Re: NCL runtime error: Subscript out of range, error in subscript #0

Hi Ilze,

The problem is that your WRF output file only has one timestep on it.
You read in "times" with:

   times = wrf_user_list_times(a) ; get times in the file
   ntimes = dimsizes(times) ; number of times in the file

If you print "ntimes", you will see that it is equal to 1.

Later, you have a "do" loop that is trying to access index 2 of the
times array:

   do it = 2,ntimes-1,2
. . .
     res@TimeLabel = times(it)

This is where the error is coming from.
