CESM1CAM5 global coupled climate model ensemble simulations 1850-1979. All forcing and regional aerosol experiments (SST, precipitation, AOD, MOC)

Monthly sea surface temperature (SST), aerosol optical depth (AOD), precipitation (PRECIP), and Meridional Overturning Circulation (MOC) data from historical experiments (1850-1979) with the global coupled model CESM1-CAM5.<br>The data are from three experiments with 8 members each:<br>1) a CMIP5 standard all-forcing experiments (BTAL, in the publication ALL) <br><br>2) an experiment with all forcings except anthropogenic aerosol emissions from North America (BTALnNA, in the publication noNA, 8 members) and<br><br>3) an experiment with all forcings except anthropogenic aerosol emissions from Europe (BTALnEU, in the publication NoEU, 8 members) are kept at pre-industrial levels.<br>For more details on the model configuration, details of the modified emissions, and the definitions of the North American and European region, respectively, see reference:<br>Undorf, S., M.

本数据集涵盖全球耦合模式CESM1-CAM5在1850-1979年历史试验中产出的逐月数据，包括海表温度（Sea Surface Temperature, SST）、气溶胶光学厚度（Aerosol Optical Depth, AOD）、降水量（Precipitation, PRECIP）以及经向翻转环流（Meridional Overturning Circulation, MOC）。
该数据分为3组试验，每组均包含8个集合成员：
1) 耦合模式比较计划第五阶段（Coupled Model Intercomparison Project Phase 5, CMIP5）标准全强迫试验（BTAL，对应发表文献ALL）

2) 去除北美地区人为气溶胶排放强迫的全强迫试验（BTALnNA，对应发表文献noNA，共8个集合成员）

3) 去除欧洲地区人为气溶胶排放强迫的全强迫试验（BTALnEU，对应发表文献NoEU，共8个集合成员，该试验中相关人为气溶胶排放维持工业前水平）。
如需了解模式配置、修改后的排放细节，以及北美、欧洲区域的具体定义，请参阅以下参考文献：
