Re: [gembud] DCGRIB2 incorrect conversion for NAM conusnest

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
