[gradsusr] GRIB2 and GrADS

[Frost, Mr. Michael]

Hi:

I have a bunch of individual GRIB2 files that I cat together to make one large one.  The files in question are geopotential height and different pressure levels.  All files are for the same bastime/tau and are for the same domain.

When I use the grb2ctl.pl to create the control file, it lists out each of the different levels as basically different parameters.   That is, it says I have many one level parameters, instead of 1 parameter with many levels.

Any idea on where I screwed up?

Thanks,
Mike Frost
