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

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published 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. 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.

耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集包含所有以`CMIP6.HighResMIP.CNRM-CERFACS.CNRM-CM6-1-HR.control-1950`为标识发布的数据集，其完整数据参考语法遵循`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`模板格式。
2017年发布的CNRM-CM6-1-HR气候模式包含以下组成模块：
- 气溶胶模块：采用TACTIC_v2方案计算的逐月强迫场；
- 大气模块：Arpege 6.3模式（采用T359分辨率；高斯缩减格网，总计181724个格点，分布于360个纬度圈：南北纬32.2°之间每个纬度圈包含720个格点，向南北纬89.6°处缩减至每个纬度圈18个格点；共91层模式顶，顶层高度为78.4 km）；
- 大气化学模块：OZL_v2方案；
- 陆面模块：Surfex 8.0c；
- 海洋模块：Nemo 3.6（采用eORCA025网格，三极式布局，主分辨率约1/4度；经纬度格点数为1442×1050；共75层，顶层网格厚度范围为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，CNRM，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，CERFACS，图卢兹31057，法国，合称CNRM-CERFACS）以原生标称分辨率运行，各模块分辨率分别为：气溶胶、大气、大气化学、陆面模块为100 km，海洋与海冰模块为25 km。

项目背景：本数据集作为国际协调开展的耦合模式比较计划第六阶段（CMIP6，详见《地球科学模式发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的一部分生成。该模拟数据可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（Intergovernmental Panel on Climate Change Sixth Assessment Report，IPCC-AR6）作者群体的参考资源。

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。第六阶段依托此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的多阶段工作，其实施依赖地球系统网格联盟（Earth System Grid Federation，ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，CEDA），并配套众多相关协作活动。

原始数据托管于联邦式数据节点集群并进行部分副本存储；IPCC所依赖的多数数据已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。该项目涵盖全球约120个全球气候模式的模拟结果，参与单位约45家。
