NOAA GFDL GFDL-ESM2M, esmHistorical experiment output for CMIP5 AR5, 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（Intergovernmental Panel on Climate Change Assessment Report 5，IPCC-AR5）与第五次耦合模式比较计划（Coupled Model Intercomparison Project Phase 5，CMIP5）数据集——本数据集隶属于两个项目：1）政府间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（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）牵头实施。全球约20家科研机构的近30个气候模式所产生的模拟试验数据，大部分均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）及PCMDI的三个数据节点间完成冗余备份。
概述：“esmHistorical”是CMIP5（第五次耦合模式比较计划）的一项试验（详情参见：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，其涵盖了用于IPCC-AR5评估的模拟试验，以及其他超出AR5评估范围的模拟试验。
5.2 esmHistorical（历史地球系统模式模拟）：该试验为1850年至2005年的历史模拟，与3.2节的“historical”试验逻辑一致，但以排放为强迫条件（大气CO₂浓度由模式自身计算确定）。试验设计规范详见：https://pcmdi.llnl.gov/mips/cmip5/experiment_design.html
输出变量清单详见：https://pcmdi.llnl.gov/mips/cmip5/datadescription.html
输出数据为采用netCDF格式存储的、匹配模式网格空间分辨率的逐变量时间序列数据集。
