Delivery of Suomi National Polar-orbiting Partnership (Suomi NPP) satellite data products will cease on November 1, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.Suomi NPP data announcement
Description
This global Level-3 (L3) data set provides a daily composite of snow cover and albedo derived from the 'MODIS/Aqua Snow Cover 5-Min L2 Swath 500m' data set (DOI:10.5067/MODIS/MYD10_L2.061). Each data granule is a 10°x10° tile projected to a 500 m sinusoidal grid.
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.
Citation is critically important for dataset documentation and discovery. This dataset is openly shared, without restriction, in accordance with the EOSDIS Data Use and Citation Guidance.
