IPCC DDC: CNRM-CERFACS CNRM-ESM2-1 model output prepared for CMIP6 CMIP piControl

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.CMIP.CNRM-CERFACS.CNRM-ESM2-1.piControl' 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.

项目：耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）数据集——本数据集为国际协作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。其模拟数据可为解答核心科学问题的气候研究提供支撑，同时可作为政府间气候变化专门委员会第六次评估报告（Intergovernmental Panel on Climate Change Sixth Assessment Report, IPCC-AR6）作者团队的参考资源。
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）统筹协调。本第六阶段工作依托于此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导开展的多轮前期研究，并通过地球系统网格联盟（Earth System Grid Federation, ESGF）、环境数据分析中心（Centre for Environmental Data Analysis, CEDA）及众多相关配套项目顺利推进实施。原始数据由分布式数据节点集群托管并实现部分副本存储，IPCC所依赖的绝大多数数据已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）完成长期归档保存。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。
数据集概况：本数据集包含IPCC AR6第一工作组作者所使用的原始数据集子集，该子集源自ESGF平台发布的`CMIP6.CMIP.CNRM-CERFACS.CNRM-ESM2-1.piControl`数据集，其数据参考语法（Data Reference Syntax）遵循模板格式：`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-ESM2-1气候模式包含以下组分：气溶胶模块采用TACTIC_v2，大气模块采用Arpege 6.3（分辨率为T127，采用高斯缩减网格，总计24572个网格点，其中南北纬30°区间内的每个纬度圈包含256个网格点，至南北纬88.9°时缩减至每个纬度圈20个网格点；共设置91层大气，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（采用eORCA1三极式网格，基础分辨率约1°；经度/纬度网格尺寸为362×294；共75层海洋，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, CNRM，图卢兹31057）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）联合开发运营（合称CNRM-CERFACS），其原生标称分辨率如下：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。
