Initial Request
----------------------------------------------------------------
Dear madam/Sir,
I wanted to make a comparison of fcst. vs obs. data for APCP .
While I am running mode ... tool of METV7.0, It is displaying the fcst and
obs grids do not match. Can you please suggest how to match the grids in
both fcst and obs files. I mean to say while running run_unipost_frames of
UPP what is the correct option for custom grid like 255 0 .....else any
other way to overcome this, please recommend.
The APCP_obs...nc file is an output of pcp_combine tool using ST4....
observation data(one sample data is attached)
Thanking You
With Best Regards

Biranchi,
Good news. This is now easily handled by setting the "regrid" section
of
the MODE config file. You can tell MODE to automatically regrid the
forecast data to the observation domain or vice-versa. Try setting:
regrid = {
to_grid = FCST; // or set to OBS
method = BUDGET;
width = 2;
vld_thresh = 0.5;
shape = SQUARE;
}
This will regrid the forecast data to the observation domain. I chose
BUDGET (mass-conserving) interpolation since you're processing precip.
You can read more about the "regrid" options in the MET User's Guide.
Thanks,
John Halley Gotway

Dear sir,
Your suggestion works fine for stage 2 and stage 4 precipitation
analysis
which are in grib formats and the .txt, .nc files created nicely with
0
fcst and 0 obs. This is probably due to the difference of domain.
I mean to say that, my fcst files cover the portions of Bay of Bengal,
but
the st2 and st4 analysis data covers some other domain. TRMM data is
not
available in grib formats rather in .bin or .nc4 formats. So i could
not
run mode tool using TRMM data.
Is there any other way to overcome this ?

Biranchi,
Here's a link on the MET website to a page about data sources... which
mentions TRMM:
https://dtcenter.org/met/users/downloads/observation_data.php
And here's a link to TRMM data that available in NetCDF format:
https://disc.gsfc.nasa.gov/datasets?keywords=%223B42%22%20%223%20hours%22&start=1920-
01-01&end=2016-06-27
TRMM is available in 3-hour and 24-hour accumulation intervals.
After
getting my username and password correct, I was able to download a
sample
data file. And to make it easy for you I posted that sample file to
this
ftp site:
ftp://ftp.rap.ucar.edu/incoming/irap/met_help/for_mahala_data/3B42.20170807.00.7.nc
Try running these commands:
wget
ftp://ftp.rap.ucar.edu/incoming/irap/met_help/for_mahala_data/3B42.20170807.00.7.nc
plot_data_plane 3B42.20170807.00.7.nc 3B42.20170807.00.7_pcp.ps
'name="pcp"; level="(0,*,*)"; file_type=NETCDF_NCCF;'
convert -rotate 90 -background white -flatten
3B42.20170807.00.7_pcp.ps
3B42.20170807.00.7_pcp.png
I've attached the resulting png image which shows that MET is able to
read
this TRMM data, which does cover the Bay of Bengal. You could compare
this
TRMM data against your model output, using the "regrid" section of the
config file to regrid the TRMM observations to your model domain...
(e.g.
to_grid = FCST;).
Hope that helps get you started.
Thanks,
John

Sir,
Thank you for your kind response and advise.
As per your advise, I ran plot_data_plane with an .nc file of TRMM and
it
works fine.
But, while running the mode command using the option as;
mode APCP_fcst_3h_val00utcMay.nc 3B42.20170530.00.7.nc
<http://3b42.20170530.00.7.nc/> MODEConfig_file
I am getting the following :
DEBUG 1: Default Config File:
/WRF_tools/met_7.0/share/met/config/MODEConfig_default
DEBUG 1: Match Config File: MODEConfig_file
DEBUG 1: Merge Config File: MODEConfig_file
ERROR :
ERROR : Trouble reading observation file "3B42.20170530.00.7.nc
<http://3b42.20170530.00.7.nc/>"
ERROR :
HDF5-DIAG: Error detected in HDF5 (1.10.2) thread 0:
#000: H5T.c line 1734 in H5Tclose(): not a datatype
major: Invalid arguments to routine
minor: Inappropriate type
NetCDF: HDF error
file: ncFile.cpp line:33
I am sending herewith the MODEConfig_file and the fcst and obs files
for
your reference.
Once again thank you very much for your efforts to my queries.
Thanking You
With Best Regards

Biranchi,
Please try using the attached MODE configuration file with this data.
/usr/local/met-7.0/bin/mode APCP_fcst_3h_val00utcMay.nc
3B42.20170807.00.7.nc MODEConfig_file
You'll see a warning message about the timestamps not matching, but
MODE
will still run and produce output (see attached).
In the attached config file, I put the entries for the object
definition
back into the "fcst" section. Then I copied them over to the "obs" by
saying "obs = fcst"... and then I listed "obs" again to define the
field
name.
Your original issue was caused by the context level at which
"file_type"
was defined. MODE parses it from the "fcst" and "obs" dictionary...
not
the "field" dictionary inside them. Once we put it at the expected
context
level, it works fine. I realize though that that's confusing!
Thanks,
John
