IPCC DDC: CCCma CanESM5 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.CCCma.CanESM5.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 CanESM5 climate model, released in 2019, includes the following components: aerosol: interactive, atmos: CanAM5 (T63L49 native atmosphere, T63 Linear Gaussian Grid; 128 x 64 longitude/latitude; 49 levels; top level 1 hPa), atmosChem: specified oxidants for aerosols, land: CLASS3.6/CTEM1.2, landIce: specified ice sheets, ocean: NEMO3.4.1 (ORCA1 tripolar grid, 1 deg with refinement to 1/3 deg within 20 degrees of the equator; 361 x 290 longitude/latitude; 45 vertical levels; top grid cell 0-6.19 m), ocnBgchem: Canadian Model of Ocean Carbon (CMOC); NPZD ecosystem with OMIP prescribed carbonate chemistry, seaIce: LIM2. The model was run by the Canadian Centre for Climate Modelling and Analysis, Environment and Climate Change Canada, Victoria, BC V8P 5C2, Canada (CCCma) in native nominal resolutions: aerosol: 500 km, atmos: 500 km, atmosChem: 500 km, land: 500 km, landIce: 500 km, ocean: 100 km, ocnBgchem: 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开展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。该模拟数据为解答核心科学问题的气候研究提供了基础支撑，同时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）的作者群体提供了核心数据源。CMIP6由耦合模式工作组（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。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）主导完成的多轮耦合模式比较计划，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）及众多相关配套活动完成项目落地。原始数据存储于分布式数据节点联合体中并实现部分副本存储，IPCC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）进行长期归档保存。该项目汇聚了全球约120个全球气候模式及45家左右的科研机构与组织的模拟成果。
