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：本数据集是国际协调的耦合模式比较计划第六阶段（CMIP6，详见《Geoscientific Model Development》（简称GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出数据。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）作者群体的研究资源。

CMIP6由耦合模式工作组（Working Group on Coupled Modelling，WGCM）协调，隶属于世界气候研究计划（World Climate Research Programme，WCRP）。第六阶段延续了此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的各阶段工作，并依托地球系统网格联盟（Earth System Grid Federation，ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关配套活动完成实施。原始数据存储于联邦数据节点集群并进行部分副本存储；IPCC依赖的绝大多数数据正由德国气候计算中心（Deutsches Klimarechenzentrum，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结果，参与机构约45个。项目官网：https://pcmdi.llnl.gov/CMIP6。
