However, MODIS can only take measurements of the surface in daylight, cloud-free areas. For this animation, valid snowcover measurements are retained over time during darkness or cloudy days until a subsequent valid measurement is found. This animation shows the dynamic advance and retreat of MODIS daily snow cover from September 1, 2002 through September 20, 2008.    This animation shows a time series of global snow cover from 2002/09/01 through 2008/09/20.
