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

Hi,

I've been working with John on the Jason Otkin DTC Visitor project and 
have run into an issue attempting to use the point_stat module. I'm 
getting the error:
VarInfoGrib::set_dict() - unrecognized GRIB1 field abbreviation 
'channel_9_brightness_temperature' for table version 2
when attempting to read in a NetCDF observation file using the commands:
obs = {
    field = [
       {
        name  = "channel_9_brightness_temperature";
        level = "(*,*)";
        file_type = NETCDF_MET;
        cat_thresh =  <=250.0 ;
       }
    ];
};

Do you know what is causing this issue? I've uploaded my config file, 
forecast file, and observation file to the anonymous ftp server under 
the directory griffin_data. We have been able to run the mode module 
with the NetCDF observation files on the same build of MET.

Have a great day!
Sarah

Hi Sarah.  Some of our team is on vacation and won't be back until
next
week, as opposed to later this week.  We'll keep working on a solution
and
will let you know as soon as we have one.

Thanks for your patience.

Julie

Subject: Point_Stat unable to recognize NetCDF forecast file
From: John Halley Gotway
Time: Mon Aug 17 11:17:52 2015

Hello Sarah,

I apologize for the delay in getting back to you.  I was on vacation
last
week, and am working my way through a backlog of emails this morning.

Point-Stat is used to compare a gridded forecast to point
observations.  It
can read the gridded forecast from any of the gridded data file
formats
that MET supports (GRIB1, GRIB2, and a couple flavors of NetCDF).  But
the
observations must be the NetCDF output of the ascii2nc, pb2nc, or
madis2nc
tools.

The way you setup the "fcst" section in the Point-Stat configuration
file
depends on the file format.  It's a little different for GRIB vs
NetCDF.
But the way you set up the "obs" section in the Point-Stat
configuration
file is always the same.  Rather than create our own convention for
defining variable types, we chose to use the existing GRIB1
conventions.
So you should setup the "obs" section as if it were GRIB1 data.
That's why
the NetCDF output of ascii2nc, pb2nc, and madis2nc includes a
"grib_code"
setting.

In the example you sent me, it looks like you're trying to verify
brightness temperature.  Here's the GRIB1 table defined in MET:
   http://www.nco.ncep.noaa.gov/pmb/docs/on388/table2.html

Perhaps you encoded your point observations as "Brightness
Temperature" as
GRIB code 118 from parameter table version number 2.  If so, here's
what
you'd use in the config file:

obs = {
   field = [
      {
       name  = "BRTMP";
       level = "L0";
       cat_thresh =  <=250.0 ;
      }
   ];
};

Hopefully that helps.  Just let me know if you have more issues or
questions.

Thanks,
John
