Requirements

Prior to the workshop, the participants are advised to perform a few installations of software and to prepare their own data files.

Software

  1. Compilation and execution: cygwin (if windows machine), a Fortran compiler (gfortran, ifort, …) and the netcdf library compiled with the same Fortran compiler that will be used for Diva.
  2. Visualization of results: gnuplot, ncview, ncbrowse or any other plotting software that can read NetCDF format.
  3. Processing of results and advanced plotting: matlab or octave, and a the NetCDF toolbox.

Data files

  1. One or several data files in ODV format (spreadsheet). The file may contain several variables if desired.
  2. A topography for you area of interest.
