The namelist parameters listed in Table 6 are for grid and mask information. During execution, the ice model reads grid and land mask information from the files grid_file and kmt_file that should be located in the executable directory. There are commands in the scripts that copy these files from the input data directory, rename them from global_$ICE_GRID.grid and global_$ICE_GRID.kmt to the default filenames shown in Table 6.
|grid_type||Character||'displaced_pole'||Determines grid type.|
