CCCma CanESM5 model output prepared for CMIP6 DAMIP ssp245-GHG

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.DAMIP.CCCma.CanESM5.ssp245-GHG' 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：本数据集包含所有遵循`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`模板的完整数据引用语法的`CMIP6.DAMIP.CCCma.CanESM5.ssp245-GHG`相关已发布数据集。

CanESM5气候模式于2019年发布，其组成模块如下：
气溶胶模块：交互式处理；大气模块：CanAM5（原生大气配置为T63L49，采用T63线性高斯网格，经纬度格点为128×64，共49个垂直层，顶层气压为1 hPa）；大气化学模块：气溶胶指定氧化剂方案；陆面模块：CLASS3.6/CTEM1.2；陆冰模块：指定冰盖方案；海洋模块：NEMO3.4.1（ORCA1三极网格，1°分辨率，赤道20°范围内加密至1/3°分辨率，经纬度格点为361×290，共45个垂直层，顶层网格单元水深范围为0~6.19 m）；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）；搭载带有海洋模式比较计划（Ocean Model Intercomparison Project, OMIP）指定碳酸盐化学方案的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维多利亚加拿大气候模拟与分析中心（Canadian Centre for Climate Modelling and Analysis, Environment and Climate Change Canada, Victoria, BC V8P 5C2, Canada，简称CCCma）以原生标称分辨率运行：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。

本项目相关数据作为国际协同推进的耦合模式比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》专刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果生成。该模拟数据为解答基础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）作者的参考资源。

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）主导开展的多阶段工作，并依托地球系统网格联盟（Earth System Grid Federation, ESGF）与环境数据分析中心（Centre for Environmental Data Analysis, CEDA）及众多相关配套活动完成项目落地。原始数据存储于分布式数据节点集合中并实现部分副本共享，IPCC所依赖的多数数据集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个全球气候模式与近45家科研机构与组织的研究成果。- 项目官网：https://pcmdi.llnl.gov/CMIP6。
