本数据集是利用MODIS数据为基础，改进地形影响的NDSI比值算法获取积雪面积，并进行时空数据插值，最后与AMSR-E微波雪深产品进行多源数据融合而得到。
\n\n该数据集采用经纬度（Geographic）投影方式，大地基准面为WGS84，空间分辨率0.005°，提供2008-2010年逐日的青藏高原无云覆盖积雪面积图。数据集按年份存放，共由3个文件夹组成，从2008到2010。每个文件夹里包含当年的逐日积雪覆盖分类结果，为tif文件，命名规则为：YYYY.tif，其中YYYY代表年（2008-2010），代表日（001~365/366）。可直接用ARCGIS或者ENVI打开。

\nThis dataset adopts a longitude and latitude (Geographic) projection method, with a geodetic reference plane of WGS84 and a spatial resolution of 0.005 °. It provides a daily map of the cloudless snow cover area of the Qinghai Tibet Plateau from 2008 to 2010. The dataset is stored by year and consists of three folders, from 2008 to 2010. Each folder contains the daily snow cover classification results of the current year, which is a tif file. The Naming convention is YYYY. tif, where YYYY represents the year (2008-2010) andrepresents the day (001~365/366). It can be opened directly using ARCGIS or ENVI
