CCCma CanESM5 model output prepared for CMIP6 CFMIP abrupt-2xCO2

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CFMIP.CCCma.CanESM5.abrupt-2xCO2' 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：这些数据包含所有以"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.CFMIP.CCCma.CanESM5.abrupt-2xCO2"相关数据集。

CanESM5气候模型于2019年发布，包含以下组件：
气溶胶（aerosol）：交互式；大气（atmos）：CanAM5（T63L49原生大气，T63线性高斯网格；经纬度128×64；49层；顶层1百帕）；大气化学（atmosChem）：气溶胶特定氧化剂；陆面（land）：CLASS3.6/CTEM1.2；陆冰（landIce）：特定冰盖；海洋（ocean）：NEMO3.4.1（ORCA1三极网格，赤道20度范围内分辨率从1度细化至1/3度；经纬度361×290；45个垂直层；顶层网格单元0-6.19米）；海洋生物地球化学（ocnBgchem）：加拿大海洋碳模型（Canadian Model of Ocean Carbon，CMOC）；采用OMIP规定碳酸盐化学的NPZD生态系统；海冰（seaIce）：LIM2。

该模型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（Canadian Centre for Climate Modelling and Analysis，CCCma，位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：500千米；大气：500千米；大气化学：500千米；陆面：500千米；陆冰：500千米；海洋：100千米；海洋生物地球化学：100千米；海冰：100千米。

项目背景：这些数据是国际协调的耦合模式比较计划第六阶段（CMIP6）的一部分（另见《地球科学模型开发》（GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html）。模拟数据为旨在解答基础科学问题的气候研究提供了基础，并作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）作者的资源。

CMIP6是由耦合模式工作组（Working Group on Coupled Modelling，WGCM）协调、作为世界气候研究计划（World Climate Research Programme，WCRP）一部分的项目。第六阶段基于气候模型诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下执行的前几阶段，并依赖地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）以及众多相关活动来实施。原始数据托管于联合数据节点集合并部分复制，IPCC所依赖的大部分数据正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）存档以长期保存。

该项目包含来自全球约120个全球气候模型和45个机构及组织的模拟结果。- 项目网站：https://pcmdi.llnl.gov/CMIP6。
