Annual Precipitation Raster Data of Longpan Reservoir Area (2001-2020)

This dataset is a raster dataset of precipitation in Longpan Reservoir Area from 2001 to 2020 (the reservoir area is based on digital elevation model data and delineated along the ridge line). The original data of this dataset is the "1901-2024 China 1km Resolution Monthly Precipitation Dataset", sourced from the National Earth System Science Data Center (https://www.geodata.cn/). The original dataset is a NetCDF format file, and monthly raster data in TIFF format needs to be created in ArcGIS based on different bands. The annual dataset is obtained by accumulating and summing the raster data of all months within a specific year. This dataset uses the GCS_WGS_1984 coordinate system with a spatial resolution of 1km and units of 0.1mm.

本数据集为2001年至2020年盘龙库区降水栅格数据集（库区范围基于数字高程模型（Digital Elevation Model, DEM）数据沿山脊线划定）。本数据集的原始数据为《1901-2024中国1km分辨率逐月降水数据集》，数据来源为国家地球系统科学数据中心（https://www.geodata.cn/）。原始数据集为网络通用数据格式（NetCDF）文件，需依托ArcGIS软件依据不同波段生成标记图像文件格式（TIFF）的逐月栅格数据。年度降水数据集通过对特定年份内各月的栅格降水数据进行累加求和得到。本数据集采用GCS_WGS_1984坐标系，空间分辨率为1km，数据单位为0.1毫米。
