[ncl-talk] the script runs forever ,how to optimize ?

[Alan Brammer]

I didn't account for your time dimension. I don't see a wrf_interp function
that will interp across those two dimensions (time|level).  You could
create an output array of ntime x noutlevel and loop over times.

These lines are example and not intended to work without editing.

rhp= new( (/ntimes, 3/), float)

do t=0,ntimes-1
rhp(t,:) = wrf_interp_1d(rh(t,:,60,41), p(t,:,60,41), (/500,850,1000/))
end do

The error line tells you about the number of dimensions and the specific
problem.

P.s. always reply to ncl-talk, this allows everyone to help and not burden
a specific person.
