MODIS/Terra Snow Cover Monthly L3 Global 0.05Deg CMG, Version 61
This global Level-3 (L3) data set provides monthly mean snow cover extent within 0.05° (approx. 5 km) MODIS Climate Modeling Grid (CMG) cells. This data set is derived from snow cover observations in the 'MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG’ data set (DOI:10.5067/MODIS/MOD10C1.061).
The terms "Version 61" and "Collection 6.1" are used interchangeably in reference to this release of MODIS data.
This is the most recent version of these data.
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.
