Data details

Name Snow Cover Extent (SCE) 1km Northern Hemisphere
Note Snow cover extent is mapped daily in near-real time for the northern hemisphere with a geometric resolution of 0.01deg x 0.01deg per pixel, based on optical satellite data from Level 1B calibrated radiances of Suomi-NPP VIIRS (Visible Infrared Imaging Radiometer Suite). Main elements are: Snow classification is applied on top-of-atmosphere reflectance of visible and mid-infrared bands, and brightness temperatures of thermal infrared bands to get the daily fractional snow cover extent per pixel. A canopy correction is applied to provide snow cover extent on the ground in forested areas, and clouds, water bodies, polar night and missing data pixels are flagged.

Snow Coverage Fully Snow-cover can compromise the quality of InSAR results by increasing the noise of time series. The SCE 1km product forthe Northern Hemisphere provides needed information about the extent of seasonal and permanent snow cover in higher latitudes and mountaneous regions. This helps to filter out images with extensive snow cover allowing for a reliable InSAR coverage with reduced noise for production. July 20, 2022, 8:38 a.m. Oct. 5, 2022, 9 a.m.
