Global Seasonal-Snow Classification, Version 1

This data set consists of global, seasonal snow classifications—e.g., tundra, boreal forest, maritime, ephemeral, prairie, montane forest, and ice—determined from air temperature, precipitation, and wind speed climatologies. Data are available on global, North America, and Eurasia latitude-longitude grids at four resolutions: 10 arcsec (~300 m), 30 arcsec (~1 km), 2.5 arcmin (~5 km), and 0.5° (~50 km).
