CMIP5 simulations of the Max Planck Institute for Meteorology (MPI-M) based on the MPI-ESM-MR model: The decadal1975 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: 'decadal1975' 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. 1.1 decadal1975 (1.1 10-year hindcast/prediction initialized in year 1975) - Version 1: The atmospheric composition (and other conditions) should be prescribed as in the historical run (expt. 3.2) and the RCP4.5 scenario (expt. 4.1) of the long-term suite of experiments. Ocean initial conditions should be in some way representative of the observed anomalies or full fields for the start date. Land, sea-ice and atmosphere initial conditions are left to the discretion of each group.

项目：IPCC第五次评估报告与耦合模式比较计划数据集——本数据集包含两项计划的相关数据：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）；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种气候模式所生成的模拟数据，大部分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的三个数据节点间实现冗余存储。该项目涵盖了来自全球约20家机构的近30个气候模式的模拟试验。
摘要：「decadal1975」是CMIP5（第五次耦合模式比较计划，详见https://pcmdi.llnl.gov/mips/cmip5）的一项试验。CMIP5旨在为未来五年的协同气候变化试验提供框架，其包含的模拟内容既包括用于IPCC-AR5评估的试验，也涵盖了超出AR5评估范围的其他试验。
1.1 decadal1975（1.1 1975年启动的十年期后报/预报试验）——版本1：大气成分（及其他模拟条件）应参照长期试验套件中的历史运行试验（试验3.2）与RCP4.5情景模拟试验（试验4.1）的设置进行规定。海洋初始条件需在一定程度上代表启动日期的观测异常值或完整场数据。陆面、海冰与大气的初始条件则由各建模团队自行确定。试验设计方案详见：https://pcmdi.llnl.gov/mips/cmip5/experiment_design.html；输出变量列表详见：https://pcmdi.llnl.gov/mips/cmip5/datadescription.html。
输出：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。
