IPCC DDC: NERC HadGEM3-GC31-HH model output prepared for CMIP6 HighResMIP

Project: Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets - 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. Summary: These data include the subset used by IPCC AR6 WGI authors of the datasets originally published in ESGF for 'CMIP6.HighResMIP.NERC.HadGEM3-GC31-HH' 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-N512ORCA12 climate model, released in 2016, includes the following components: aerosol: UKCA-GLOMAP-mode, atmos: MetUM-HadGEM3-GA7.1 (N512; 1024 x 768 longitude/latitude; 85 levels; top level 85 km), land: JULES-HadGEM3-GL7.1, ocean: NEMO-HadGEM3-GO6.0 (eORCA12 tripolar primarily 1/12 deg; 4320 x 3604 longitude/latitude; 75 levels; top grid cell 0-1 m), seaIce: CICE-HadGEM3-GSI8 (eORCA12 tripolar primarily 1/12 deg; 4320 x 3604 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: 50 km, atmos: 50 km, land: 50 km, ocean: 10 km, seaIce: 10 km.

项目：耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集——本数据集为国际协调开展的耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）的产出成果，详见《地球科学模型开发》（Geoscientific Model Development，GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html。
该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（Intergovernmental Panel on Climate Change，IPCC）第六次评估报告（IPCC-AR6）作者群体的核心数据资源。
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）。第六阶段的工作基于此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的多轮次耦合模式比较计划，其实施依托地球系统网格联盟（Earth System Grid Federation，ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，CEDA），并联动多项相关配套工作。
原始数据存储于分布式数据节点集群中并实现部分副本存储，政府间气候变化专门委员会（IPCC）所依赖的绝大多数数据目前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。该项目涵盖了全球约120个全球气候模式的模拟结果，参与单位共计约45家科研机构与组织。
数据集概况：本数据集包含政府间气候变化专门委员会第六次评估报告第一工作组（IPCC AR6 WGI）作者所使用的子集数据，该子集原始发布于地球系统网格联盟（ESGF），对应标识为"CMIP6.HighResMIP.NERC.HadGEM3-GC31-HH"，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-N512ORCA12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（N512分辨率；经纬度网格为1024×768；共85层，大气顶层海拔85km）；陆面模块：JULES-HadGEM3-GL7.1；海洋模块：NEMO-HadGEM3-GO6.0（采用eORCA12三极网格，核心分辨率约1/12度；经纬度网格为4320×3604；共75层，顶层网格水深范围0~1m）；海冰模块：CICE-HadGEM3-GSI8（采用eORCA12三极网格，核心分辨率约1/12度；经纬度网格为4320×3604）。
该模式由英国自然环境研究委员会（Natural Environment Research Council，NERC，位于英国牛津哈威尔的STFC-RAL，邮编OX11 0QX）以固有标称分辨率运行：气溶胶模块50km、大气模块50km、陆面模块50km、海洋模块10km、海冰模块10km。
