[Met_help] [rt.rap.ucar.edu #94051] History for ensemble field not found

Wed Apr 1 11:09:27 MDT 2020

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

Hello,

I have a question with using MET for ensemble verification, would you 
please help taking a look at the error in the log file under the 
directory below:

cd
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens/ush

% /verf_kasa_volc.sh >& log

It looks there is problem with the config file at:

/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens/parm/verf_vol_ens_stat_config

Should the "field" in the "ens" directory be the same as the one in the 
"fcst" directory?

Another question: what should be set for level for forecast data? Is 
this correct?

level  = [ "L0-20000" ];

Thank you very much!

Binyu

Hi Binyu.

I have assigned your ticket to John Halley Gotway, who is likely best
able
to assist you.  Please allow a few business days for a response.

Thank you.

Julie

Binyu,

OK, I'm looking on WCOSS at this log file:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens/ush/log

And in there, I see this type of warning message:
WARNING: process_n_vld() -> ensemble field "VAFTDL0-20000" not found
in
file
"/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/Kasatochi/Obs/Hysplit/
cgrib2.001.nc"

So Ensemble-Stat is telling us it can find the requested data.  When
using
NetCDF input for the MET tools, you set name = "NetCDF Variable Name"
and
level = "Dimension Indices to Retrieve a 2D field of data".  I always
use
plot_data_plane to test this sort of thing.

# Load MET 8.1 module
module use /global/noscrub/Julie.Prestopnik/modulefiles
module load met/8.1

# Run ncdump to figure out the variable name
ncdump -h
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/Kasatochi/Obs/Hysplit/
cgrib2.001.nc | grep "float "
...
float VAFTD_L20000-0(lat, lon) ;

# Run plot_data_plane to visualize this data
plot_data_plane
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/Kasatochi/Obs/Hysplit/
cgrib2.001.nc cgrib2.001.ps 'name="VAFTD_L20000-0"; level="(*,*)";'

# That runs fine, so just update your Ensemble-Stat config file with
these
settings:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/grid2grid/verf_met_ens/parm/verf_vol_ens_stat_config

        name       = "VAFTD_L20000-0";
        level      = [ "(*,*)" ];

So you're running the output of regrid_data_plane through Ensemble-
Stat.
Note that when you run regrid_data_plane, you can rename the output
variable however you'd like using the "-name" command line option.
For
example, is you add "-name VAFTD" then the output NetCDF variable will
be
written as "VAFTD" instead of "VAFTD_L20000-0".  So you can choose
whatever
name you prefer.

Next, you're comparing this to gridded analyses from this file:
/gpfs/dell2/emc/modeling/noscrub/Binyu.Wang/MET/Kasatochi/Obs/Kasatochi_2008221-
070500_2008221-152000_MET.nc

And I see you're requesting ASH_MASS_LOADING from that file.  And it
looks
like that variable does exist.  So that should work fine.

Hope that helps.

Thanks,
John
