The coupled CICE model requires a minimum of three files to run:
Depending on the grid selected in the scripts, the appropriate global*
and iced* files will be used in the executable directory. These files
are read directory from the system input data directory and not copied
to the executable directory. Currently, only gx3v7, gx1v6, tx1v1, and tx0.1v2
grids are supported for the ice and ocean models. Note that these files can
now be used in netCDF format.
