Data Analysis Examples

Hints before you start:

  • NCL uses an array syntax similar to Fortran-90.
  • NCL has 0-based subscripts and the rightmost subscript varies fastest.
  • Fortran has 1-based subscripts, and the leftmost subscript varies fastest.
  • Do loops should be avoided, since NCL, like Matlab and IDL, is an interpreted language.
