     abstract = "{The Gravity Recovery and Climate Experiment (GRACE) and GRACE follow-on
        have enabled basin- to continental-scale monitoring of global
        water storage, cryospheric mass change, and sea-level variation
        since 2002. Yet key challenges remain in coarse spatial
        resolution, signal leakage, and dependence on auxiliary models.
        This review synthesizes research progress and frontiers by
        tracking thematic evolution, methodological innovation, and
        interdisciplinary integration. Analyzing 2417 publications from
        Web of Science Core Collection (2015─2025) with CiteSpace, we
        mapped publication patterns, research hot spots, collaboration
        networks, and emerging frontiers. Three main findings stood out:
        (1) a progression from ``mission milestones'' to
        ``methodological innovation'' and ``cross-disciplinary
        expansion,'' with terrestrial water storage, gravity inversion,
        and water balance as core themes, while machine learning and
        multi-source fusion as recent foci; (2) a global collaboration
        network dominated by the National Aeronautics and Space
        Administration, the Chinese Academy of Sciences, and the German
        Research Centre for Geosciences, showing strong cooperation
        among North America, Europe, and China but limited engagement
        elsewhere; and (3) expansion in interdisciplinary areas, such as
        carbon cycle─hydrology coupling and the water─energy─food nexus,
        underscoring GRACE's role in sustainability. This study outlines
        priorities to advance GRACE applications through mission
        continuity, AI-based modeling, and high-resolution regional
        analysis, contributing to global change research and water
        resource management.}",
