The Global SnowPack is a set of snow cover parameters made available on a global scale. It is based on daily, medium resolution remote sensing datasets (MOD10A1 and MYD10A1) provided by the National Snow and Ice Data Center (NSIDC). The data was reprocessed to clear data gaps caused by clouds and polar darkness and now informs about snow cover duration as well as early and late season snow cover duration for each hydrological year (September 1st of a calendar year to August 31st of the subsequent year) since 2000.
