CCCma CanESM5 model output prepared for CMIP6 CDRMIP

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

耦合模式比较计划第六阶段（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`为模板的完整数据参考语法发布的`CMIP6.CDRMIP.CCCma.CanESM5`相关数据集。

2019年发布的CanESM5气候模式包含以下组成模块：气溶胶模块：采用交互式处理方案；大气模块：CanAM5（T63L49原生大气模式，采用T63线性高斯网格，经纬度格点为128×64，垂直分层49层，顶层气压为1百帕）；大气化学模块：针对气溶胶设定氧化剂配置；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1°，赤道20度范围内加密至1/3°分辨率，经纬度格点数为361×290，垂直分层45层，表层网格水深范围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），搭载带有OMIP规定碳酸盐化学配置的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气候模拟与分析中心（Canadian Centre for Climate Modelling and Analysis, CCCma）运营，其办公地点位于加拿大不列颠哥伦比亚省维多利亚市（邮编V8P 5C2），各模块采用原生标称分辨率：气溶胶模块：500千米，大气模块：500千米，大气化学模块：500千米，陆面模块：500千米，陆冰模块：500千米，海洋模块：100千米，海洋生物地球化学模块：100千米，海冰模块：100千米。

本数据集作为国际协作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）的产出成果生成。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）下属的耦合模式工作组（Working Group on Coupled Modelling, WGCM）协调推进。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）主导开展的多轮模式比较工作，其实施依托地球系统网格联合会（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。原始数据存储于分布式联合数据节点集群并进行部分复制，IPCC依赖的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。

本项目汇聚了全球约120个全球气候模式及45家科研机构与组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
