IPCC DDC: CNRM-CERFACS CNRM-ESM2-1 model output prepared for CMIP6 ScenarioMIP ssp534-over

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.ScenarioMIP.CNRM-CERFACS.CNRM-ESM2-1.ssp534-over' 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——这些数据是国际协调开展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。该模拟数据为旨在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（Intergovernmental Panel on Climate Change, IPCC）第六次评估报告（IPCC-AR6）的撰稿人提供数据资源。
CMIP6由耦合建模工作组（Working Group on Coupled Modelling, WGCM）作为世界气候研究计划（World Climate Research Programme, WCRP）的一部分协调推进。第六阶段继承了此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导的前期阶段成果，并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）及众多相关配套活动完成落地实施。
原始数据托管于联邦式数据节点集群并实现部分副本存储，IPCC所依赖的多数数据正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）进行长期保存归档。该项目包含来自全球约120个全球气候模式以及45家科研机构与组织的模拟试验数据。
摘要：本数据集包含IPCC AR6第一工作组撰稿人所使用的原始数据集子集，该子集最初发布于ESGF平台，对应试验标识为'CMIP6.ScenarioMIP.CNRM-CERFACS.CNRM-ESM2-1.ssp534-over'，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-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；高斯缩减网格，总计24572个网格点，在128条纬度圈上分布——北纬30°至南纬30°区间每条纬度圈包含256个网格点，在88.9°N与88.9°S处缩减至每条纬度圈20个网格点；共91层垂直结构，顶层高度为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网格，三级极点配置，基础分辨率约1°；经度/纬度网格尺寸为362×294；共75层垂直结构，顶层网格深度区间为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。
