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.

项目背景：本数据集作为国际协调的耦合模型相互比较项目第六阶段（CMIP6）的一部分生成（详见《地球科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）。该模拟数据为解答基础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由耦合建模工作组（WGCM, Working Group on Coupled Modelling）作为世界气候研究计划（WCRP, World Climate Research Programme）的一部分协调推进。第六阶段继承了此前由气候模型诊断与比较计划（PCMDI, Program for Climate Model Diagnosis and Intercomparison）主导的前期项目成果，依托地球系统网格联盟（ESGF, Earth System Grid Federation）与环境数据分析中心（CEDA, Centre for Environmental Data Analysis），并联合众多相关活动完成实施。原始数据托管并部分复制于联合数据节点集群，IPCC依赖的多数数据将由德国气候计算中心（DKRZ）托管的IPCC数据分发中心（IPCC DDC）进行长期保存归档。

该项目汇聚了全球约120个全球气候模型与约45个科研机构及组织的模拟成果。——项目官网：https://pcmdi.llnl.gov/CMIP6。
