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.
