CMIP6 input data usage information for IPCC WGI AR6 figure 3.4

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 3.4 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 3.4.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3.4的世界气候研究计划（World Climate Research Programme, WCRP）耦合模式比较计划第六阶段（CMIP6）输入数据集的使用情况及引用信息。用于本图的CMIP6输入数据遵循数据参考语法（Data Reference Syntax）。各数据集用于标识与溯源的持久标识符（Persistent Identifiers, PIDs）以句柄标识符（Handle IDs）形式提供。用于数据引用的数字对象唯一标识符（Digital Object Identifier, DOIs）可通过以下数据集集合获取：CMIP6 DOIs集合包含地球系统模型提交至某一CMIP6试验的全部数据集。IPCC AR6 WGI中使用的CMIP6数据集子集，其数字对象唯一标识符对应于模型对某一试验的贡献粒度。AR6子集的数字对象唯一标识符已被收录，因其存储于IPCC数据分发中心（IPCC Data Distribution Centre, DDC）托管的长期保存档案中。 本次上传的人类可读的逗号分隔值（Comma-Separated Values, CSV）文件提供了用于生成本图的数据集与句柄标识符列表，并按其所属的数据集集合进行分组。可机器读取的JSON-LD文件则以初步标准将本记录描述为复合引用对象（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：Credit（需被引用或应赋予贡献的输入数据集集合）、Provenance（为数据产品生成提供溯源信息的数据集）、archivedAt（提供长期保存服务的数据集集合）、DigitalDocument（包含进一步参考信息的文献）、DataProduct（生成的最终数据集）、ImageObject（数据产品的可视化成果）、SoftwareSourceCode（用于生成数据产品的软件源代码）、Chapter（数据产品所使用或引用的IPCC AR6 WGI章节）。 当提及IPCC AR6 WGI图3.4的生成工作时，请使用并引用本记录。
