CMIP6 input data usage information for IPCC WGI AR6 figure 4.22

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 4.22 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 4.22.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）第六次评估报告第一工作组（IPCC AR6 WGI）第4.22号附图的输入数据集使用情况，以及来自世界气候研究计划（World Climate Research Programme, WCRP）耦合模式比较计划第六阶段（CMIP6）的引用信息。本附图所使用的CMIP6数据均遵循数据参考语法（Data Reference Syntax）。各数据集用于识别（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标识符（Digital Object Identifier, DOIs）可通过以下数据集集合获取：CMIP6 DOIs涵盖了地球系统模型为某项CMIP6试验提供的全部数据集；IPCC AR6 WGI中使用的CMIP6数据集集合的子集，其DOIs对应于“模型对某项试验的贡献”这一粒度级别。纳入AR6子集DOIs的原因是，这些标识符存储于由IPCC数据分发中心（Data Distribution Centre, DDC）托管的长期保存档案中。 上传的可读CSV文件提供了本附图生成所用的数据集/句柄标识符列表，并按其所属的数据集集合进行分组。可机器处理的JSON-LD文件则以初步标准格式将本记录描述为复杂引用对象（Complex Citation Object，详见Agarwal等人，2024年，https://doi.org/10.5281/zenodo.14106602），并通过以下词汇表明确所包含的链接数字对象的不同功能： - 引用归属项（Credit）：需被引用/应分配引用归属的输入数据集集合 - 溯源项（Provenance）：为数据产品生成提供信息的数据集 - 长期保存项（archivedAt）：带有长期保存机制的数据集集合 - 数字文献项（DigitalDocument）：包含补充信息的参考文献 - 数据产品项（DataProduct）：生成的最终数据集 - 图像对象项（ImageObject）：数据产品的可视化成果 - 软件源代码项（SoftwareSourceCode）：用于生成数据产品的软件 - 章节项（Chapter）：数据产品所使用/引用的IPCC AR6 WGI章节 当提及IPCC AR6 WGI第4.22号附图的生成工作时，请引用本记录。
