Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.UA.MCM-UA-1-0.abrupt-4xCO2' 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 Manabe Climate Model v1.0 - University of Arizona climate model, released in 1991, includes the following components:
aerosol: Modifies surface albedoes (Haywood et al. 1997, doi: 10.1175/1520-0442(1997)010<1562:GCMCOT>2.0.CO;2), atmos: R30L14 (3.75 X 2.5 degree (long-lat) configuration; 96 x 80 longitude/latitude; 14 levels; top level 0.015 sigma, 15 mb), land: Standard Manabe bucket hydrology scheme (Manabe 1969, doi: 10.1175/1520-0493(1969)097<0739:CATOC>2.3.CO;2), landIce: Specified location - invariant in time, has high albedo and latent heat capacity, ocean: MOM1.0 (MOM1, 1.875 X 2.5 deg; 192 x 80 longitude/latitude; 18 levels; top grid cell 0-40 m), seaIce: Thermodynamic ice model (free drift dynamics).
The model was run by the Department of Geosciences, University of Arizona, Tucson, AZ 85721, USA (UA) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, land: 250 km, landIce: 250 km, ocean: 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：这些数据包含所有以“mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version”模板的完整数据引用语法（Data Reference Syntax）发布的“CMIP6.CMIP.UA.MCM-UA-1-0.abrupt-4xCO2”数据集。

1991年发布的Manabe气候模型v1.0——亚利桑那大学气候模型包含以下组件：
aerosol（气溶胶）：修改地表反照率（Haywood等人，1997，doi：10.1175/1520-0442(1997)010<1562:GCMCOT>2.0.CO;2）
atmos（大气）：R30L14（3.75×2.5度（经纬度）配置；96×80经纬度网格；14层；顶层为0.015 sigma，15 mb）
land（陆地）：标准Manabe桶式水文方案（Manabe，1969，doi：10.1175/1520-0493(1969)097<0739:CATOC>2.3.CO;2）
landIce（陆冰）：位置固定且不随时间变化，具有高反照率和潜热容量
ocean（海洋）：MOM1.0（MOM1，1.875×2.5度；192×80经纬度网格；18层；顶层网格单元为0-40米）
seaIce（海冰）：热力学冰模型（自由漂移动力学）

该模型由美国亚利桑那州图森市亚利桑那大学地球科学系（UA）以原生标称分辨率运行：气溶胶：250公里，大气：250公里，陆地：250公里，陆冰：250公里，海洋：250公里，海冰：250公里。

项目：这些数据是国际协调的耦合模式比较计划第六阶段（CMIP6；另见《地球科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的一部分。模拟数据为旨在解答基础科学问题的气候研究提供了基础，并作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者的资源。

耦合模式比较计划第六阶段（CMIP6）由耦合模式工作组（WGCM）协调，是世界气候研究计划（WCRP）的一部分。第六阶段基于此前在气候模型诊断与比较计划（PCMDI）领导下执行的各阶段工作，依赖地球系统网格联盟（ESGF）、环境数据分析中心（CEDA）及众多相关活动进行实施。原始数据托管并部分复制在联合数据节点集合上，IPCC所依赖的大部分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）存档，以供长期保存。

该项目包含来自全球约120个全球气候模型和45个机构及组织的模拟结果。——项目网站：https://pcmdi.llnl.gov/CMIP6。
