CMIP5 simulations of the Max Planck Institute for Meteorology (MPI-M) based on the MPI-ESM-LR model: The esmHistorical experiment, served by ESGF

Project: IPCC Assessment Report 5 and Coupled Model Intercomparison Project data sets - These data belong to two projects: 1) to the Assessment Report No 5 of the International Panel on Climate Change (IPCC-AR5) and 2) to the Coupled Model Intercomparison Project No 5 (CMIP5). CMIP5 is executed by the Program for Climate Model Diagnosis and Intercomparison (PCMDI) on behalf of the World Climate Research Programme (WCRP). Most of the data is replicated between the three data nodes at the World Data Centre for Climate (WDCC), the British Atmospheric Data Centre (BADC), and the PCMDI. The project embraces the simulations with about 30 climate models of about 20 institutes worldwide. Summary: "esmHistorical" is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5). CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the AR5 as well as others that extend beyond the AR5. 5.2 esmHistorical (5.2 ESM historical): Historical simulation (1850 to 2005) as in experiment 3.2_historical but emissions-forced (with atmospheric CO2 determined by the model itself) Experiment design: https://pcmdi.llnl.gov/mips/cmip5/experiment_design.html List of output variables: https://pcmdi.llnl.gov/mips/cmip5/datadescription.html Output: time series per variable in model grid spatial resolution in netCDF format Earth System model and the simulation information: CIM repository Entry name/title of data are specified according to the Data Reference Syntax (https://pcmdi.llnl.gov/mips/cmip5/docs/cmip5_data_reference_syntax.pdf) as activity/product/institute/model/experiment/frequency/modeling realm/MIP table/ensemble member/version number/variable name/CMOR filename.nc.

项目：政府间气候变化专门委员会第五次评估报告与耦合模式比较计划数据集——本数据集包含两个项目范畴：1）国际气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）第五次评估报告（IPCC-AR5）相关项目；2）第五次耦合模式比较计划（Coupled Model Intercomparison Project Phase 5, CMIP5）。CMIP5由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）代表世界气候研究计划（World Climate Research Programme, WCRP）牵头执行。全球约20家科研机构的近30个气候模式所生成的模拟试验数据，大部分会在世界气候数据中心（World Data Centre for Climate, WDCC）、英国大气数据中心（British Atmospheric Data Centre, BADC）以及PCMDI的三个数据节点间进行副本备份。

摘要：“esmHistorical”是第五次耦合模式比较计划（CMIP5）的一项试验（https://pcmdi.llnl.gov/mips/cmip5）。CMIP5旨在为未来五年的协同气候变化试验提供标准化框架，因此既涵盖用于IPCC-AR5评估的模拟试验，也包含超出AR5评估范围的其他模拟试验。

5.2 esmHistorical（5.2 ESM Historical）：即与3.2_historical试验一致的历史模拟试验，时间跨度为1850年至2005年，但其采用排放强迫机制（大气CO₂浓度由模式自身计算确定）。试验设计详情请见：https://pcmdi.llnl.gov/mips/cmip5/experiment_design.html
输出变量列表请见：https://pcmdi.llnl.gov/mips/cmip5/datadescription.html

输出结果：以netCDF格式存储的、匹配模式网格空间分辨率的各变量时间序列。
