1901-2024年中国1km分辨率逐月最低气温数据集

该数据集为中国逐月最低气温数据，空间分辨率为0.0083333°(约1km)，时间为1901.1-20232.12。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 provides monthly minimum temperature data for China, with a spatial resolution of 0.0083333° (approximately 1 km), spanning from January 1901 to December 2023. It was generated through the Delta spatial downscaling scheme, using the global 0.5° climatic data released by the Climatic Research Unit (CRU) and the global high-resolution climate data from WorldClim as source inputs, and applying downscaling over mainland China. The dataset was validated using observations from 496 independent meteorological stations, and the validation results confirm its reliability. The unit of temperature is 0.1°C. The spatial scope of the dataset covers major terrestrial areas of China, excluding regions such as the South China Sea islands and reefs. For efficient storage, all data are stored as int16 type in NETCDF (nc) files. The nc-format data can be opened and used for mapping with ArcMAP software, and can be extracted and processed using Matlab. The corresponding peer-reviewed publication, authored by Associate Researcher Peng Shouzhang, was published in *Earth System Science Data* with the title "1 km monthly temperature and precipitation dataset for China from 1901 to 2017".
