The arctic is one of most climate sensitive areas in the world, but there is no enough polar meteorological observation data for a long time. In order to increase the weather forecast accuracy for Canada and North America, several departments of Canada, including the environment, meteorological, and defense departments, jointly launched a polar communication and meteorological satellite program (PCW: Polar Communication and Weather). The program will provide continuously communication and meteorological service and remote sensing observation for the region of over 50°N. The meteorological satellite will provide remote sensing information for the arctic region nearly every 15/30 minutes, with the emphases on the retrieval of wind fields for the high latitude region and the monitoring of sea/lake icing, snow cover, and vegetation, as well as the retrieval of clouds, aerosols, and volcanic ashes, which will play an important role in the researches on global climate changes. A brief introduction is made to the progress of the PCW program, the design, track balance, and remote sensing instruments of the satellite observation system, as well as the meteorological and space weather monitoring products and their applications.
