MOD10A2061 Snow Cover 8-Day L3 Global 500m

MOD10A2 is a snow cover data set from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite. The data set consists of 1200 km by 1200 km tiles of 500 m resolution data gridded in a sinusoidal map projection. The data set reports the maximum snow cover extent during an eight-day period. The snow cover algorithm identifies snow-covered land and snow-covered ice on inland water. The algorithm uses a Normalized Difference Snow Index (NDSI) and other criteria tests. The eight-day compositing period was chosen because that is the exact ground track repeat period of the Terra and Aqua platforms.
