Once the steps in Section 3.5 have been taken, make a copy of script run_mom, change pathnames to point appropriately and add the desired options from Part XIV. Any options used in scripts run_grids and run_topog must also be included in the run_mom script. If not executing on a CRAY T90, try using option sgi, option cray_ymp, or option cray_c90 in script run_mom. To keep things simple, make a short test run with options time_step_monitor,snapshots and netcdf to produce a snapshot of the data. Have a look at the data using Ferret (Section 38). After a successful test run, enable the desired diagnostic options and disable option timing.
