Description

This global Level-3 (L3) data set provides monthly average snow cover within 0.05° (approx. 5 km) MODIS Climate Modeling Grid (CMG) cells. Monthly averages are computed from daily snow cover observations in the MODIS/Aqua Snow Cover Daily L3 Global 0.05Deg CMG (https://doi.org/10.5067/MODIS/MYD10CM.061) data set.

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.
