IPCC DDC: AWI AWI-CM 1.1 LR 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.AWI.AWI-CM-1-1-LR' 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 AWI-CM 1.1 LR climate model, released in 2018, includes the following components: atmos: ECHAM6.3.04p1 (T63L47 native atmosphere T63 gaussian grid; 192 x 96 longitude/latitude; 47 levels; top level 80 km), land: JSBACH 3.20, ocean: FESOM 1.4 (unstructured grid in the horizontal with 126859 wet nodes; 46 levels; top grid cell 0-5 m), seaIce: FESOM 1.4. The model was run by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Am Handelshafen 12, 27570 Bremerhaven, Germany (AWI) in native nominal resolutions: atmos: 250 km, land: 250 km, ocean: 50 km, seaIce: 50 km.

项目：耦合模型比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）数据集——本数据集作为国际协同开展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）的成果产出。该模拟数据为解答核心科学问题的气候研究提供支撑，同时可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）的撰写作者提供参考资源。CMIP6由耦合建模工作组（Working Group on Coupled Modelling, WGCM）作为世界气候研究计划（World Climate Research Programme, WCRP）的组成部分统筹协调推进。第六阶段依托此前由气候模型诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导开展的前期阶段建设而来，并通过地球系统网格联盟（Earth System Grid Federation, ESGF）、环境数据分析中心（Centre for Environmental Data Analysis, CEDA）及众多配套活动完成项目落地。原始数据托管于联邦式数据节点集群并实现部分副本存储，IPCC所依赖的多数数据将交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。本项目涵盖全球约120个全球气候模型与近45家科研机构及组织产出的模拟数据。概述：本数据集包含IPCC AR6第一工作组（WGI）作者所使用的原始数据集子集，该数据集最初发布于ESGF平台，对应标识为'CMIP6.HighResMIP.AWI.AWI-CM-1-1-LR'，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'。发布于2018年的AWI-CM 1.1 LR气候模型包含以下组成模块：大气模块：ECHAM6.3.04p1（采用T63L47原生大气T63高斯网格；经纬度格点为192×96；共47层，大气顶高度达80 km）；陆面模块：JSBACH 3.20；海洋模块：FESOM 1.4（水平方向采用非结构化网格，包含126859个湿节点；共46层；表层网格单元水深范围0~5 m）；海冰模块：FESOM 1.4。该模型由德国阿尔弗雷德·魏格纳研究所、亥姆霍兹极地与海洋研究中心（Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, AWI）运行，其驻地为德国不来梅哈芬市Am Handelshafen 12号，邮编27570，模型采用原生标称分辨率：大气模块250 km，陆面模块250 km，海洋模块50 km，海冰模块50 km。
