IPCC DDC: CNRM-CERFACS CNRM-CM6-1-HR model output prepared for CMIP6 HighResMIP control-1950

Project: Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets - 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. Summary: These data include the subset used by IPCC AR6 WGI authors of the datasets originally published in ESGF for 'CMIP6.HighResMIP.CNRM-CERFACS.CNRM-CM6-1-HR.control-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-HR climate model, released in 2017, includes the following components: aerosol: prescribed monthly fields computed by TACTIC_v2 scheme, atmos: Arpege 6.3 (T359; Gaussian Reduced with 181724 grid points in total distributed over 360 latitude circles (with 720 grid points per latitude circle between 32.2degN and 32.2degS reducing to 18 grid points per latitude circle at 89.6degN and 89.6degS); 91 levels; top level 78.4 km), atmosChem: OZL_v2, land: Surfex 8.0c, ocean: Nemo 3.6 (eORCA025, tripolar primarily 1/4deg; 1442 x 1050 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: 100 km, atmos: 100 km, atmosChem: 100 km, land: 100 km, ocean: 25 km, seaIce: 25 km.

项目：耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）数据集——这些数据是国际协调推进的耦合模式比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果。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，同时可作为政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）第六次评估报告（IPCC-AR6）作者的研究资源。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）协调实施。第六阶段延续了此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导的多阶段项目成果，依托地球系统网格联盟（Earth System Grid Federation, ESGF）、环境数据分析中心（Centre for Environmental Data Analysis, CEDA）及众多相关协作活动完成落地。原始数据存储于分布式数据节点集群并实现部分复制，IPCC依赖的绝大多数数据将由德国气候计算中心（German Climate Computing Center, DKRZ）托管的IPCC数据分发中心（IPCC Data Distribution Centre, IPCC DDC）进行长期归档保存。该项目汇聚了全球约120个全球气候模式与45家科研机构及组织的模拟成果。摘要：本数据集包含IPCC-AR6第一工作组（Working Group I, WGI）作者所使用的子集数据，原始数据集以`CMIP6.HighResMIP.CNRM-CERFACS.CNRM-CM6-1-HR.control-1950`为名发布于ESGF平台，其完整数据参考语法遵循模板：`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。于2017年发布的CNRM-CM6-1-HR气候模式包含以下组成模块：气溶胶：由TACTIC_v2方案计算得到的指定式逐月场；大气：Arpege 6.3（T359格型；高斯缩减格点，总计181724个网格点，分布于360条纬度圈：南北纬32.2°区间内每条纬度圈包含720个网格点，向南北纬89.6°处逐步缩减至每条纬度圈18个网格点；共91层，顶层高度78.4 km）；大气化学：OZL_v2；陆面：Surfex 8.0c；海洋：Nemo 3.6（eORCA025，三极式网格，标称分辨率约1/4°；经纬度网格尺寸为1442×1050；共75层，顶层网格单元水深范围0~1 m）；海冰：Gelato 6.1。该模式由法国图卢兹的法国国家气象研究中心（Centre National de Recherches Meteorologiques, CNRM）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, CERFACS，合称CNRM-CERFACS）以原生标称分辨率运行，各模块分辨率如下：气溶胶：100 km，大气：100 km，大气化学：100 km，陆面：100 km，海洋：25 km，海冰：25 km。
