CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 PAMIP pa-futArcSIC-ext

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.PAMIP.CNRM-CERFACS.CNRM-CM6-1.pa-futArcSIC-ext' 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：本数据集包含所有以`CMIP6.PAMIP.CNRM-CERFACS.CNRM-CM6-1.pa-futArcSIC-ext`为标识发布的数据集，其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-CM6-1气候模式包含以下组成模块：
气溶胶模块：采用TACTIC_v2方案计算得到的逐月气溶胶强迫场；
大气模块：Arpege 6.3（T127格型；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°处缩减至每条纬圈20个格点）；共91层，模式顶高78.4 km）；
大气化学模块：OZL_v2；
陆地模块：Surfex 8.0c；
海洋模块：Nemo 3.6（eORCA1三极格网，主分辨率为1°；经纬度格点数为362×294；共75层，顶层网格单元深度范围为0~1 m）；
海冰模块：Gelato 6.1。

该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）以固有标称分辨率运行：气溶胶模块分辨率为250 km，大气模块为250 km，大气化学模块为250 km，陆地模块为250 km，海洋模块为100 km，海冰模块为100 km。

本数据集作为国际协调的耦合模型比对项目第六阶段（CMIP6；详见《地球系统模型发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果之一，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）作者群体的研究资源。

CMIP6由耦合模式工作组（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。第六阶段依托此前在气候模式诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的前期项目，借助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）及众多相关配套活动完成实施。原始数据托管并部分复现于数据节点联邦集群中，IPCC所依赖的多数数据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 Data Distribution Centre，IPCC DDC）进行长期保存归档。

该项目涵盖全球约120个全球气候模式的模拟实验与约45家科研机构及组织的参与。——项目官网：https://pcmdi.llnl.gov/CMIP6。
