中国1km分辨率多情景多模式逐月平均气温数据集（2021-2100）

数据集为中国多情景多模式逐月平均气温数据，空间分辨率为0.0083333°(约1km)，时间为2021年1月-2100年12月。数据为NETCDF格式。数据是根据IPCC耦合模式比较计划第六阶段（CMIP6）发布的全球>100 km气候模式数据集以及WorldClim发布的全球高分辨率气候数据集，通过Delta空间降尺度方案在中国地区降尺度生成。数据采用IPCC最新发布的SSP情景(SSP119、SSP245、SSP585),每个情景包含三个GCMs（EC-Earth3、GFDL-ESM4、MRI-ESM2-0）气候数据，数据集包含的地理空间范围是中国主要陆地，不含南海岛礁等区域。单位为0.1℃。文件命名是GCM_SSP_tmp-30s-序号.nc，30s即0.0083333°，序号从1-40，序号1表示2021.1-2022.12，依次表示年份；以EC-Earth3_ssp119_tmp-30s-1.nc文件为例，表示SSP119情景下EC-Earth3气候模的1km分辨率2021.1-2022.12逐月均温数据，含24个图层。欲更深入的理解数据请参阅文献引用方式下的数据作者已发表的论文。

This dataset presents monthly mean air temperature data across mainland China under multiple Shared Socioeconomic Pathways (SSP) scenarios and three General Circulation Models (GCMs), with a spatial resolution of 0.0083333° (approximately 1 km) and a temporal span from January 2021 to December 2100. All data is stored in NETCDF format.
The dataset was generated through Delta spatial downscaling over China, leveraging two reference datasets: the global climate model outputs with a resolution greater than 100 km released under the Coupled Model Intercomparison Project Phase 6 (CMIP6) of the Intergovernmental Panel on Climate Change (IPCC), and the global high-resolution climate datasets published by WorldClim.
It utilizes the latest IPCC-released SSP scenarios: SSP119, SSP245, and SSP585. Each scenario incorporates climate data from three GCMs: EC-Earth3, GFDL-ESM4, and MRI-ESM2-0. The spatial coverage includes the main terrestrial areas of China, excluding regions such as the South China Sea islands and reefs. The unit of the temperature data is 0.1°C.
The file naming convention follows the pattern: GCM_SSP_tmp-30s-[serial_number].nc, where "30s" corresponds to 0.0083333°. Serial numbers range from 1 to 40, with serial number 1 representing the period January 2021 to December 2022, and each subsequent serial number corresponding to the next consecutive two-year period. For example, the file EC-Earth3_SSP119_tmp-30s-1.nc contains 1 km resolution monthly mean air temperature data for January 2021 to December 2022 under the SSP119 scenario using the EC-Earth3 climate model, comprising 24 layers in total.
