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.

本数据集包含全球耦合模式CESM1-CAM5在1850-1979年的历史试验数据，涵盖逐月海表温度（Sea Surface Temperature, SST）、气溶胶光学厚度（Aerosol Optical Depth, AOD）、降水量（Precipitation, PRECIP）及经向翻转环流（Meridional Overturning Circulation, MOC）。
该数据集来自3组试验，每组均包含8个成员：
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（对应文献中ALL组的BTAL试验）
2) 排除北美人为气溶胶排放的全强迫试验（对应文献中noNA组的BTALnNA试验，共8个成员）
3) 排除欧洲人为气溶胶排放的全强迫试验（对应文献中NoEU组的BTALnEU试验，共8个成员），该试验中相关人为气溶胶排放维持在工业化前水平。
关于模式配置、修正后的排放细节以及北美、欧洲区域的定义，请参阅以下参考文献：
