Initial Request
----------------------------------------------------------------
Hi,
We tried to use MET to validate the simulation results of wrf against the observation from ncep gdas prepburf files.
We have used CONUS.poly for mask_poly (since our simulation is in CONUS) and choose "mask_grid[] = [ ];". Is
this correct?
Thanks,
Shujia

Shujia,
You are correct. You can use the following two settings in your
point_stat config file to mask out only PrepBUFR
observations over conus:
mask_grid[] = [ ];
mask_poly[] = [ "MET_BASE/data/poly/CONUS.poly" ];
Please let us know if you have any other questions.
Thanks,
Paul

Hello Paul,
Thank you for the quick reply. We do have several other questions. In
order to compare our WRF results with the observations using the MET
program, we:
1) use "p_interp" to put the WRF output into the pressure level, the
namelist.pinterp looks:
--------------------------
path_to_output = '.'
process = 'all'
fields = 'U, V, T2, SMOIS, QVAPOR'
/
met_em_output = .TRUE.
split_output = .TRUE.
debug = .TRUE.
bit64 = .TRUE.
! process can be "all", "list", "all_list"
! "all" - process all fields in file
! diagnostics PRES, TT, GHT, RH are also calculated
! "list" - list fields required in "fields"
! available diagnostics are PRES, TT, GHT, RH
&interp_in
interp_levels = 1000.,987.5,975.,962.5,950.,937.5,925.,
900.,875.,850.,825.,800.,750.,700.,650.,
600.,550.,500.,450.,400.,350.,300.,250.,
225.,200.,175.,150.,137.5,125.,112.5,100.,
87.5,75.,62.5,50.,37.5,25.,12.5,
/
extrapolate = 1,
interp_method = 2,
unstagger_grid = .TRUE.
---------------------------------
Here we use the default 38 pressure levels for interpolation. Is it
properly written?
2) use "pb2nc" to convert the GRIB observation file into a netcdf
file. In the configure file, what should we put in the message_type[
]? We want to compare the model results at surface, 850 mb, 500 mb,
and 300 mb to the corresponding observations. Will the "ADPSFC"
suffice or both "ADPSFC" and "ADPUPA" be included? In other words, do
the "ADPSFC" data include upper level measurements or just the surface
observation?
3) use "point_stat" to do the point comparison. If we want to compare
wind at 850 mb, should we do:
fcst_field[ ] = ["UU(0,9,*,*)", "VV(0,9,*,*)"]
obs_field[ ] = ["WIND/P850", "WDIR/P850"]
Note that 850 mb is the 10th element in the interp_levels array. Does
the array index start at "0" or at "1"? Does the "0" in the UU array
represents the time step 1?
In addition, does "TMP/Z2" represent the temperature at 2 m?
The threshold set in fcst_thresh seems not to work properly. E.g., we
set the threshold of TMP/Z2 as "gt300", but the mean tmp is around 295
K from the point_stat output. Is there anything wrong?
Again, for message_tpe[ ], should we put both "ADPSFC" and "ADPUPA" in
order to compares data at both surface and upper air (e.g., 850 mb)?
We highly appreciate your quick response.

Zhining,
1. Regarding p_interp, I do not know very much about this software.
I think the best approach would be to test your
model output using point_stat and then make adjustments to
namelist.pinterp if necessary. If you need help with
p_interp, please contact WRF help at wrfhelp at ucar.edu.
2. If you are interested in using observations both from the surface
and upper air, you must use both message types
"ADPSFC" and "ADPUPA". Try:
message_type[] = [ "ADPUPA", "ADPSFC" ];
or, you could also use:
message_type[] = [ "ANYSFC" ];
See the PointsStatConfig message_type comments for more details.
3.
> Does the array index start at "0" or at "1"?
0
> Does the "0" in the UU array represents the time step 1?
It depends on how p_interp output is set up, but probably.
> In addition, does "TMP/Z2" represent the temperature at 2 m?
Yes
The fcst_thresh setting is used to build contingency tables for the
data, not to perform conditional verification.
Conditional verification is not supported in MET at this time.
Please let me know if you have any other questions.

Does the array index start at "0" or at "1"? Does the "0" in the UU
array represents the time step 1?
