CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 PMIP lig127k

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.PMIP.CNRM-CERFACS.CNRM-CM6-1.lig127k' 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 climate model, released in 2017, includes the following components: aerosol: prescribed monthly fields computed by TACTIC_v2 scheme, 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: OZL_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), 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, 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.

耦合模型比对项目第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有针对"CMIP6.PMIP.CNRM-CERFACS.CNRM-CM6-1.lig127k"发布的数据集，其数据参考语法严格遵循模板"mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version"。

CNRM-CM6-1气候模型于2017年发布，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（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°区间内每条纬度圈包含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91个垂直层，顶层高度达78.4 km）；大气化学模块：OZL_v2；陆面模块：Surfax 8.0c；海洋模块：Nemo 3.6（采用eORCA1网格，主要为1°极地方格网格；经纬度网格尺寸为362×294；共75个垂直层，顶层网格深度范围为0~1 m）；海冰模块：Gelato 6.1。该模型由法国国家气象研究中心（Centre National de Recherches Meteorologiques，图卢兹31057，法国）与欧洲计算科学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）以原生名义分辨率运行：气溶胶模块分辨率为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，海冰模块100 km。

项目背景：本数据集作为国际协调开展的耦合模型比对项目第六阶段（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）作者的研究资源。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）的组成部分协调推进。第六阶段继承了此前由气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导的前期项目成果，依托地球系统网格联合会（Earth System Grid Federation，ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，CEDA），并结合众多相关实施活动完成项目落地。原始数据托管于联邦式数据节点集群并实现部分复制，IPCC所依赖的多数数据将由德国气候计算中心（Deutsches Klimarechenzentrum，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。该项目汇集了全球约120个全球气候模型与约45家科研机构及组织的模拟成果。
