The NPS 18 km Stand-Alone Sea Ice Model The NPS 18 km resolution Stand-Alone Sea Ice Model includes: A switch for using viscous-plastic ice rheology of Hibler (1979) with more efficient numerics of Zhang and Hibler (1997) or using elastic-viscous-plastic ice rheology of Hunke and Dukowicz (1997).  Parkinson/Washington (1979) surface heat budgets. Zero-layer thermodynamics of Semtner (1976). Atmospheric forcing: 1983-1984 3-daily mean ECMWF reanalysis data.  Specifically 10 m winds, 2 m temperature and dewpoint, surface downward longwave and shortwave radiation. Oceanic forcing: 1983-1984 3-daily mean output from the NPS 18 km coupled ice-ocean model.  Specifically, 10 m (first level) Temperature and Salinity, 32.5 m (2nd level) u and v velocities. back to the top back to the PIPS Homepage This is an official U.S. Navy Web site.
