NERC HadGEM3-GC31-LL model output prepared for CMIP6 FAFMIP

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.FAFMIP.NERC.HadGEM3-GC31-LL' 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 Natural Environment Research Council, STFC-RAL, Harwell, Oxford, OX11 0QX, UK (NERC) 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.FAFMIP.NERC.HadGEM3-GC31-LL'为标识发布的数据集，其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'。

2016年发布的HadGEM3-GC3.1-N96ORCA1气候模式包含以下组成部分：
气溶胶模块：UKCA-GLOMAP-mode；大气模块：MetUM-HadGEM3-GA7.1（N96格网；经纬度格点为192×144；共85层，顶层高度为85公里）；陆面模块：JULES-HadGEM3-GL7.1；海洋模块：NEMO-HadGEM3-GO6.0（eORCA1极坐标格网，基础分辨率为1°，热带地区经向加密至1/3°；经纬度格点为360×330；共75层，顶层网格深度范围为0~1米）；海冰模块：CICE-HadGEM3-GSI8（eORCA1极坐标格网，基础分辨率为1°；经纬度格点为360×330）。

该模式由英国牛津郡哈威尔的自然环境研究委员会（Natural Environment Research Council，NERC）下属STFC-RAL完成运行，其标称原生分辨率如下：气溶胶模块：250公里，大气模块：250公里，陆面模块：250公里，海洋模块：100公里，海冰模块：100公里。

项目背景：本数据集作为国际协调推进的耦合模式比较计划第六阶段（CMIP6；详见《地球模式开发》（Geoscientific Model Development，GMD）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坚实基础，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）撰稿人的参考资源。

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）。第六阶段依托气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导的前期阶段成果，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）及众多相关协作活动完成项目实施。原始数据托管于联邦化数据节点集群并进行部分副本存储，IPCC所依赖的绝大多数数据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。

该项目涵盖全球约120个全球气候模式的模拟试验，以及来自全球约45家机构与组织的参与贡献。——项目官网：https://pcmdi.llnl.gov/CMIP6。
