[Wrf-users] Help with GFS data to force WRF

[Barry Lynn]

Hi Jose:

I appreciate your bringing to my attention the links to these pages.
However, I will need authorization to go to the last link.

I did some checking, but I see only ways to convert GRIB to NETCDF, but not
the reverse.

If you just need 0.5 degree data, you can get reanalysis GFS data from the
site I mentioned. If it is for model runs, it should be acceptable.

Otherwise, perhaps WRFHelp can comment.

Barry
