Daily Snow over North America 2002-2003 with Permafrost Map

This animation shows daily snow cover over North America from September 1, 2002 through June 30, 2003. A permafrost map shown in frost-green indicates where the ground is frozen throughout the year. The sea ice climatology indicates the average extent of the sea ice during each month.
