Re: Getting 10m Winds out of NARR data

Hi all,

I responded to Don off-line, and should have responded to the group.

I suggested he try coordinate subscripting:

     nU10 = f->U_GRD_221_HTGL({10},:,:)
     nV10 = f->V_GRD_221_HTGL({10},:,:)

This will only work if you have coordinate arrays attached to the
variables on the file.
He said this worked for him.
