CMIP6 input data usage information for IPCC WGI AR6 figure 4.26

The record contains information on input dataset usage and citation information from the WCRP Coupled Model Intercomparison Project Phase 6 (CMIP6) for the generation of figure 4.26 of the Sixth Assessment Report of Working Group I of the Intergovernmental Panel on Climate Change (IPCC AR6 WGI). CMIP6 data that were used as input to this figure follow the Data Reference Syntax. Persistent Identifiers (PIDs) for data identification (provenance) are available for individual datasets as Handle IDs. DOIs for data citation are available on the following dataset collections: CMIP6 DOIs contain all datasets provided by an Earth System model to a CMIP6 experiment. The data subsets of CMIP6 dataset collections used in the IPCC AR6 WGI have DOIs at this granularity of a model contribution to an experiment. The AR6 subset DOIs are included because they reside in a long-term preservation archive hosted by the IPCC Data Distribution Centre (DDC). The uploaded human-readable csv file provides a list of datasets/Handle IDs used for the generation of this figure grouped by the corresponding dataset collections they belong to. The machine-actionable json-ld file describes the record as Complex Citation Object (see Agarwal et al., 2024, https://doi.org/10.5281/zenodo.14106602) in a preliminary standard, using the following vocabulary to specify the different functions of the contained Linked Digital Objects: Credit (input dataset collection to be cited/to which credit is to be assigned), Provenance (dataset contributing information to the generation of the DataProduct), archivedAt (dataset collection with long-term preservation), DigitalDocument (referenced papers containing further information), DataProduct (generated final dataset), ImageObject (visualization of the DataProduct), SoftwareSourceCode (software applied to generate the DataProduct), Chapter (IPCC AR6 WGI chapter in which the DataProduct is used/referenced). Use and cite this record when referring to the generation of IPCC WGI AR6 figure 4.26.本记录包含用于生成政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）第一工作组第六次评估报告（IPCC AR6 WGI）图4.26的输入数据集使用情况，以及世界气候研究计划（World Climate Research Programme, WCRP）耦合模式比较计划第六阶段（CMIP6）的引用信息。本图所用的CMIP6输入数据遵循数据参考语法（Data Reference Syntax）。用于数据识别（溯源）的持久标识符（Persistent Identifiers, PIDs）以句柄标识符（Handle IDs）的形式为各数据集提供唯一标识。数据引用所需的数字对象唯一标识符（Digital Object Identifier, DOI）可通过以下数据集集合获取：CMIP6的DOI包含地球系统模型为某一CMIP6试验提交的全部数据集。IPCC AR6 WGI中使用的CMIP6数据集集合子集，其DOI以模型对试验的贡献为粒度进行标注。本记录收录AR6子集DOI，因其存储于IPCC数据分发中心（IPCC Data Distribution Centre, DDC）维护的长期保存档案中。 上传的可读格式CSV文件列出了本图生成所用的数据集及句柄标识符，并按其所属的数据集集合进行分组。可机器读取的JSON-LD文件以初步标准将本记录定义为复杂引用对象（Complex Citation Object，详见Agarwal等，2024，https://doi.org/10.5281/zenodo.14106602），并使用以下词汇表明确所包含的链接数字对象的各类功能：引用主体（Credit，即需被引用或需被赋予贡献的输入数据集集合）、溯源数据（Provenance，即为数据产品生成提供信息的数据集）、存档位置（archivedAt，即具备长期保存能力的数据集集合）、数字文献（DigitalDocument，即包含进一步信息的参考文献）、数据产品（DataProduct，即生成的最终数据集）、图像对象（ImageObject，即数据产品的可视化成果）、软件源代码（SoftwareSourceCode，即用于生成数据产品的软件）、章节（Chapter，即数据产品被使用或引用的IPCC AR6 WGI章节）。 若提及IPCC AR6 WGI图4.26的生成工作，请引用本记录。
