CCCma CanESM5 model output prepared for CMIP6 DCPP dcppC-forecast-addElChichon

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.DCPP.CCCma.CanESM5.dcppC-forecast-addElChichon' 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，简称CMIP6）数据集：此类数据集涵盖所有以「CMIP6.DCPP.CCCma.CanESM5.dcppC-forecast-addElChichon」标识发布的数据集，其完整数据引用语法遵循模板：`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。

2019年发布的CanESM5气候模式包含以下组成模块：
气溶胶模块：交互式模拟；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，垂直分层49层，顶层气压为1百帕）；大气化学模块：气溶胶前体氧化剂配置；陆面模块：CLASS3.6/CTEM1.2；陆冰模块：冰盖参数化配置；海洋模块：NEMO3.4.1（ORCA1三极网格，原始分辨率1°，赤道20度范围内加密至1/3°，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：加拿大海洋碳模式（Canadian Model of Ocean Carbon，CMOC）；包含采用海洋模式比较计划（Ocean Model Intercomparison Project，简称OMIP）规定的碳酸盐化学配置的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下属的加拿大气候模拟与分析中心（Canadian Centre for Climate Modelling and Analysis，简称CCCma）运行，其运行的标称原生分辨率如下：
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。

项目说明：此类数据集作为国际协调推进的耦合模式比较计划第六阶段（CMIP6，详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出物生成。该模拟数据为解答核心科学问题的气候研究提供支撑，同时亦可作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者群体的参考资源。

CMIP6由耦合模式工作组（Working Group on Coupled Modelling，简称WGCM）协调开展，隶属于世界气候研究计划（World Climate Research Programme，简称WCRP）。第六阶段依托此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，简称PCMDI）主导下完成的多轮计划建设，其实施依赖地球系统网格联盟（Earth System Grid Federation，简称ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，简称CEDA），并配套开展多项相关支撑工作。

原始数据集托管于联邦化的数据节点集群并实现部分镜像备份；IPCC依赖的绝大多数数据目前正由德国气候计算中心（German Climate Computing Center，简称DKRZ）托管的IPCC数据分发中心（IPCC Data Distribution Centre，简称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模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
