Hi,

In running regrid_data_plane with MET v5.2, I encounter the error:

MetGrib2DataFile::data_plane() found unrecognized grid definition (40)


This problem appears to be unique to the GEFS reforecast from ESRL (
https://www.esrl.noaa.gov/psd/forecasts/reforecast2/).  A test with a NAM
analysis grib file worked fine.

Any idea what's going on here?

Thanks,
Ryan

Hi Ryan,

Thanks for pointing out this issue you ran into.  And thanks for
sending
the link to that dataset.  I grabbed a sample file and used wgrib2 to
dump
some info about it:

wget
http://portal.nersc.gov/project/refcst/v2/downloads/2017020500_c00_0-
0hrs.grib2.tar

wgrib2 -d 1 -V 2017020500.c00/gfs_fhr00.c00.grib2
1:0:vt=2017020500:mean sea level:anl:PRES Pressure [Pa]:
    ndata=294912:undef=0:mean=101112:min=96157:max=104067
    grid_template=40:winds(N/S):
        Gaussian grid: (768 x 384) units 1e-06 input WE:NS output
WE:SN
        number of latitudes between pole-equator=192 #points=294912
        lat 89.642000 to -89.642000
        lon 0.000000 to 359.531000 by 0.469000

Running met-5.2, I'm able to replicate the error message you're
getting:

> met-5.2/bin/plot_data_plane 2017020500.c00/gfs_fhr00.c00.grib2
tmp_p500.ps
'name="TMP"; level="P500";'
DEBUG 1: Opening data file: 2017020500.c00/gfs_fhr00.c00.grib2
ERROR  :
ERROR  : MetGrib2DataFile::data_plane() found unrecognized grid
definition
(40)
ERROR  :

However, when I run met-6.1 (or the current met-7.0), the error goes
away:
> met-6.1/bin/plot_data_plane 2017020500.c00/gfs_fhr00.c00.grib2
tmp_p500.ps
'name="TMP"; level="P500";'
And I've attached a png version of the resulting image.

Checking the release notes (
https://dtcenter.org/met/users/support/release_notes/METv6.1_release_notes.php)
I see that support for Gaussian grids was added in version 6.1 or MET.

Thanks,
John

Hi John,

Thanks for the quick response!  I may or may not upgrade - my time on
this
project is coming to a close and this last verification step may not
even
be necessary.  But at least I know how to resolve the issue!

Ryan
