MOHC HadGEM3-GC31-LL model output prepared for CMIP6 CFMIP amip-lwoff

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CFMIP.MOHC.HadGEM3-GC31-LL.amip-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 HadGEM3-GC3.1-N96ORCA1 climate model, released in 2016, includes the following components:
aerosol: UKCA-GLOMAP-mode, atmos: MetUM-HadGEM3-GA7.1 (N96; 192 x 144 longitude/latitude; 85 levels; top level 85 km), land: JULES-HadGEM3-GL7.1, ocean: NEMO-HadGEM3-GO6.0 (eORCA1 tripolar primarily 1 deg with meridional refinement down to 1/3 degree in the tropics; 360 x 330 longitude/latitude; 75 levels; top grid cell 0-1 m), seaIce: CICE-HadGEM3-GSI8 (eORCA1 tripolar primarily 1 deg; 360 x 330 longitude/latitude).
The model was run by the Met Office Hadley Centre, Fitzroy Road, Exeter, Devon, EX1 3PB, UK (MOHC) in native nominal resolutions: aerosol: 250 km, atmos: 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.CFMIP.MOHC.HadGEM3-GC31-LL.amip-lwoff`相关数据集。

于2016年发布的HadGEM3-GC3.1-N96ORCA1气候模式包含以下组成模块：
气溶胶模块：UKCA-GLOMAP-mode；大气模块：MetUM-HadGEM3-GA7.1（分辨率为N96，经纬度网格尺寸为192×144，共85层，顶层高度为85 km）；陆面模块：JULES-HadGEM3-GL7.1；海洋模块：NEMO-HadGEM3-GO6.0（采用eORCA1三极网格，基础分辨率约1°，热带区域经向加密至1/3°，经纬度网格尺寸为360×330，共75层，顶层网格深度范围为0~1 m）；海冰模块：CICE-HadGEM3-GSI8（采用eORCA1三极网格，基础分辨率约1°，经纬度网格尺寸为360×330）。

该模式由位于英国德文郡埃克塞特市菲茨罗伊路的英国气象局哈德利中心（Met Office Hadley Centre，MOHC）以原生标称分辨率运行，各模块分辨率分别为：气溶胶模块250 km，大气模块250 km，陆面模块250 km，海洋模块100 km，海冰模块100 km。

项目说明：本数据集作为国际协调的耦合模型比较计划第六阶段（CMIP6，详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果，其模拟数据可为解答基础气候科学问题提供研究支撑，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）作者的参考资源。

CMIP6由世界气候研究计划（World Climate Research Programme，WCRP）下属的耦合模式工作组（Working Group on Coupled Modelling，WGCM）协调推进。第六阶段继承了此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导完成的前几阶段工作成果，并依托地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关活动完成项目落地。原始数据托管于分布式数据节点联盟并进行部分副本存储，政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）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。

该项目汇聚了全球约120个全球气候模式与45家左右的科研机构及组织。- 项目官网：https://pcmdi.llnl.gov/CMIP6。
