Re: question about wrf_user_getvar

Hi,

Please see:

http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml

for a list of quantities that you can retrieve using wrf_user_getvar.
"U" and "V" are not in this list.

If you are just trying to get U and V off the file, you can do this
directly:

   U = a->U
   V = a->V
