2000-2019年中国1km空间分辨率气温栅格数据集

该数据集采用全球日气候历史数据网络（Daily Global Historical Climatology Network-Daily，GHCN-D）和中国气象局国家气象信息中心制作的“中国地面气候资料日值数据集”（其中GHCN-D有345个站点，“中国地面气候资料日值数据集”有753个地面气象观测站），选取日降水和日均温两个要素，对其进行读取、合并、检查、统计、空间插值批处理代码的生成等操作，最后由ANUSPLINE软件插值生成1 km空间分辨率的栅格数据。

This dataset utilizes the Daily Global Historical Climatology Network-Daily (GHCN-D) and the 'Daily Surface Climatic Dataset of China' developed by the National Meteorological Information Center of the China Meteorological Administration. Specifically, GHCN-D includes 345 meteorological stations, whereas the 'Daily Surface Climatic Dataset of China' comprises 753 surface meteorological observation stations. Two core meteorological variables, daily precipitation and daily mean air temperature, are selected for processing. A series of operations including data reading, merging, quality inspection, statistical analysis, and batch code generation for spatial interpolation are conducted on the selected datasets. Finally, the ANUSPLINE software is employed to generate raster data with a spatial resolution of 1 km through interpolation.
