High-resolution and continuous hydrological products have tremendous importance for the prediction of water-related trends enhancing capability sustainable water resources management under climate change human impacts. In this study, we used random forest (RF) extreme gradient boosting (XGBoost) methods to downscale groundwater storage (GWS) from 1° (~110 km) 1 km by downscaling Gravity Recover...

Abstract. This study assesses the detailed water budget of Saq–Ram Aquifer System (520 000 km2) over 2002–2019 period using satellite gravity data from Gravity Recovery And Climate Experiment (GRACE). The three existing GRACE solutions were tested for their local compatibility to compute groundwater storage (GWS) variations in combination with soil moisture datasets available land surface model...

The number of precipitation products at the global scale has increased rapidly, and accuracy these directly affects hydro-meteorological simulation forecast. Therefore, applicability should be comprehensively evaluated to improve their application in hydrometeorology. This paper performances six widely used southwest China by quantitative assessment contingency assessment. were Tropical Rainfal...

Surface displacements measured by the Global Navigation Satellite System (GNSS) integrate elastic response of solid Earth to regional and local hydrologic loading signals provide an opportunity for near-real-time monitoring terrestrial water storage variations. Here, we estimate spectral information hydrology-induced vertical surface deformation based on spherical Slepian basis functions recove...

Abstract Land-cover change is a critical concern due to its climatic, ecological, and socioeconomic consequences. In this study, we used multiple variables including precipitation, vegetation index, surface soil moisture, evapotranspiration obtained from different satellite sources study their association with land-cover changes in the Mediterranean region. Both observational modeling data were...

For 15 years, the Gravity Recovery and Climate Experiment (GRACE) mission have monitored total water storage (TWS) changes. The GRACE ended in October 2017, 11 months later, Follow-On (GRACE-FO) was launched May 2018. Bridging gap between both missions is essential to obtain continuous mass To fill gap, we propose a new approach based on remove–restore technique combined with an autoregressive ...
