This animation is part of an NSF-funded, international project, Exploring Time. The two-hour television special, broadcast on the Discovery Channel in the spring of 2007, explores how the world changes over different timescales ... from billionths of seconds to billions of years. This animation portrays a 3-day moving average of AMSR-E sea surface temperature (SST) over the western hemisphere from the beginning of 2005 to early December, 2006. In addition, seasonal MODIS land cover shows the advance and retreat of snow over the northern hemisphere.
This program was also broadcast in Japan through a partnership with the NHK international broadcasting service and in France through a partnership with the ARTE television network.
