[ncl-talk] change lat lon

[Vanúcia Schumacher]

Hi NCL users,


How can I get a variable with latitude and longitude of another variable?
For example, I want var2 to have the same lat and lon of var1, without changing resolution.

I tried this way, but don't work


  minlat     = -37.44693
  maxlat    = -31.94739
  minlon    = -73.65259
  maxlon   = -66.7254

 var2_zoom  = var2(:,minlat:maxlat,minlon:maxlon)

fatal:Illegal subscript. Subscripts must be integer when not using coordinate indexing
