MPI-M MPI-ESM1.2-XR model output prepared for CMIP6 HighResMIP control-1950

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.HighResMIP.MPI-M.MPI-ESM1-2-XR.control-1950' 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-XR climate model, released in 2017, includes the following components:
aerosol: none, prescribed MACv2-SP, atmos: ECHAM6.3 (spectral T255; 768 x 384 longitude/latitude; 95 levels; top level 0.01 hPa), land: JSBACH3.20, landIce: none/prescribed, ocean: MPIOM1.63 (tripolar TP04, approximately 0.4deg; 802 x 404 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: 50 km, atmos: 50 km, land: 50 km, landIce: none, ocean: 50 km, ocnBgchem: 50 km, seaIce: 50 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：此类数据涵盖所有针对`CMIP6.HighResMIP.MPI-M.MPI-ESM1-2-XR.control-1950`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`。

2017年发布的MPI-ESM1.2-XR气候模式包含以下组成部分：气溶胶模块：无自主计算模块，采用预设的MACv2-SP方案；大气模块：ECHAM6.3（谱模式T255；经纬度网格为768×384；共95层；顶层气压为0.01百帕）；陆面模块：JSBACH3.20；陆冰模块：无/采用预设数据；海洋模块：MPIOM1.63（三极TP04网格，分辨率约0.4度；经纬度网格为802×404；共40层；顶层网格水深范围0~12米）；海洋生物地球化学模块：HAMOCC6；海冰模块：未命名模式，采用Semtner零层热力学方案与Hibler 1979动力学方案的海冰模式。

该模式由位于德国汉堡20146的马克斯·普朗克气象研究所（Max Planck Institute for Meteorology, MPI-M）以原生标称分辨率运行：气溶胶模块分辨率为50千米，大气模块为50千米，陆面模块为50千米，陆冰模块无对应配置，海洋模块为50千米，海洋生物地球化学模块为50千米，海冰模块为50千米。

项目背景：此类数据是国际协调开展的耦合模式比较计划第六阶段（CMIP6；详见《地球科学模型开发（Geoscientific Model Development, GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html》）的产出成果之一。该模拟数据可为解答核心科学问题的气候研究提供支撑，同时亦可作为政府间气候变化专门委员会第六次评估报告（Intergovernmental Panel on Climate Change Sixth Assessment Report, IPCC-AR6）作者的参考资源。

CMIP6由耦合模式工作组（Working Group on Coupled Modelling, WGCM）协调开展，隶属于世界气候研究计划（World Climate Research Programme, WCRP）。第六阶段依托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建设成果，其实施依赖地球系统网格联盟（Earth System Grid Federation, ESGF）与环境数据分析中心（Centre for Environmental Data Analysis, CEDA）以及众多相关配套项目。

原始数据托管并部分复制于联邦化的数据节点集群，IPCC依赖的多数数据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。

该项目涵盖全球约120个全球气候模式的模拟成果与约45家科研机构及组织的参与。——项目官网：https://pcmdi.llnl.gov/CMIP6。
