CMCC CMCC-CM2-VHR4 model output prepared for CMIP6 HighResMIP highres-future

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.HighResMIP.CMCC.CMCC-CM2-VHR4.highres-future' 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-VHR4 climate model, released in 2017, includes the following components:
aerosol: prescribed MACv2-SP, atmos: CAM4 (1/4deg; 1152 x 768 longitude/latitude; 26 levels; top at ~2 hPa), land: CLM4.5 (SP mode), ocean: NEMO3.6 (ORCA0.25 1/4 deg from the Equator degrading at the poles; 1442 x 1051 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: 25 km, atmos: 25 km, land: 25 km, ocean: 25 km, seaIce: 25 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.

耦合模型比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有针对`CMIP6.HighResMIP.CMCC.CMCC-CM2-VHR4.highres-future`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`。

CMCC-CM2-VHR4气候模式于2017年发布，包含以下组成模块：气溶胶模块采用预设MACv2-SP方案；大气模块为CAM4（分辨率1/4度，经纬度网格为1152×768，共26层，顶层气压约2 hPa）；陆面模块为CLM4.5（SP模式）；海洋模块为NEMO3.6（ORCA0.25，赤道区域分辨率为1/4度，极地区域分辨率退化，经纬度网格为1442×1051，共50个垂直层，顶层网格单元深度范围为0~1 m）；海冰模块为CICE4.0。

该模式由意大利莱切73100的地中海气候变化基金会（Fondazione Centro Euro-Mediterraneo sui Cambiamenti Climatici，CMCC）以原生标称分辨率运行，各模块分辨率均为25 km。

本数据集作为国际协调推进的耦合模型比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果生成。该模拟数据可为解答基础科学问题的气候研究提供支撑，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）作者的数据资源。

CMIP6由世界气候研究计划（WCRP）下属的耦合建模工作组（WGCM）协调实施。第六阶段继承了此前由气候模型诊断与比较计划（PCMDI）主导的多阶段项目成果，依托地球系统网格联合会（ESGF）、环境数据分析中心（CEDA）及众多相关协作活动完成落地。原始数据托管于联邦化数据节点集群并进行部分副本存储，IPCC所依赖的多数数据将由德国气候计算中心（DKRZ）托管的IPCC数据分发中心（IPCC DDC）进行长期归档保存。

该项目汇集了全球约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.
