The Moderate Resolution Imaging Spectroradiometer (MODIS) provides data in 36 spectral bands, some of which are used to map global snow cover. 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.
