MODIS Snow Cover over North America

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. In this animation, a time series of global snow cover from MODIS-derived 8-day composite snow maps with a spatial resolution of about 5 km shows the dynamic behavior of the advance and retreat of continental snow cover over North America during the winter of 2001-02.
