Derived dataset for "Drought–carbon-source event transmission in the Yellow River Basin under CO2 variability: a 3-D event perspective"

This dataset provides the derived data supporting the manuscript entitled “Drought–carbon-source event transmission in the Yellow River Basin under CO2 variability: a 3-D event perspective”. The dataset contains five Excel files generated during the event-based analysis. These files support the identification of drought-related events, carbon-source events, drought–carbon-source event propagation, Vine copula-based dependence modelling, and propagation group classification in the Yellow River Basin. The files included in this dataset are: 1. Result_Data_for_VineCopula.xlsx This file contains the processed variables used for Vine copula-based dependence modelling among drought, CO2 variability, and carbon-source-related variables. 2. Result_Events_NEP.xlsx This file contains the identified NEP-related carbon-source events and their derived event characteristics. 3. Result_Events_SPEI_CO2.xlsx This file contains the identified SPEI–CO2 drought-related events used to characterize drought events under CO2 variability. 4. Result_Propagation_Analysis_SPEI_CO2_NEP.xlsx This file contains the drought–carbon-source event propagation analysis results, including the transmission relationships between SPEI–CO2 drought-related events and NEP-related carbon-source events. 5. Result_Propagation_Groups_SPEI_CO2_NEP.xlsx This file contains the classification results of drought–carbon-source event propagation groups and supports the analysis of different propagation types. These data were used to support the main event identification, dependence analysis, propagation assessment, and figure/table generation procedures reported in the manuscript. The original remote sensing, meteorological, carbon flux, and ancillary datasets are available from the data providers cited in the manuscript. Spatial coverage: Yellow River Basin, China. Data type: Derived tabular data in Microsoft Excel format.本数据集为题为《CO₂变异下黄河流域干旱-碳源事件传导：三维事件视角》的学术手稿提供支撑性衍生数据。 本数据集包含基于事件分析流程生成的5个Excel文件，可支撑黄河流域干旱相关事件、碳源事件、干旱-碳源事件传导、基于藤Copula（Vine copula）的依赖关系建模以及传导组分类等相关分析。 本数据集包含的文件如下： 1. 《Result_Data_for_VineCopula.xlsx》：本文件包含用于干旱、CO₂变异与碳源相关变量间藤Copula（Vine copula）依赖关系建模的经预处理变量集。 2. 《Result_Events_NEP.xlsx》：本文件包含已识别的与净生态系统生产力（Net Ecosystem Production，NEP）相关的碳源事件及其衍生事件特征参数。 3. 《Result_Events_SPEI_CO2.xlsx》：本文件包含已识别的、用于表征CO₂变异下干旱事件的标准化降水蒸散指数-CO₂（SPEI-CO₂）干旱相关事件数据集。 4. 《Result_Propagation_Analysis_SPEI_CO2_NEP.xlsx》：本文件包含干旱-碳源事件传导分析结果，涵盖标准化降水蒸散指数-CO₂干旱相关事件与净生态系统生产力相关碳源事件间的传导关联关系。 5. 《Result_Propagation_Groups_SPEI_CO2_NEP.xlsx》：本文件包含干旱-碳源事件传导组的分类结果，可支撑不同传导类型的相关分析工作。 本数据集所提供的数据用于支撑手稿中报道的核心事件识别、依赖关系分析、传导评估以及图表生成流程。原始遥感、气象、碳通量及配套辅助数据集可从手稿中引用的相关数据提供方获取。 空间覆盖范围：中国黄河流域。数据类型：微软Excel（Microsoft Excel）格式的衍生表格数据。
