The climate anomaly in the Amazon River basin (ARB) has a very important influence on global change and always been focus of scientists from all over world. To fill 11-month data gap between Gravity Recovery Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) missions, we fused TWSC results six solutions by using generalized three-cornered hat least square method to improve reliability result...

A quantitative understanding of changes in water resources is crucial for local governments to enable timely decision-making maintain security. Here, we quantified natural-and human-induced influences on the terrestrial storage change (TWSC) Sichuan, Southwest China, with intensive consumption and climate variability, based data from Gravity Recovery Climate Experiment (GRACE) its Follow-on (GR...

NASA’s Gravity Recovery and Climate Experiment (GRACE) has already proven to be a powerful data source for regional groundwater assessments in many areas around the world. However, the applicability of GRACE data products to more localized studies and their utility to water management authorities have been constrained by their limited spatial resolution (~200,000 km2). Researchers have begun to...

The Earth’s time-variable gravity field is of great significance to study mass change within the system. Since 2002, NASA-DLR Gravity Recovery and Climate Experiment (GRACE) its successor GRACE follow-on mission provide observations monthly changes in Earth with unprecedented accuracy resolution by employing low-low satellite-to-satellite tracking (LLSST) measurements. In addition LLSST, models...

The terrestrial water storage anomaly (TWSA) observed by the Gravity Recovery and Climate Experiment (GRACE) satellite its successor GRACE Follow-On (GRACE-FO) provides a new means for monitoring floods. However, due to coarse temporal resolution of GRACE/GRACE-FO, understanding flood occurrence mechanisms short-term floods are limited. This study utilizes statistical model reconstruct daily TW...

Water storage change has implications not only for the hydrological cycle, but also for sustainable water resource management in especially semi-arid river basins. Satellite/remote sensing techniques have gained increasing application in monitoring basin and regional hydrological processes in recent decades. In this study, the latest version of GRACE (Gravity Recovery and Climate Experiment) is...

Since 2002, the GRACE satellite mission provides estimates of the Earth’s dynamic gravity field with unprecedented accuracy. Differences between monthly gravity fields contain a clear hydrological signal due to continental water storage changes. In order to evaluate GRACE results, the state-of-the-art WaterGAP Global Hydrological Model (WGHM) is applied to calculate terrestrial water storage ch...
