In this animation, the globe slowly rotates one full rotation while seasonal landcover and Arctic sea ice vary through time. The animation begins on September 21, 2005 when sea ice in the Arctic was at its minimum extent, and continues through September 20, 2006. This time period repeats six times during the animation, playing at a rate of day frame per frame. Over the terrain, monthly data from the seasonal Blue Marble Next Generation fades slowly from month to month. Over the water, Arctic sea ice changes from day to day. February 2007
