CCCma CanESM5.1 model output prepared for CMIP6 ScenarioMIP ssp370

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.ScenarioMIP.CCCma.CanESM5-1.ssp370' 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 CanESM5.1 climate model, released in 2022, includes the following components:
aerosol: interactive, atmos: CanAM5.1 (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.

第六阶段耦合模式比较计划（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集包含所有发布于`CMIP6.ScenarioMIP.CCCma.CanESM5-1.ssp370`的数据集，其完整数据参考语法遵循模板`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。

2022年发布的CanESM5.1气候模式包含以下组分：气溶胶模块支持交互式模拟；大气模块为CanAM5.1（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1 hPa）；大气化学模块采用气溶胶氧化性组分指定方案；陆面过程模块采用CLASS3.6/CTEM1.2方案；陆冰模块采用指定冰盖方案；海洋模块为NEMO3.4.1（ORCA1极坐标网格，原始分辨率1°，赤道20°范围内加密至1/3°；经纬度格点为361×290；垂直分层45层，顶层网格厚度范围0~6.19 m）；海洋生物地球化学模块为加拿大海洋碳模型（Canadian Model of Ocean Carbon，CMOC），搭载包含OMIP规定碳酸盐化学方案的NPZD生态系统；海冰模块为LIM2。

该模式由加拿大环境与气候变化部气候建模与分析中心（Canadian Centre for Climate Modelling and Analysis, Environment and Climate Change Canada，加拿大不列颠哥伦比亚省维多利亚市，邮编V8P 5C2，简称CCCma）以原生名义分辨率运行：气溶胶模块500 km，大气模块500 km，大气化学模块500 km，陆面模块500 km，陆冰模块500 km，海洋模块100 km，海洋生物地球化学模块100 km，海冰模块100 km。

本项目相关说明：本数据集作为国际协调的第六阶段耦合模式比较计划（CMIP6；详见《地球系统模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果，其模拟数据可为解答基础科学问题的气候研究提供支撑，同时为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）的撰稿人员提供研究资源。

第六阶段耦合模式比较计划由世界气候研究计划（World Climate Research Programme，WCRP）下属的耦合建模工作组（Working Group on Coupled Modelling，WGCM）协调推进。该阶段延续了此前由气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导的前序项目，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）及众多相关协作活动完成部署。原始数据存储于分布式数据节点网络并实现部分复制，IPCC所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 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家科研机构及组织的参与。项目官网：https://pcmdi.llnl.gov/CMIP6。
