Abstract:

The Canadian Sea Ice Atlas from Microwave Remotely Sensed Imagery was one of Canada's contributions to the United Nations International Space Year (ISY)-1992. The Sea Ice Atlas was funded by the Atmospheric Environment Service (AES) [now Meteorological Service of Canada (MSC)] Canadian Climate Centre, the Canadian Space Agency (CSA), the Institute for Space and Terrestrial Science (ISTS), and private industry. The sea ice atlas consists of monthly total sea ice concentrations from July 1987 to June 1990 using data from the Special Sensor Microwave/Imager (SSM/I) instrument on the U.S. Defense Meteorological Satellite Program (DMSP) polar orbiting satellites. The sea ice concentration was derived using the AES/York sea ice concentration algorithm. The satellite maps are presented in two formats: for each month, the total sea ice concentration is shown with a color scheme that roughly parallels the color spectrum from red (100% ice cover) to blue (0% ice cover). For the months of February and September, which represent the maximum and minimum sea ice extent, a second representation is shown in which per cent ice cover by category is shown. The categories are thin ice, first-year ice and multi-year ice.
