     abstract = "{The Gravity Recovery and Climate Experiment (GRACE) and its successor
        GRACE Follow-On (GRACE-FO) provide a new observational method
        for monitoring large-scale Terrestrial Water Storage Anomalies
        (TWSA). However, existing TWSA records cover only the period
        since 2002 and exhibit mission discontinuities, which limits
        their applicability in studies of long-term hydrological
        changes. Therefore, this study proposes a TWSA component
        reconstruction framework coupled with time-series decomposition,
        the VIC hydrological model and machine learning to reconstruct a
        monthly-scale TWSA dataset at a resolution of
        0.25{\textdegree}{\texttimes}0.25{\textdegree} from 1961 to 2022
        in Xinjiang, and to verify its reliability using JPL and CSR
        Mascon products and multi-source observation data. The main
        findings of this study include: (1) During the GRACE observation
        period, the reconstructed TWSA exhibits high consistency with
        CSR-Mascon and JPL-Mascon in spatiotemporal distributions:
        approximately 70\% of grids have CC > 0.6, over 60\% have NSE >
        0.6, and more than 80\% of grid cells have RMSE < 15 cm and DISO
        < 6. (2) Independent validation based on groundwater-level
        observations showed that the standardized reconstructed
        groundwater storage anomalies derived from reconstructed TWSA
        were positively correlated with standardized groundwater-level
        anomalies in all groundwater-validation grids (CC = 0.23--0.81),
        indicating that the reconstructed results can generally
        characterize the temporal consistency of groundwater variations.
        Meanwhile, the reconstructed TWSA shows strong correlations (CC
        > 0.60) with CNRD v1.0 and TerraClimate runoff depth in 57\% and
        85\% of the areas, respectively, with local CCs exceeding 0.85,
        indicating that the reconstructed TWSA can reasonably reflect
        the hydrological response characteristics of runoff variations.
        (3) Reconstruction results show that the TWSA in Xinjiang
        exhibited a predominantly downward trend from 1961 to 2022, with
        60.8\% of the study area showing a downward trend. The intra-
        annual variation shows a surplus in winter and deficits in
        spring and summer, and the seasonal amplitude and long-term
        trend exhibit significant spatial heterogeneity. The
        reconstructed long-term TWSA dataset provides a data foundation
        for diagnosing water storage evolution, monitoring hydrological
        droughts, and assessing water resources in Xinjiang.}",
