Satellites are a critical source of information for monitoring changes in Arctic climate. Space-based data have shown that the central Arctic has warmed and become cloudier in spring but cooled and become less cloudy in winter; sea ice has declined at a greater rate than that predicted by most climate models, snow cover has decreased and vegetation growth has increased, and changes in cloud cover have slowed Arctic warming.
Jeff's presentation illustrated how satellite data are used for measuring and monitoring the Arctic climate system and interactions within it, and demonstrated the critical role of satellite products in an region where in situ measurements are sparse or nonexistent.
