Re: Error: Undefined identifier

Hi Guilherme,

I should to allocate memory before the loop. In other words, you should
create the array tempn before your loops. You're assign values to an array
that doesn't exist. Before the loops, insert the following line:

tempn = new( (/ dim_t, dim_lev, dim_lat, dim_lon /), float )

in which

dim_t, dim_lev, dim_lat and dim_lon are the size of dimensions of your new
array.

Best regards,

Mateus
