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

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.historical' 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——本系列数据为国际协调推进的耦合模式比较计划第六阶段（CMIP6；详见《地球科学模式发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果。模拟数据为解答核心科学问题的气候研究提供了关键支撑，同时可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）的作者群体提供研究资源。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）协调统筹。第六阶段延续了此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导的前期项目，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）及众多相关协作项目完成落地实施。原始数据存储于分布式数据节点联合体并进行部分副本备份，IPCC所依赖的绝大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）开展长期归档保存。本项目汇集了全球约120个全球气候模式与45家科研机构及组织的模拟成果。

数据集概述：本数据集包含IPCC AR6第一工作组作者所使用的原始ESGF发布数据集的子集，对应标识为`CMIP6.CMIP.SNU.SAM0-UNICON.historical`，其完整数据引用语法（Data Reference Syntax）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）气候模式于2017年发布，其组成模块包括：气溶胶模块MAM3、大气模块CAM5.3搭配UNICON（分辨率1°；经纬度网格288×192；垂直分层30层；顶层气压约2 hPa）、陆面模块CLM4.0、海洋模块POP2（偏移极点坐标系；经纬度网格320×384；垂直分层60层；表层网格水深0~10 m）、海冰模块CICE4.0。该模式由韩国首尔的首尔国立大学（Seoul National University, SNU）以原生标称分辨率运行：气溶胶、大气、陆面、海洋与海冰模块分辨率均为100 km。
