MPI-M MPI-ESM1.2-LR model output prepared for CMIP6 GeoMIP G6sulfur

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.GeoMIP.MPI-M.MPI-ESM1-2-LR.G6sulfur' 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（CMIP6）数据集：本数据集涵盖了针对「CMIP6.GeoMIP.MPI-M.MPI-ESM1-2-LR.G6sulfur」发布的全部数据集，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`。

MPI-ESM1.2-LR气候模式于2017年发布，其组成部分如下：气溶胶模块：无预设，采用MACv2-SP方案；大气模块：ECHAM6.3（谱模式T63；经纬度网格为192×96；共47层，顶层气压为0.01百帕）；陆面模块：JSBACH3.20；陆冰模块：无/预设；海洋模块：MPIOM1.63（双极GR1.5网格，分辨率约1.5度；经纬度网格为256×220；共40层，顶层网格水深0~12米）；海洋生物地球化学模块：HAMOCC6；海冰模块：未命名（采用热力学（Semtner零层）与动力学（Hibler 1979）海冰模式）。

该模式由德国汉堡马克斯·普朗克气象研究所（MPI-M）以本征标称分辨率运行：气溶胶模块分辨率250千米，大气模块250千米，陆面模块250千米，陆冰模块无预设，海洋模块250千米，海洋生物地球化学模块250千米，海冰模块250千米。

本数据集作为国际协调的耦合模式比较计划第六阶段（CMIP6；详见《地球科学模式发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果之一，其模拟数据可为解答核心科学问题的气候研究提供支撑，同时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由耦合模式工作组（WGCM）作为世界气候研究计划（WCRP）的组成部分协调推进。第六阶段继承了此前在气候模式诊断与相互比较计划（PCMDI）主导下完成的多阶段工作，并依托地球系统网格联盟（ESGF）与环境数据分析中心（CEDA）及众多相关配套活动完成落地。原始数据托管于联邦化数据节点集群并实现部分副本存储，IPCC依赖的多数数据正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。

该项目涵盖了全球约120个全球气候模式的模拟试验与全球约45家科研机构及组织的参与成果。项目官网：https://pcmdi.llnl.gov/CMIP6。
