[Met_help] [rt.rap.ucar.edu #93160] History for RAIN_SUM in Grid-Stat

Tue Nov 19 11:53:29 MST 2019

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

I have a new problem. I need to extract the "RAIN_SUM" variable from my
wrfout files to compare it to the "est_prcp" variable in the
"ARC2_data_1-Jul_31-Jul_0p25_Camer.nc" file and fill in my contingency
table. I tried to edit the file "GridStatConfig_pw" that I renamed
"GridStatConfig_precip". When I try to run "run_gs.sh" which I also modify,
I get the error:

/home/dores/Tutorial_Master/TP_Prevision/MET/8.1/bin/grid_stat

I sent the file "ARC2_data_1-Jul_31-Jul_0p25_Camer.nc" in
ftp://ftp.rap.ucar.edu/incoming/irap/met_help/dores_data/
Please help me. And, if it works well , I beg you to send me the files
"GridStatConfig_precip" and "run_gs.sh" that you used, like the last time.

Thank you in advance,
Dorès

Dores,

Since this is a new issue, I created a new ticket in met_help for it.

I took a look at the NetCDF file you sent:
ARC2_data_1-Jul_31-Jul_0p25_Camer.nc

This is not in a format that MET can read.  MET is only able to read
certain flavors of NetCDF.

(1) The wrfout format used in wrfout_19_2.nc.
(2) The NetCDF Climate Forecast (CF) convention.
(3) The NetCDF output of other MET tools, like pcp_combine.

Your options are to either (1) reformat this data into a file format
MET understands or (2) write a python wrapper script to interpret this
data and utilize python embedding.

Examples of python embedding can be found here:

analysis-scripts

Thanks,
John

Hello John,

Please, how can I reformat my ARC2 data into a file format MET
understands. I
do not understand at all what to do with python, I do not master this
language.

Thank you in advance,
Dorès

Dores,

Good news.  It turns out that MET can understand this data if you tell
it
to interpret it as being CF-compliant by setting:
*   file_type = NETCDF_NCCF;*

I ran plot_data_plane to create the attached plot.

And you can find the config file and run script in this tarball:

ftp://ftp.rap.ucar.edu/incoming/irap/met_help/dores_data/dores_data_20191118.tar.gz

Hopefully this can help you get started with your own runs of MET.

Thanks,
John

Hello John,
Thank you very much for the tar file. But , I wanted to use *RAIN_SUM*
to
compare to *est_prcp*; instead, you took *pw* to compare to
*est_prcp*. And,
when I replace *pw* by *RAIN_SUM*, the output file is empty, the model
produces no results.
Thank you for helping me solve my problem.

Bets regards,
Dorès
