MODIS/Aqua Snow Cover 8-Day L3 Global 500m SIN Grid V061

This global Level-3 (L3) data set provides the maximum snow cover extent (SNE) observed over an eight-day period within 10° x 10° MODIS sinusoidal grid tiles. Tiles are generated by compositing 500 m observations from the 'MODIS/Aqua Snow Cover Daily L3 Global 500m Grid' data set (DOI:10.5067/MODIS/MYD10A1.061). A bit flag index is used to track the eight-day snow/no-snow chronology for each 500 m cell.

The terms "Version 61" and "Collection 6.1" are used interchangeably in reference to this release of MODIS data.
