Global Sea-Ice Analysis System

Environment and Climate Change Canada provides global sea-ice analysis fields produced by its operational Global Deterministic Prediction System (GDPS) and interpolated to a rotated latitude-longitude grid with 0.09 x 0.09 degree resolution. The data files are in NetCDF format (NetCDF-4 classic model) and comply with the Climate and Forecast Conventions. The Global Sea-Ice Analysis System is an analysis system based on 3D-Var assimilation covering all waters (ocean and lakes) at a 10km horizontal resolution on a YIN-YANG grid and using a 6 hours persistence forecast for the background state. This analysis assimilates 4 times a day satellite remote sensing data and Canadian Ice Service ice charts.
