CNRM-CERFACS CNRM-CM6-1 model output prepared for CMIP6 CFMIP aqua-control-lwoff

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CFMIP.CNRM-CERFACS.CNRM-CM6-1.aqua-control-lwoff' 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.

耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有以`CMIP6.CFMIP.CNRM-CERFACS.CNRM-CM6-1.aqua-control-lwoff`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`。

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方案计算的逐月强迫场；大气模块为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条纬圈：南北纬30°区间内每条纬圈包含256个网格点，向南北纬88.9°逐渐缩减至每条纬圈20个网格点；共91层，顶层高度为78.4 km）；大气化学模块为OZL_v2；陆面模块为Surfax 8.0c；海洋模块为Nemo 3.6（采用eORCA1网格，以极地方向为基准的1°分辨率；经纬度网格尺寸为362×294；共75层，顶层网格深度范围为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（CNRM，法国图卢兹31057）与欧洲科学计算高级研究与培训中心（CERFACS，法国图卢兹31057）联合运行（合称CNRM-CERFACS），其原生标称分辨率如下：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、海冰模块100 km。

本数据集作为国际协调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，同时亦可作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者群体的参考资源。

CMIP6由耦合模式工作组（WGCM）作为世界气候研究计划（WCRP）的一部分协调推进。第六阶段继承了此前在气候模式诊断与比较计划（PCMDI）主导下完成的前期阶段成果，并依托地球系统网格联盟（ESGF）与环境数据分析中心（CEDA）及众多相关配套活动完成项目实施。原始数据托管于联邦式数据节点集群并实现部分镜像，IPCC所依赖的绝大多数数据将交由德国气候计算中心（DKRZ）运营的IPCC数据分发中心（IPCC DDC）进行长期归档保存。

该项目涵盖全球约120个全球气候模式与45家机构及组织的模拟试验。项目官方网站：https://pcmdi.llnl.gov/CMIP6。
