1901-2024年中国1km分辨率逐月平均气温数据集

该数据集为中国逐月平均气温数据，空间分辨率为0.0083333°(约1km)，时间为1901.1-2024.12。数据是据CRU发布全球0.5°气候数据以及WorldClim发布的全球高分辨率气候数据，通过Delta空间降尺度方案在中国地区降尺度生成。并用496个独立气象观测点数据进行验证，验证结果可信。气温单位为0.1℃。数据集地理空间范围是中国主要陆地（不含南海岛礁等区域）。为便于存储，数据均为int16型存于nc(NETCDF)文件中，nc数据可用ArcMAP软件打开制图; 并可用Matlab软件进行提取处理。数据作者彭守璋副研究员在《Earth System Science Data》以论文形式发布了1 km monthly temperature and precipitation dataset for China from 1901 to 2017数据。论文链接https://doi.org/10.5194/essd-11-1931-2019。

This dataset is a monthly mean air temperature dataset for mainland China, with a spatial resolution of 0.0083333° (approximately 1 km), spanning the period from January 1901 to December 2024. It was generated via the Delta spatial downscaling scheme using the global 0.5° climate data released by CRU and the global high-resolution climate data released by WorldClim, downscaled over mainland China. The dataset was validated against observations from 496 independent meteorological stations, and the validation results confirm its reliability. The unit of air temperature in this dataset is 0.1℃. The spatial coverage of the dataset is mainland China, excluding regions such as the South China Sea islands and reefs. For convenient storage, all data are stored as int16 type in NETCDF (nc) files. The nc data can be opened and used for mapping with ArcMAP software, and can also be extracted and processed using Matlab. Associate Researcher Peng Shouzhang, the author of this dataset, published a paper titled "1 km monthly temperature and precipitation dataset for China from 1901 to 2017" in the journal *Earth System Science Data*.
