     abstract = "{As China's largest inland river basin and one of the world's most arid
        regions, the Tarim River Basin is home to an extremely fragile
        ecological environment. Therefore, monitoring the water storage
        changes is critical for enhancing water resources management and
        improving hydrological policies to ensure sustainable
        development. This study reveals the spatiotemporal changes of
        water storage and its driving factors in the Tarim River Basin
        from 2002 to 2022, utilizing data from GRACE, GRACE-FO (GFO),
        GLDAS, the glacier model, and measured hydrological data. In
        addition, we validate GRACE/GFO data as a novel resource that
        can monitor the ecological water conveyance (EWC) benefits
        effectively in the lower reaches of the basin. The results
        reveal that (1) the northern Tarim River Basin has experienced a
        significant decline in terrestrial water storage (TWS), with an
        overall deficit that appears to have accelerated in recent
        years. From April 2002 to December 2009, the groundwater storage
        (GWS) anomaly accounted for 87.5\% of the TWS anomaly, while
        from January 2010 to January 2020, the ice water storage (IWS)
        anomaly contributed 57.1\% to the TWS anomaly. (2) The TWS
        changes in the Tarim River Basin are primarily attributed to the
        changes of GWS and IWS, and they have the highest correlation
        with precipitation and evapotranspiration, with grey relation
        analysis (GRA) coefficients of 0.74 and 0.68, respectively,
        while the human factors mainly affect GWS, with an average GRA
        coefficient of 0.64. (3) In assessing ecological water
        conveyance (EWC) benefits, the GRACE/GFO-derived TWS anomaly in
        the lower reaches of the Tarim River exhibits a good
        correspondence with the changes of EWC, NDVI, and groundwater
        levels.}",
