CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 HighResMIP hist-1950

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.HighResMIP.CNRM-CERFACS.CNRM-CM6-1.hist-1950' with the full Data Reference Syntax following the template 'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'. The CNRM-CM6-1 climate model, released in 2017, includes the following components: aerosol: prescribed monthly fields computed by TACTIC_v2 scheme, atmos: Arpege 6.3 (T127; Gaussian Reduced with 24572 grid points in total distributed over 128 latitude circles (with 256 grid points per latitude circle between 30degN and 30degS reducing to 20 grid points per latitude circle at 88.9degN and 88.9degS); 91 levels; top level 78.4 km), atmosChem: OZL_v2, land: Surfex 8.0c, ocean: Nemo 3.6 (eORCA1, tripolar primarily 1deg; 362 x 294 longitude/latitude; 75 levels; top grid cell 0-1 m), seaIce: Gelato 6.1. The model was run by the CNRM (Centre National de Recherches Meteorologiques, Toulouse 31057, France), CERFACS (Centre Europeen de Recherche et de Formation Avancee en Calcul Scientifique, Toulouse 31057, France) (CNRM-CERFACS) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, atmosChem: 250 km, land: 250 km, ocean: 100 km, seaIce: 100 km. Project: These data have been generated as part of the internationally-coordinated Coupled Model Intercomparison Project Phase 6 (CMIP6; see also GMD Special Issue: http://www.geosci-model-dev.net/special_issue590.html). The simulation data provides a basis for climate research designed to answer fundamental science questions and serves as resource for authors of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6). CMIP6 is a project coordinated by the Working Group on Coupled Modelling (WGCM) as part of the World Climate Research Programme (WCRP). Phase 6 builds on previous phases executed under the leadership of the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and relies on the Earth System Grid Federation (ESGF) and the Centre for Environmental Data Analysis (CEDA) along with numerous related activities for implementation. The original data is hosted and partially replicated on a federated collection of data nodes, and most of the data relied on by the IPCC is being archived for long-term preservation at the IPCC Data Distribution Centre (IPCC DDC) hosted by the German Climate Computing Center (DKRZ). The project includes simulations from about 120 global climate models and around 45 institutions and organizations worldwide. - Project website: https://pcmdi.llnl.gov/CMIP6.

耦合模型比对项目第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有以CMIP6.HighResMIP.CNRM-CERFACS.CNRM-CM6-1.hist-1950为标识发布的数据集，且完整遵循格式为mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version的数据引用语法（Data Reference Syntax）。
CNRM-CM6-1气候模式于2017年发布，其组成模块如下：气溶胶模块采用TACTIC_v2方案计算的指定月均场；大气模块采用Arpege 6.3模式，谱截断为T127，采用高斯缩减网格，总计24572个网格点，分布于128条纬度圈（南北纬30°区间内每条纬度圈包含256个网格点，向南北纬88.9°处逐渐缩减至每条纬度圈20个网格点）；共设91层，顶层高度为78.4 km；大气化学模块为OZL_v2；陆面模块为Surfex 8.0c；海洋模块为Nemo 3.6（采用eORCA1网格，以主要为1°分辨率的三极网格为基础，经纬度维度为362×294，共75层，顶层网格水深范围为0~1 m）；海冰模块为Gelato 6.1。
该模式由法国国家气象研究中心（Centre National de Recherches Meteorologiques，图卢兹 31057，法国）与欧洲科学计算高级研究与培训中心（Centre Europeen de Recherche et de Formation Avancee en Calcul Scientifique，图卢兹 31057，法国，合称CNRM-CERFACS）以原标称分辨率运行：气溶胶模块分辨率为250 km，大气模块为250 km，大气化学模块为250 km，陆面模块为250 km，海洋模块为100 km，海冰模块为100 km。
本数据集作为国际协调开展的耦合模型比对项目第六阶段（CMIP6，详见《地球科学模式发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果生成。该模拟数据为解答基础科学问题的气候研究提供支撑，同时作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者群体的核心研究资源。CMIP6由世界气候研究计划（WCRP）下属的耦合建模工作组（WGCM）协调推进。第六阶段依托此前由气候模型诊断与比对计划（PCMDI）主导的前期项目，借助地球系统网格联盟（ESGF）与环境数据分析中心（CEDA）及众多相关协作活动完成实施。原始数据存储于分布式数据节点集群并进行部分副本备份，IPCC所依赖的多数数据将由德国气候计算中心（DKRZ）托管的IPCC数据分发中心（IPCC DDC）进行长期归档保存。该项目汇聚了全球约120个全球气候模式与45家左右的科研机构与组织。项目官网：https://pcmdi.llnl.gov/CMIP6。
