_sid for the outer grid masking
to ensure I verify the nested and outer grid with the exact same set
of observations. The brute force way would be to filter the nest MPR
file to just the observation ID column, clean up the list, and then
use that in -mask_sid. Is this the only way to ensure the same number
over observations are used?
Thanks
Bob

Throwing all data
Bob,
I see that you have a question about the -vx_mask job command option
for the STAT-Analysis tool. The good news is that this one is pretty
easy to solve.
If you look in the default STAT-Analysis config file, you'll see
several filtering options as the top of the config file (model, desc,
fcst_lead, ... and so on, including vx_mask). Each of these config
options has a corresponding job command option. Setting the "vx_mask
= [];" option in the STAT-Analysis config file is equivalent to
setting the "-vx_mask" job command option. And the key point is that
these options filter the contents of the corresponding column of the
.stat files from MET. Let's say you ran Point-Stat and created output
for two masking regions which are named EAST and WEST in the .stat
output file. Specifying "-vx_mask EAST"
would filter the input data down to the lines where "VX_MASK = EAST".
You're getting 0 matched pairs when using "-vx_mask
/h/data/global/WXQC/data/met/poly/baltic_1p5km.nc" because that string
doesn't appear in the .stat files.
But what you actually want to do is filter the lat/lon of the MPR
lines.
Looking in the data/config/README file, you can do this using the
-mask_grid, -mask_poly, or -mask_sid job command options:
// "-mask_grid name"
// "-mask_poly file"
// "-mask_sid file|list" see description of "sid" entry
above
Please use "-mask_poly
/h/data/global/WXQC/data/met/poly/baltic_1p5km.nc"
to filter the MPR lines using the output of gen_vx_mask.
Hopefully that'll do what you need.
Thanks,
John

Subject: VX_MASK Throwing all data
From: John Halley Gotway
Time: Thu Jul 25 11:54:58 2019
Bob,
Yes, your explanation makes sense. Edge effects can be a pain. So
let me
clarify what it sounds like you're doing:
(1) You ran Point-Stat on the parent domain and wrote MPR output.
(2) You ran Point-Stat on a nested domain and wrote MPR output (using
a
subset of the obs used for the parent).
(3) You're running STAT-Analysis on the MPR lines from (1) and would
like
to subset them down to the stations which are used in the MPR lines
from
(2).
I assume this approach is to answer the question, how do the vx scores
of
the parent domain compare to the vx scores of the nest, using the
exact
same set of observations?
Without rerunning Point-Stat, then yes, I agree with you. The best
way to
have fine control over which stations are or are not included is using
the
"mask_sid" option. In met-8.1, the OBS_SID is stored in the 27-th
column.
So the following sort of command would ignore the header and print the
unique SID locations:
egrep -v "VERSION" sample_mpr.txt | awk '{print $27}' | sort -u
Thanks,
John

Subject: VX_MASK Throwing all data
From: John Halley Gotway
Time: Fri Jul 26 10:19:34 2019
John,
No, there's no obvious alternative way of handling this better with
met-8.1.
But I did have a couple of thoughts on the way into work today. The
mask
section in Point-Stat contains 3 entries for defining masking regions.
But
there is a subtle difference between them:
- The grid and poly options are "area" masks, meaning they define
which
FORECAST grid points should be included in the verification region.
Any
forecast grid points outside those regions are considered to contain
bad
data values.
- The sid and llpnt entries are "point" masks, meaning they define
which
point OBSERVATIONS should be used. The mask.sid option specifies the
list
of station names while the mask.llpnt option defines thresholds for
the
lat/lon values (with no consideration given to the grid on which the
vx is
done).
These sort of details matter a lot when dealing with edge effects.
The
appeal of the mask.grid and mask.poly options is that the same logic
for
them is applied consistently throughout the MET tools (in Point-Stat
and
Grid-Stat, in particular). But perhaps there's room to add more
masking
options which would apply the grid and poly masking logic to the point
OBSERVATION locations instead of the forecast grid points.
For example, "gridpnt" and "polypnt" could mean "use point
observations
falling inside these regions". And don't apply them in any way to the
gridded forecast data. I *think* this logic would make it easier to
compare the performance of the nest to the parent using the same set
of
point observations... basically solving the edge effect issue.
But this would require new development. We met with Evan and crew
yesterday to discuss how to handle these sort of ideas that come up
during
met-help support. We could document it in a GitHub issue with AF's
name on
it, but leave it un-prioritized and discuss it further with you guys.
Is this enhancement worth documenting in this way? Or is it overkill?
Thanks,
John

John, I think it would be a very help full addition. We do
comparisons of nested models all the time an want to have the same obs
used for the computation of statistics.

Throwing all data
John,
No, there's no obvious alternative way of handling this better with
met-8.1.
But I did have a couple of thoughts on the way into work today. The
mask section in Point-Stat contains 3 entries for defining masking
regions. But there is a subtle difference between them:
- The grid and poly options are "area" masks, meaning they define
which FORECAST grid points should be included in the verification
region. Any forecast grid points outside those regions are considered
to contain bad data values.
- The sid and llpnt entries are "point" masks, meaning they define
which point OBSERVATIONS should be used. The mask.sid option
specifies the list of station names while the mask.llpnt option
defines thresholds for the lat/lon values (with no consideration given
to the grid on which the vx is done).
These sort of details matter a lot when dealing with edge effects.
The appeal of the mask.grid and mask.poly options is that the same
logic for them is applied consistently throughout the MET tools (in
Point-Stat and Grid-Stat, in particular). But perhaps there's room to
add more masking options which would apply the grid and poly masking
logic to the point OBSERVATION locations instead of the forecast grid
points.
For example, "gridpnt" and "polypnt" could mean "use point
observations falling inside these regions". And don't apply them in
any way to the gridded forecast data. I *think* this logic would make
it easier to compare the performance of the nest to the parent using
the same set of point observations... basically solving the edge
effect issue.
But this would require new development. We met with Evan and crew
yesterday to discuss how to handle these sort of ideas that come up
during met-help support. We could document it in a GitHub issue with
AF's name on it, but leave it un-prioritized and discuss it further
with you guys.
Is this enhancement worth documenting in this way? Or is it overkill?
Thanks,
John

Bob,
OK, I made this GitHub development issue and will resolve this ticket:
https://github.com/NCAR/MET/issues/1179
Thanks,
John
