资源简介：
全球2000年以来每年冰雪覆盖百分比产品，提供像元一年内所有观测中有冰雪覆盖的比率。产品采用MODIS时间序列观测，通过反射率对比，逐像元确立分割拐点，识别冰雪观测，统计获得冰雪覆盖百分比。产品覆盖全球，空间分辨率为500m，时间分辨率为年。
Global annual snow and ice cover percentage products since the year 2000. This product quantifies the ratio of snow/ice-covered observations to all annual observations for each pixel. Built upon MODIS time-series observations, the product identifies snow and ice-covered observations by deriving segmentation inflection points on a per-pixel basis through reflectance comparison, and derives the final snow and ice cover percentage via statistical calculation. The product features full global coverage, with a spatial resolution of 500 meters and an annual temporal resolution.
