CCCma CanESM5 model output prepared for CMIP6 CMIP amip

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.CCCma.CanESM5.amip' 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.

Project: 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. - Project website: https://pcmdi.llnl.gov/CMIP6.

耦合模型比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有以“mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version”为完整数据参考语法（Data Reference Syntax）模板发布的“CMIP6.CMIP.CCCma.CanESM5.amip”相关数据集。

于2019年发布的CanESM5气候模式包含以下组成模块：
气溶胶模块：采用交互式参数化方案；大气模块：CanAM5（T63L49原生大气模式，采用T63线性高斯网格；经纬度分辨率为128×64；共49层大气，顶层大气顶气压为1百帕）；大气化学模块：指定气溶胶氧化剂参数；陆面模块：CLASS3.6/CTEM1.2；陆冰模块：采用指定冰盖参数；海洋模块：NEMO3.4.1（ORCA1三极网格，基础分辨率为1°，赤道20°范围内加密至1/3°；经纬度网格为361×290；共45个垂直层；顶层网格单元水深范围为0~6.19米）；海洋生物地球化学模块：加拿大海洋碳循环模式（Canadian Model of Ocean Carbon，CMOC）；搭载OMIP指定碳酸盐化学参数的NPZD生态系统；海冰模块：LIM2。

该模式由加拿大环境与气候变化部下属的加拿大气候模拟与分析中心（CCCma）于加拿大不列颠哥伦比亚省维多利亚市（邮编V8P 5C2）以原生标称分辨率运行：气溶胶模块500公里，大气模块500公里，大气化学模块500公里，陆面模块500公里，陆冰模块500公里，海洋模块100公里，海洋生物地球化学模块100公里，海冰模块100公里。

本数据集作为国际协调推进的耦合模型比较计划第六阶段（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，其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（IPCC-AR6）的撰稿作者提供参考资源。

CMIP6由世界气候研究计划（World Climate Research Programme，WCRP）下属的耦合模拟工作组（Working Group on Coupled Modelling，WGCM）统筹协调。第六阶段延续了此前由气候模型诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的多阶段对比研究，并依托地球系统网格联合会（Earth System Grid Federation，ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关协作项目完成落地。原始数据存储于联邦数据节点集群并进行部分副本存储，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个全球气候模式与45家机构组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
