黑河流域中上游100m×100m空间分辨率气候平均年降水量（1967-2008）

基于高精度的DEM数据，统计分析了黑河流域中上游地区的气候平均年降水量与地理地形因子的关系，得到100m空间分辨率的黑河流域中上游1967-2008年逐年气候平均年降水量。
坐标系统为等经纬度投影，空间范围为黑河流域。数据采用txt文本形式给出，分别给出空间网格点所对应的经度，纬度和降水量。经纬度单位为°，降水量单位为mm。数据类型为单精度浮点型，无效值为-9。

Based on high-precision Digital Elevation Model (DEM) data, this study statistically analyzed the relationship between climatological mean annual precipitation and geographical and topographical factors in the middle and upper reaches of the Heihe River Basin, and derived the 100 m spatial resolution annual climatological mean precipitation data for each year from 1967 to 2008 in this region. The coordinate system adopts the equirectangular projection, and the spatial scope covers the Heihe River Basin. The data is provided in TXT format, which separately records the longitude, latitude and precipitation values corresponding to each spatial grid point. The units of longitude and latitude are degrees (°), and the unit of precipitation is millimeters (mm). The data type is single-precision floating-point, and the no-data value is -9.
