Canadian Sea Ice Atlas from Microwave Remotely Sensed Imagery

[ Update this Record ]

Summary
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.
