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).本数据集包含基于气温、降水量和风速气候学数据确定的全球季节性积雪分类——例如苔原、北方森林、海洋性、短暂性、草原、山地森林及冰雪类型。数据在全球、北美洲及欧亚大陆的经纬度网格上提供，包含四种分辨率：10角秒（约300米）、30角秒（约1千米）、2.5角分（约5千米）及0.5度（约50千米）。
