Great! I guess some effort by the developers needs to be placed on
finding out what the problem is with the MDGRB2 method since this seems
to be an ongoing problem ...

Hi Rob,
Out of curiousity, use the MDGDEC grib packing method in your dcgrib2 command:
e.g.
dcgrib2 -e MDMETH=MDGDEC ...
I have run into strange values in the v component of the wind before, when
using the default (MDGRB2) grib packing method, although I've only seen this
happen with global grids of v-wind on the -2 PVU surface.
The resulting GEMPAK file will be much larger than with the MDGRB2 method.
Let us know if this helps ...

Hello,
I am having difficulty correctly converting the new NAM conus nest into GEMPAK
using DCGRIB2. Most of the grids are converting correctly, however the v-wind
fields are bogus. This results in a lot of spurious calculations, including
WND. Is anyone else having this problem?
Thanks,
Rob
