Transformation auxiliary data files

The mapping files to be used for the MAPPING option must be consistent with the files generated by the SCRIP library to be used for the SCRIPR transformations (see also section [*]). The files are NetCDF containing the following fields:

dimensions:
      src_grid_size = xxx ;
      dst_grid_size = xxx ;
      num_links = xxx ;
      num_wgts = xxx ;
variables:
      int src_address(num_links) 
      int dst_address(num_links) 
      double remap_matrix(num_links, num_wgts)
