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

To Whom It May concern:

I run into problem using grid_stat, the specification of "level" leads to
error message of

No matching record found for 'AOTK/L0'

The error message is
/naqfc/save/Ho-Chun.Huang/grid2grid/EMC_verif_aq_g2g/working/test.log,
starting line 41840.

The configuration file is
/naqfc/save/Ho-Chun.Huang/grid2grid/EMC_verif_aq_g2g/parm/verf_g2g_config_cmaqaod

Model file is,
.e.g., /gpfs/hps/nco/ops/com/aqm/prod/aqm.20190908/aqm.t06z.aot.f41.148.grib2

> wgrib2 -V

        North Pole (442 x 265) Dx 12000.000000 m Dy 12000.000000 m mode 8

Perry noticed it is on sigma level.

Can grid-stat handle this aot file or it need to be converted to MET_netCDF?

Thank you for your help.

best regards,
Ho-Chun

Ho-Chun,

Thanks for pointing me to the error message you're getting and where
the
input data lives!

Turns out this one is easy.  The answer is, just switch from using
'level="L0";' to 'level="L1";'.

By requesting "L1", we're saying we want a generic level type, meaning
we
don't care if it's a pressure level, height above ground level, height
below ground level, or even a sigma level (which it actually is, as
Perry
points out).  But the level has a VALUE of 1.  That's why "L1" works
but
"L0" does not.

Here's how I debugged on gyre using plot_data_plane (the plot is
attached):


*module use /global/noscrub/Julie.Prestopnik/modulefiles*

*module load met/8.1*

*plot_data_plane
/gpfs/hps/nco/ops/com/aqm/prod/aqm.20190908/aqm.t12z.aot.f35.148.grib2
aqm.t12z.aot.f35.148.ps <http://aqm.t12z.aot.f35.148.ps> 'name="AOTK";
level="L1";'*

Please just update your Grid-Stat config file to verify "L1" instead
of
"L0".

Thanks,
John

John:

Thank you. L1 works for reading regridded AOT nc file.  Please close
the
ticket.
