EVALUATION OF GROUNDWATER STORAGE CHANGES USING SATELLITE GRAVIMETRY MISSION IN PENINSULAR MALAYSIA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
Water stored beneath the Earth’s surface, known as groundwater is a major water supply for living things. The increase in human population leading to high urban development and industrial needs in Malaysia has made the use of groundwater more critical ...

Global modelling of continental water storage changes : sensitivity to different climate data sets [PDF]

, 2007
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

Altimetry, gravimetry, GPS and viscoelastic modeling data for the joint inversion for glacial isostatic adjustment in Antarctica (ESA STSE Project REGINA) [PDF]

Earth System Science Data, 2018
The poorly known correction for the ongoing deformation of the solid Earth caused by glacial isostatic adjustment (GIA) is a major uncertainty in determining the mass balance of the Antarctic ice sheet from measurements of satellite gravimetry and to ...

Gridded rates of ice-mass change in north-east Greenland from a combination of satellite gravimetry and satellite altimetry

, 2020
The gridded data set comprises rates of ice-mass change in north-east Greenland for the time period July 2010 to June 2017. For this, we combined satellite altimetry data from CryoSat-2 with satellite gravimetry data from the Gravity Recovery and Climate

Quantum gravimetry for future satellite gradiometry [PDF]

Advances in Space Research
The present electrostatic accelerometers (EA) drift at low frequencies. To address this problem, integrating a cold atom interferometry (CAI) accelerometer could be beneficial, as it offers the potential for superior long-term stability. The CAI-based accelerometers (CAI ACC) are accurate and stable, but they have some issues with long dead times and a
