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

This dataset is the annual mean temperature raster dataset of the Longpan Reservoir Area from 2001 to 2020 (the scope of the reservoir area is delineated along the ridge line based on digital elevation model data).The original data of this dataset is the "Monthly Mean Temperature Dataset of China (1901-2024) with 1 km Resolution", which is sourced from the National Earth System Science Data Center (https://www.geodata.cn/). The original dataset is in NetCDF format; it needs to be converted into monthly raster data in TIFF format by creating layers from different bands in ArcGIS. The annual dataset is obtained by averaging the raster data of all months within a specific year. This dataset adopts the GCS_WGS_1984 coordinate system, with a spatial resolution of 1 km and a unit of °C.

本数据集为2001年至2020年龙盘水库库区年平均温度栅格数据集（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《中国1km分辨率逐月平均温度数据集（1901-2024）》，数据来源于国家地球系统科学数据中心（https://www.geodata.cn/）。原始数据集采用NetCDF格式，需通过ArcGIS软件从不同波段创建图层，将其转换为TIFF格式的逐月栅格数据。年尺度数据集通过对特定年份内所有月份的栅格数据取平均计算得到。本数据集采用GCS_WGS_1984坐标系，空间分辨率为1km，温度单位为°C。
