CMCC CMCC-ESM2 model output prepared for CMIP6 ScenarioMIP ssp585

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.ScenarioMIP.CMCC.CMCC-ESM2.ssp585' 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-ESM2 climate model, released in 2017, 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), ocnBgchem: BFM5.2, 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, 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`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`完整数据参考语法模板发布的`CMIP6.ScenarioMIP.CMCC.CMCC-ESM2.ssp585`相关数据集。

CMCC-ESM2气候模型于2017年发布，其组成模块如下：气溶胶模块采用MAM3方案，大气模块采用CAM5.3（分辨率1°，经纬度网格尺寸288×192，垂直分层30层，顶层气压约2 hPa），陆面模块采用CLM4.5（生物地球化学模式），海洋模块采用NEMO3.6（ORCA1三极网格，主分辨率约1°，热带区域经向加密至1/3°，经纬度网格尺寸362×292，垂直分层50层，表层网格水深0~1 m），海洋生物地球化学模块采用BFM5.2，海冰模块采用CICE4.0。

该模型由意大利莱切（邮编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《地球科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果，其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）作者群体的参考资源。

CMIP6由世界气候研究计划（World Climate Research Programme, WCRP）下属的耦合建模工作组（Working Group on Coupled Modelling, WGCM）协调推进。第六阶段继承了此前由气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导的多轮项目成果，依托地球系统网格联合会（Earth System Grid Federation, ESGF）、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。原始数据托管于联邦化数据节点集群并实现部分复制，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）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个全球气候模型与45家科研机构及组织的模拟成果。项目官网：https://pcmdi.llnl.gov/CMIP6。
