IPCC DDC: SNU SAM0-UNICON model output prepared for CMIP6 CMIP piControl

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.CMIP.SNU.SAM0-UNICON.piControl' 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 SAM0-UNICON (SNU Atmosphere Model version 0 with Unified Convection Scheme) climate model, released in 2017, includes the following components: aerosol: MAM3, atmos: CAM5.3 with UNICON (1deg; 288 x 192 longitude/latitude; 30 levels; top level ~2 hPa), land: CLM4.0, ocean: POP2 (Displaced Pole; 320 x 384 longitude/latitude; 60 levels; top grid cell 0-10 m), seaIce: CICE4.0. The model was run by the Seoul National University, Seoul 08826, Republic of Korea (SNU) in native nominal resolutions: aerosol: 100 km, atmos: 100 km, land: 100 km, ocean: 100 km, seaIce: 100 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推进的耦合模式比较计划第六阶段（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第六次评估报告（IPCC-AR6）作者群体的核心研究资源。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。第六阶段依托此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导开展的多轮前期建设工作，其落地实施依赖地球系统网格联盟（Earth System Grid Federation, ESGF）与环境数据分析中心（Centre for Environmental Data Analysis, CEDA），并配套多项相关支撑工作。原始数据托管于联邦化数据节点集群，并实现部分副本存储；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）运维的IPCC数据分发中心（IPCC Data Distribution Centre, IPCC DDC）开展长期归档保存工作。本项目涵盖全球约120个全球气候模式的模拟结果，参与单位覆盖全球约45家科研机构与组织。 数据集概况：本数据集包含IPCC AR6第一工作组（Working Group I, WGI）作者所使用的子集数据，其原始数据于ESGF平台发布，对应标识为`CMIP6.CMIP.SNU.SAM0-UNICON.piControl`，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`。SAM0-UNICON（统一对流方案首尔国立大学大气模式0版，SNU Atmosphere Model version 0 with Unified Convection Scheme）气候模式于2017年发布，其组成模块如下：气溶胶模块采用MAM3方案，大气模块为搭载UNICON的CAM5.3（水平分辨率1°；经纬度网格288×192；垂直分层30层；顶层气压约2百帕），陆面模块为CLM4.0，海洋模块为POP2（偏移极坐标；经纬度网格320×384；垂直分层60层；表层网格深度0-10米），海冰模块为CICE4.0。该模式由大韩民国首尔特别市08826号的首尔国立大学（Seoul National University, SNU）以原生标称分辨率开展模拟运行：气溶胶模块分辨率100公里，大气模块100公里，陆面模块100公里，海洋模块100公里，海冰模块100公里。
