MPI-M MPI-ESM1.2-LR model output prepared for CMIP6 DAMIP hist-volc

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.DAMIP.MPI-M.MPI-ESM1-2-LR.hist-volc' 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 MPI-ESM1.2-LR climate model, released in 2017, includes the following components:
aerosol: none, prescribed MACv2-SP, atmos: ECHAM6.3 (spectral T63; 192 x 96 longitude/latitude; 47 levels; top level 0.01 hPa), land: JSBACH3.20, landIce: none/prescribed, ocean: MPIOM1.63 (bipolar GR1.5, approximately 1.5deg; 256 x 220 longitude/latitude; 40 levels; top grid cell 0-12 m), ocnBgchem: HAMOCC6, seaIce: unnamed (thermodynamic (Semtner zero-layer) dynamic (Hibler 79) sea ice model).
The model was run by the Max Planck Institute for Meteorology, Hamburg 20146, Germany (MPI-M) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, land: 250 km, landIce: none, ocean: 250 km, ocnBgchem: 250 km, seaIce: 250 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`完整数据引用语法模板发布的`CMIP6.DAMIP.MPI-M.MPI-ESM1-2-LR.hist-volc`相关数据集。

2017年发布的MPI-ESM1.2-LR气候模式包含以下组成模块：气溶胶模块：无预设配置，采用MACv2-SP方案；大气模块为ECHAM6.3谱模式（谱截断T63，经纬度网格为192×96，垂直层数47层，顶层气压0.01 hPa）；陆面模块为JSBACH3.20；陆冰模块：无预设或采用固定边界条件；海洋模块为MPIOM1.63（双极GR1.5网格，近似1.5°分辨率，经纬度网格为256×220，垂直层数40层，顶层网格水深范围0~12 m）；海洋生物地球化学模块为HAMOCC6；海冰模块为未命名热力学（Semtner零层）动力学（Hibler 1979）海冰模式。

该模式由德国汉堡20146地区的马克斯·普朗克气象研究所（Max Planck Institute for Meteorology, Hamburg 20146, Germany，简称MPI-M）以原始标称分辨率运行：气溶胶模块分辨率250 km，大气模块250 km，陆面模块250 km，陆冰模块无配置，海洋模块250 km，海洋生物地球化学模块250 km，海冰模块250 km。

本数据集作为国际协作的耦合模式比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》（GMD）特刊：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。第六阶段依托此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导完成的前期研究基础，基于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）及众多相关协作活动完成数据落地实施。原始数据存储于分布式联邦数据节点集群并实现部分复制，IPCC依赖的绝大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 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45家科研机构及组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
