CNRM-CERFACS CNRM-ESM2-1 model output prepared for CMIP6 RFMIP

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.RFMIP.CNRM-CERFACS.CNRM-ESM2-1' 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-ESM2-1 climate model, released in 2017, includes the following components: aerosol: TACTIC_v2, 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: REPROBUS-C_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), ocnBgchem: Pisces 2.s, 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, ocnBgchem: 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.

耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有遵循`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`完整数据参考语法（Data Reference Syntax）模板发布的`CMIP6.RFMIP.CNRM-CERFACS.CNRM-ESM2-1`相关数据集。CNRM-ESM2-1气候模式于2017年正式发布，其组成模块包括：气溶胶模块采用TACTIC_v2，大气模块采用Arpege 6.3（T127分辨率；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°范围内每条纬度圈包含256个网格点，向南北纬88.9°处逐步缩减至每条纬度圈20个网格点；共计91层垂直结构，顶层高度达78.4 km），大气化学模块采用REPROBUS-C_v2，陆面模块采用Surfex 8.0c，海洋模块采用Nemo 3.6（eORCA1配置，极地方向主要为1°分辨率；经纬度网格尺寸为362×294；共计75层垂直结构，顶层网格水深范围为0~1 m），海洋生物地球化学模块采用Pisces 2.s，海冰模块采用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，二者合称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，海洋生物地球化学模块100 km，海冰模块100 km。本数据集作为国际协调推进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）的产出成果生成。该模拟数据可为解答基础科学问题的气候研究提供核心支撑，同时可作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者群体的参考资源。CMIP6由世界气候研究计划（WCRP）下属的耦合模式工作组（WGCM）协调统筹。第六阶段继承了此前由气候模式诊断与比较计划（PCMDI）主导开展的前序阶段工作，并依托地球系统网格联合会（ESGF）、环境数据分析中心（CEDA）及众多相关配套活动完成项目落地实施。原始数据存储于联邦数据节点集群并实现部分副本分发，IPCC所依赖的绝大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家左右的科研机构及组织的模拟成果。项目官网：https://pcmdi.llnl.gov/CMIP6。
