Description

This global Level-3 (L3) data set provides the percentage of snow-covered land and cloud-covered land observed daily, within 0.05° (approx. 5 km) MODIS Climate Modeling Grid (CMG) cells. Percentages are computed from snow cover observations in the 'MODIS/Aqua Snow Cover Daily L3 Global 500m Grid' data set (DOI:10.5067/MODIS/MYD10A1.061).

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

Version Description

1. The low visible reflectance screen for snow cover using bands 2 and 4 was lowered from 0.10 to 0.07. 2. Cloud mask algorithm flags are set for 'probably cloudy' and 'probably clear' sky conditions in the algorithm flags QA data set.
