Overview:
The Global Ice Ocean Prediction System (GIOPS) provides global ice and ocean analyses and 10 day forecasts daily at 00GMT on a 1/4° resolution grid. GIOPS includes a full multivariate ocean data assimilation system that combines satellite observations of sea level anomaly and sea surface temperature (SST) together with in situ observations of temperature and salinity. In situ observations are obtained from a variety of sources including: the Argo network of autonomous profiling floats, moorings, ships of opportunity, marine mammals and research cruises. Ocean analyses are blended with sea ice analyses that combine satellite retrievals of sea ice concentration with Daily Ice Charts and RADARSAT image analyses produced by the Canadian Ice Service. Atmospheric fluxes for 10 day forecasts are calculated using fields from the Global Deterministic Prediction System.
