     abstract = "{Data from the Gravity Recovery and Climate Experiment (GRACE) satellite
        mission can be used to monitor changes in terrestrial water
        storage (TWS). In this study, we exploit the TWS observations
        from a new temporal gravity field model, Tongji-Grace2018, which
        was developed using an optimized short-arc approach at Tongji
        University. We analyzed the changes in the TWS and groundwater
        storage (GWS) in each of the nine major river basins of the
        Chinese mainland from April 2002 to August 2016, using Tongji-
        Grace2018, the Global Land Data Assimilation System (GLDAS)
        hydrological model, in situ observations, and additional
        auxiliary data (such as precipitation and temperature). Our
        results indicate that the TWS of the Songliao, Yangtze, Pearl,
        and Southeastern River Basins are all increasing, with the most
        drastic TWS growth occurring in the Southeastern River Basin.
        The TWS of the Yellow, Haihe, Huaihe, and Southwestern River
        Basins are all decreasing, with the most drastic TWS loss
        occurring in the Haihe River Basin. The Continental River Basin
        TWS has remained largely unchanged over time. With the exception
        of the Songliao and Pearl River Basins, the GWS results produced
        by the Tongji-Grace2018 model are consistent with the in situ
        observations of these basins. The correlation coefficients for
        the Tongji-Grace2018 model results and the in situ observations
        for the Yellow, Huaihe, Yangtze, Southwestern, and Continental
        River Basins are higher than 0.710. Overall, the GWS results for
        the Songliao, Yellow, Haihe, Huaihe, Southwestern, and
        Continental River Basins all exhibit a downward trend, with the
        most severe groundwater loss occurring in the Haihe and Huaihe
        River Basins. However, the Yangtze and Southeastern River Basins
        both have upward-trending modeled and measured GWS values. This
        study demonstrates the effectiveness of the Tongji-Grace2018
        model for the reliable estimation of TWS and GWS changes on the
        Chinese mainland, and may contribute to the management of
        available water resources.}",
