[ncl-talk] sign_f90 slow down work flow

[Paolina Bongioannini Cerlini]

Hi NCL people,

I am working with this script attached that reads 81 netcdf files-and extracting a 
variable from them is already slow-
then I added the sign_f90 function to compute another variable, and it is lasting forever.
I am sure that ther is a better way to apply this function without entering this
4 indexes loop, but I don't see how. 
Can you help me?
Thank you.

Paolina
