[1] Monitoring hydrological redistributions through their integrated gravitational effect is the primary aim of the Gravity Recovery and Climate Experiment (GRACE) mission. Time-variable gravity data from GRACE can be uniquely inverted to hydrology, since mass transfers located at or near the Earth’s surface are much larger on shorter timescales than those taking place within the deeper Earth a...

Evapotranspiration (ET) plays an important role in the hydrological cycle of river basins. Studying ET Yellow River Basin (YRB) is greatly significant for scientific management water resources. Here, we made full use advantages Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) gravity satellites monitoring large-scale changes to calculate terrestrial storage anomaly (TW...

Abstract The gap between the Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-on mission (GRACE-FO) is a crucial problem, leading to discontinuous global mass change information from time-variable gravity field solutions. We aim use improved Multichannel Singular Spectrum Analysis (MSSA) fill reconstruct continual signals in this study. one-year filled with MSSA based on Release 06 ...

Groundwater management practices need to take hydrogeology, the agro-climate and demand for groundwater into account. Since agroclimatic zones have already been demarcated by the Government of India, it would aid policy makers to understand the status of groundwater recharge and discharge in each agroclimatic zone. However, developing effective policies to manage groundwater at agroclimatic zon...

[1] We quantify gravity changes after great earthquakes present within the 10 year long time series of monthly Gravity Recovery and Climate Experiment (GRACE) gravity fields. Using spherical harmonic normal-mode formulation, the respective source parameters of moment tensor and double-couple were estimated. For the 2004 Sumatra-Andaman earthquake, the gravity data indicate a composite moment of...

A good understanding of the accuracy Global Positioning System (GPS) surface displacements provided by different processing centers plays an important role in load deformation analysis. We estimate noise level both vertical and horizontal directions for four representative GPS time series products, compare results with derived from Gravity Recovery Climate Experiment (GRACE) gravity measurement...

13 There is increasing interest in using GRACE (Gravity Recovery and Climate Experiment) 14 satellite data to remotely monitor groundwater storage variations; however, comparisons with 15 ground-based well data are limited but necessary to validate satellite data processing, 16 especially when the study area is close to or below the GRACE footprint. The Central Valley is a 17 heavily irrigated ...

The impact of new geoid height models on estimates of the ocean circulation, now available from the Gravity Recovery and Climate Experiment (GRACE) spacecraft, is assessed, and the implications of far more accurate geoids, anticipated from the European Space Agency’s (ESA) Gravity and Ocean Circulation Explorer (GOCE) mission, are explored. The study is based on several circulation estimates ob...
