Re: tips to unstagger data from WRF

Hi Erik-
It appears you can use the functions for WRF:
wrf_user_getvar to get unstaggered wind vector components

But it also looks like you need to use wrf_uvmet to get those components
to Earth relative coordinates.

I havent tried this yet but I need to. Any advice out there?
