Supporting datasets and codes for manuscript “Contrasting GPP–SIF coupling patterns reveal functional divergence of grassland carbon sequestration on the Tibetan Plateau”----- GPP and SIF time series.zip # Resampled growing-season GPP (Gross Primary Productivity) and SIF (Solar-Induced Chlorophyll Fluorescence) time series for grasslands on the Tibetan Plateau (2000–2022) ----- EEMD_analysis_result.zip # This dataset contains raster results derived from the EEMD (Ensemble Empirical Mode Decomposition) analysis of GPP and SIF time series over the Tibetan Plateau grasslands. -----driving factors_GPP.csv # This dataset contains raster turning-point data representing the types of GPP (Gross Primary Productivity) trend changes and their potential driving factors across the grasslands of the Tibetan Plateau.It provides spatial information on vegetation productivity trends, climate variability, topographic features, soil properties, and human activities. ----- driving factors_SIF.csv # This dataset contains raster turning-point data representing the types of SIF trend changes and their potential driving factors across the grasslands of the Tibetan Plateau. # Codes for conducting analysis and generating plots-------EEMD_analysis1.R # Codes for EEMD analysis and Figure 2,3,4. -------Driving factors_analysis2.R # Code for the driving mechanism analysis and Figures 5, 6, 7, and 8
