四川省公里格网降尺度降水数据（2000-2014）

本数据集包含了2000-2014年15年间的四川省TRMM降尺度降水数据，分别由2000-2014年逐月降水量组成，空间分辨率1km，时间分辨率为月和年。采取Albers双纬线圆锥投影，数据类型主要是栅格数据，ArcGIS tiff格式，数据更新频度为12个月。主要应用领域为水土保持、水文变化、林业生产、生态环境建设等研究领域，本数据集以期为相关研究人员提供公里格网降尺度降水数据，顺利开展科研活动

This dataset encompasses TRMM downscaled precipitation data for Sichuan Province spanning the 15-year interval from 2000 to 2014. It consists of monthly precipitation totals covering each month within this period, with a spatial resolution of 1 km and temporal resolutions of both monthly and annual scales. The data employs the Albers double-standard parallel conic projection, is primarily raster-based, and stored in ArcGIS TIFF format, with an update frequency of once every 12 months. Its main application fields include research on soil and water conservation, hydrological variations, forestry production, ecological environment construction, and other related research areas. This dataset is intended to provide kilometer-grid downscaled precipitation data for relevant researchers to facilitate their smooth implementation of scientific research activities.
