CNRM-CERFACS CNRM-ESM2-1 model output prepared for CMIP6 CMIP for experiment piControl-spinup

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.CNRM-CERFACS.CNRM-ESM2-1.piControl-spinup' 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：本数据集包含所有遵循`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`完整数据引用语法模板发布的`CMIP6.CMIP.CNRM-CERFACS.CNRM-ESM2-1.piControl-spinup`相关数据集。

于2017年发布的CNRM-ESM2-1气候模式包含以下组成模块：气溶胶模块：TACTIC_v2；大气模块：Arpege 6.3（分辨率采用T127高斯缩减格网，总计24572个格点，分布于128条纬圈：南北纬30°间每条纬圈含256个格点，向南北纬88.9°处逐步缩减至每条纬圈20个格点；共计91层垂直层次，顶层高度为78.4 km）；大气化学模块：REPROBUS-C_v2；陆面模块：Surfex 8.0c；海洋模块：Nemo 3.6（采用eORCA1网格，以三极式为主，水平分辨率约1°；经纬度格点数为362×294；共计75层垂直层次，顶层网格深度范围为0~1 m）；海洋生物地球化学模块：Pisces 2.s；海冰模块：Gelato 6.1。

本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）（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。

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《地球科学模型开发》（Geoscientific Model Development，简称GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果之一。该模拟数据可为解答核心科学问题的气候研究提供支撑，同时作为政府间气候变化专门委员会第六次评估报告（Sixth Assessment Report of the Intergovernmental Panel on Climate Change，IPCC-AR6）作者团队的核心数据源。

CMIP6由耦合模式工作组（Working Group on Coupled Modelling，WGCM）协调开展，隶属于世界气候研究计划（World Climate Research Programme，WCRP）。第六阶段依托此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的多轮计划建设，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完成落地实施。

原始数据存储于分布式数据节点集群并实现部分副本同步，IPCC所依赖的绝大多数数据目前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）进行长期归档保存。该项目共纳入全球约120个全球气候模式的模拟结果，参与单位共计约45家科研机构与组织。
