CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 DAMIP hist-aer

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.DAMIP.CNRM-CERFACS.CNRM-CM6-1.hist-aer' 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：本数据集涵盖所有发布于`CMIP6.DAMIP.CNRM-CERFACS.CNRM-CM6-1.hist-aer`的数据集，完整数据引用语法遵循模板`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。

2017年发布的CNRM-CM6-1气候模式包含以下组分：气溶胶模块采用TACTIC_v2方案计算的逐月强迫场；大气模块为Arpege 6.3（T127格型；高斯缩减格网，总计24572个格点，在128条纬度圈上分布：南北纬30°区间内每条纬度圈包含256个格点，向南北纬88.9°处逐步缩减至每条纬度圈仅20个格点；共计91层垂直结构，顶层高度达78.4 km）；大气化学模块为OZL_v2；陆面模块为Surfex 8.0c；海洋模块为Nemo 3.6（采用eORCA1网格，以极区为原点的近似1°分辨率；经度方向362个格点、纬度方向294个格点；共计75层垂直结构，顶层格距范围为0~1 m）；海冰模块为Gelato 6.1。

该模式由法国国家气象研究中心（Centre National de Recherches Meteorologiques，法国图卢兹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，法国图卢兹31057）联合开发（简称CNRM-CERFACS），采用原生标称分辨率：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，海冰模块100 km。

本数据集作为国际协同推进的耦合模型比较计划第六阶段（CMIP6；详见《地球科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果，其模拟数据为解答核心科学问题的气候研究提供支撑，同时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）的作者提供研究资源。

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）的组成部分统筹协调。第六阶段延续了此前由气候模型诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导的前期阶段工作，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），并联动多项相关活动完成项目落地。原始数据存储于分布式数据节点集群并实现部分副本，IPCC所依赖的多数数据集将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 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家科研机构及组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
