The Gravity Recovery and Climate Experiment (GRACE) has monitored global gravity changes since 2002. Gravity changes are considered to represent hydrological water mass movements around the surface of the globe, although fault slip of a large earthquake also causes perturbation of gravity. Since surface water movements are expected to affect earthquake occurrences via elastic surface load or po...

Aimed at mapping time variations in the Earth’s gravity field, the Gravity Recovery and Climate Experiment (GRACE) satellite mission is applicable to access terrestrial water storage (TWS), which mainly includes groundwater, soil moisture (SM), and snow. In this study, SM and accumulated snow water equivalent (SWE) are simulated by the Global Land Data Assimilation System (GLDAS) land surface m...

The Gravity Recovery and Climate Experiment (GRACE) its successor, the GRACE Follow-On (GRACE-FO) gravity satellite missions, have been providing monthly field solutions for almost 20 years, enabling a unique opportunity to monitor large-scale mass variation processes. anomaly time series Aral Sea region has obtained period of April 2002 January 2022. method determining from GRACE-FO improved b...

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

The launch of the Gravity Recovery and Climate Experiment (GRACE) space gravity mission opened new horizons to the scientific community for environmental monitoring. Through the provision of estimates of temporal changes in the Earth’s gravity field, the products generated from the GRACE mission have enabled studies of mass balance changes in polar regions, deformation caused by very large eart...

the earth’s gravity field dedicated missions, champ, grace and goce have opened up a new era for the study of the earth’s gravity field. the missions measure different functionals on the earth’s gravitational potential which are represented in terms of the stokes coefficients or the so-called geopotential models. the mapping process of the observations into the coefficients is called recovery o...

Abstract. A complete global flood event record would aid researchers to analyze the distribution of floods and, thus, better formulate and manage disaster prevention reduction policies. This study used Gravity Recovery Climate Experiment (GRACE) terrestrial water storage precipitation data combined with high-frequency filtering, anomaly detection potential index methods successfully extract his...

Flooding is projected to increase with climate change in many parts of the world. Floods in cold regions are commonly a result of snowmelt during the spring break-up. The peak river flow (Qpeak) for the Mackenzie River, located in northwest Canada, is modelled using the Gravity Recovery and Climate Experiment (GRACE) satellite observations. Compared with the observed Qpeak at a downstream hydro...

The 27 February 2010 Mw 8.8 Maule, Chile, earthquake ruptured over 500 km along a mature seismic gap between 341 S and 381 S—the Concepción–Constitución gap, where no large megathrust earthquakes had occurred since the 1835Mw 8.5 event. Notable discrepancies exist in slip distribution and moment magnitude estimated by various models inverted using traditional observations such as teleseismic ne...
