Re: Where oh where

It might be complicated in fortran but I dont see how that effects the where
in NCL.

You can still write:
var = where((t_ref2m .gt. 324.15) .or. (t_refm .lt. 293.15), Missing_value,
t_ref2m) ; .and. would fail since 1 grid point can not have two values

You can keep making changes to the array "var".
;code is untested
