CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 DAMIP

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.DAMIP.CNRM-CERFACS.CNRM-CM6-1' 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：本数据集包含所有针对`CMIP6.DAMIP.CNRM-CERFACS.CNRM-CM6-1`发布的数据集，其数据引用语法严格遵循模板`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。2017年发布的CNRM-CM6-1气候模式包含以下组成部分：气溶胶模块：采用TACTIC_v2方案计算得到的逐月指定场；大气模块：Arpege 6.3（T127截断，采用缩减高斯网格，总计24572个网格点，分布于128条纬圈，其中南北纬30°间每条纬圈包含256个网格点，向南北纬88.9°处逐渐缩减至每条纬圈20个网格点；垂直分层共91层，顶层高度为78.4 km）；大气化学模块：OZL_v2；陆面模块：Surfax 8.0c；海洋模块：Nemo 3.6（采用eORCA1三极网格，标称分辨率约1°，经纬度网格尺寸为362×294，垂直分层共75层，顶层网格深度范围为0~1 m）；海冰模块：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）基于原生标称分辨率运行，各模块分辨率分别为：气溶胶模块250 km，大气模块250 km，大气化学模块250 km，陆面模块250 km，海洋模块100 km，海冰模块100 km。项目概况：本数据集作为国际协作的耦合模型比对项目第六阶段（CMIP6；详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果之一。该模拟数据为解答核心科学问题的气候研究提供了基础支撑，同时也可为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）的撰稿人提供数据支持。CMIP6由世界气候研究计划（World Climate Research Programme，WCRP）下属的耦合模式工作组（Working Group on Coupled Modelling，WGCM）牵头协调。第六阶段依托此前由气候模式诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的多轮项目经验，其实施依赖地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）以及众多相关协作活动。原始数据托管于分布式数据节点集群并进行部分副本存储，IPCC所依赖的绝大多数数据将由德国气候计算中心（German Climate Computing Center，DKRZ）运营的IPCC数据分发中心（IPCC Data Distribution Centre，IPCC DDC）进行长期归档保存。该项目涵盖了全球约120个全球气候模式以及约45家科研机构与组织的模拟成果。项目官网：https://pcmdi.llnl.gov/CMIP6。
