CMCC CMCC-CM2-SR5 model output prepared for CMIP6 CMIP piControl

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.CMCC.CMCC-CM2-SR5.piControl' 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 CMCC-CM2-SR5 climate model, released in 2016, includes the following components:
aerosol: MAM3, atmos: CAM5.3 (1deg; 288 x 192 longitude/latitude; 30 levels; top at ~2 hPa), land: CLM4.5 (BGC mode), ocean: NEMO3.6 (ORCA1 tripolar primarly 1 deg lat/lon with meridional refinement down to 1/3 degree in the tropics; 362 x 292 longitude/latitude; 50 vertical levels; top grid cell 0-1 m), seaIce: CICE4.0.
The model was run by the Fondazione Centro Euro-Mediterraneo sui Cambiamenti Climatici, Lecce 73100, Italy (CMCC) in native nominal resolutions: aerosol: 100 km, atmos: 100 km, land: 100 km, ocean: 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（Data Reference Syntax）、针对`CMIP6.CMIP.CMCC.CMCC-CM2-SR5.piControl`发布的数据集。

于2016年发布的CMCC-CM2-SR5气候模式包含以下组成模块：
气溶胶模块：MAM3；大气模块：CAM5.3（分辨率1°，经纬度网格为288×192，共30层，顶层气压约2 hPa）；陆面模块：CLM4.5（生物地球化学模式，即BGC mode）；海洋模块：NEMO3.6（ORCA1三极网格，主要经纬度分辨率为1°，热带区域经向加密至1/3°，经纬度网格为362×292，共50个垂直层，顶层网格深度范围为0~1 m）；海冰模块：CICE4.0。

该模式由意大利莱切（邮编73100）的欧洲地中海气候变化中心基金会（Fondazione Centro Euro-Mediterraneo sui Cambiamenti Climatici，CMCC）运行，其标称原始分辨率为：气溶胶模块100 km，大气模块100 km，陆面模块100 km，海洋模块100 km，海冰模块100 km。

项目背景：本数据集为国际协同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）的产出成果。该模拟数据为解答基础科学问题的气候研究提供了支撑，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（Sixth Assessment Report of the Intergovernmental Panel on Climate Change，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）协调开展。第六阶段继承了此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的前期阶段工作，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实施。原始数据托管于分布式数据节点集群并进行部分复制，而IPCC所依赖的大部分数据目前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）进行长期归档保存。

该项目汇聚了全球约120个全球气候模式与约45家科研机构及组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
