Hmm, I'll rig up a similar pqact and see what I see on my end.
I don't think GEMPAK should have any problem reading a 2GB grid, as long as you
are using a 64-bit version of the software on a 64-bit OS. We can read from
HRRR GEMPAK files that are typically of size 2.2-2.5 GB without any problem ...
The "can not decode" errors are just from GRIB2 fields that don't have a match
in the grib tables in $GEMTBL/grid ... with a little research those ought to be
able to be resolved.

I am not sure if I am supposed to reply to all, but it appears to be a decoding
problem, although I am not sure what is causing it.
The file is piped through the LDM via this action, which should work.
NGRID|CONDUIT (^[LM].B... KWBE|prod/nam.*awip12)
PIPE /opt/gempak/GEMPAK7/os/linux64/bin/dcgrib2 -d
/atmo/data/gempak/logs/dcgrib2_NAM218.log
-e GEMTBL=/opt/gempak/GEMPAK7/gempak/tables
We're also starting to store data in grib2 format data as well. I figured I
could just write another action.
CONDUIT prod/nam\.(........)/nam\.t(..)z\.awip12(..)
FILE -log /atmo/data/gempak/model/nam12km/grib2/\1\2_fh_\3.grib2
which appears to be working.
Here is small part of my log for the decoding into gem format.

Hi Charles,
My guess is that the GEMPAK grid did not get created properly. Its header
might be correct, which is why gdinfo shows it, but it may not have any
meaningful information in it so none of the plotting programs work.
What version of GEMPAK are you running? Did you create the GEMPAK grid file
yourself (i.e. using dcgrib2 or nagrib2 from the GRIB2 file) or is it
automatically received in your department?
If you have IDV, try pointing it to that grid file and see if it can display
anything.

Subject: [gembud] gdlist gdplot2 problems
Hello,
I am trying to plot some basic grids with gdplot2, although I have run into
some trouble.
I first used gdinfo to see if the grid existed and I believe it does in my
attached terminal output.
However, when I run gdlist on the same exact arguments, I receive this error
[DG -7] Input grid TMPK ^140430/1800F084 @500 %PRES cannot be found.
which doesn't make any sense because GDINFO shows the grid in this file.
Does anyone have any idea what I am doing wrong?
I receive the same error in gdplot2.
Thanks,
Charles
