Re: Want to calculate d/dy

Did you look at the example? It has everything you need.

If T is the "term" then

  T_grad_lon = T ; create arrays to hold output,
                          ; same size and type as input
  T_grad_lat = T
                          ; this procedure will overwrite
                          ; values in T_grad_lon and T_grad_lat

   gradsg (T, T_grad_lon, T_grad_lat)

   T_grad_lon@long_name = "longitudinal gradient (derivative)"
   T_grad_lat@long_name = "latitudinal gradient (derivative)"
   T_grad_lat@units = "K/m"
   T_grad_lon@units = "K/m"
   printVarSummary(T_grad_lat)

   T_grad_lat is the d/dy
