Abstract :
This paper presents results comparing digitized sea-ice charts with passive microwave estimates of sea-ice concentration using the NASA Team algorithm. The Canadian ice chart series contains detailed information on sea-ice type during the sea ice growth, consolidation and melt stages for four main ice-covered regions of Canada: the Canadian East Coast, Hudson Bay, East Canadian Arctic and the West Canadian Arctic. Comparison with passive microwave sea-ice concentration estimates over the 1979 to 1996 period shows the consistency with which sea-ice concentration and sea-ice area are underestimated by the passive microwave data during melt and freeze-up conditions.
