The Moderate Resolution Imaging Spectroradiometer (MODIS) provides data in 36 spectral bands, some of which are used in an algorithm to map global snow cover. The animation shows the dynamic behavior of the advance and retreat of continental snow cover in the Northern Hemisphere for the winter of 2001 - 2002 from MODIS-derived 8-day composite snow maps with a spatial resolution of about 5 km. A time series of MODIS snow-cover maps of the Sierra Nevada Mountains in California, derived from MODIS-derived daily snow maps with 500-m resolution, is also shown for the winter and spring of 2001.
