Abstract : Since 1987, the Fleet Numerical Meteorology and Oceanography Center (FNMOC) has been running sea ice forecasting systems in various regions of Navy interest (the Central Arctic, the Barents Sea, and the Greenland Sea). The Polar Ice Prediction System Version 1.1 predicts sea ice conditions in the Arctic basin, the Barents Sea, and the Greenland Sea at a resolution of 127km. Two regional sea ice forecast systems, the Polar Ice Prediction System - Barents Sea (RPIPS-B) and the Polar Ice Prediction System - Greenland Sea (RPIPS-G), also predict sea ice conditions in the Barents and Greenland Seas, respectively, at a higher resolution of 20-25 km. In 1995, the Naval Research Laboratory delivered to FNMOC a coupled ice ocean system, the Polar Ice Prediction System Version 2.0 (PIPS2.0), which predicts sea ice conditions for most of the ice covered regions in the Northern Hemisphere. PlPS2.0 will replace the three existing operational forecast systems when it completes the final operational testing phase at FNMOC. PIPS2.0 uses as its basis the Hibler ice model and the Cox ocean model. PIPS2.0 has a resolution of approximately a quarter of a degree, which is equivalent to the resolution of the operational regional systems (RPIPS-B and RPIPS-G). This report describes the test cases and test procedures necessary to execute PlPS2.0.
