8    Preprocessed OceanInversion input files are available
9    under directories region_mask, takahashi, and
10    atm_co2 in this package.  All netcdf input files
11    have been converted to binary format in order to avoid
12    having to link netcdf library with MITgcm code.  See
13    respective README files in each directory for details.
