CCCma CanESM5 model output prepared for CMIP6 VolMIP volc-long-eq

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.VolMIP.CCCma.CanESM5.volc-long-eq' 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.

耦合模型比对项目第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有遵循模板`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`的完整数据参考语法、以`CMIP6.VolMIP.CCCma.CanESM5.volc-long-eq`为题发布的相关数据集。

2019年发布的CanESM5气候模式包含以下组成模块：气溶胶模块支持交互式处理；大气模块采用CanAM5（T63L49原生大气模式，搭载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 hPa）；大气化学模块用于为气溶胶设定氧化剂；陆面模块采用CLASS3.6/CTEM1.2；陆冰模块采用指定冰盖参数方案；海洋模块采用NEMO3.4.1（ORCA1三极网格，基础分辨率为1°，赤道20°范围内加密至1/3°分辨率，经纬度网格尺寸为361×290，垂直分层45层，顶层网格水深范围为0~6.19 m）；海洋生物地球化学模块搭载加拿大海洋碳循环模型（Canadian Model of Ocean Carbon，CMOC），包含配备OMIP规定碳酸盐化学过程的NPZD生态系统；海冰模块采用LIM2。

该模式由加拿大环境与气候变化部加拿大气候模拟与分析中心（Canadian Centre for Climate Modelling and Analysis，CCCma）运行，运行地址为不列颠哥伦比亚省维多利亚市，邮编V8P 5C2，加拿大，各模块采用原生标称分辨率：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。

本数据集作为国际协调的耦合模型比对项目第六阶段（CMIP6；详见《地球系统模型发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果生成。这套模拟数据可为解答核心科学问题的气候研究提供基础支撑，同时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由耦合建模工作组（Working Group on Coupled Modelling，WGCM）作为世界气候研究计划（World Climate Research Programme，WCRP）的组成部分协调推进。第六阶段承接此前在气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的前期项目，依托地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关活动完成项目落地。原始数据托管并部分复制于联邦化数据节点集群，IPCC所依赖的绝大多数数据将由德国气候计算中心（German Climate Computing Center，DKRZ）运营的IPCC数据分发中心（IPCC Data Distribution Centre，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家科研机构及组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
