Temporal variations of geoid heights over Kazakhstan from GRACE–FO data and their relation with hydrological changes in the Caspian Sea and seismic activity

Frontiers in Earth Science
We quantify temporal variations of geoid heights (Δ N ) across Kazakhstan during 2019–2024 using satellite gravimetry, and relate these changes to recent extreme hydrological and seismic events.

GRACE/GRACE-FO Satellite Assessment of Sown Area Expansion Impacts on Groundwater Sustainability in Jilin Province

Sustainability
Jilin Province, an important commodity grain base in China, relies on groundwater resources for its agricultural development. The implementation of a series of policies, including agricultural subsidies and food security policies, has led to a rapid ...

Substantial root-zone water storage capacity observed by GRACE and GRACE/FO

Hydrology and Earth System Sciences
. Root-zone water storage capacity (Sr) – the maximum water volume available for vegetation uptake – bolsters ecosystem resilience to droughts and heatwaves, influences land–atmosphere exchange, and controls runoff and groundwater recharge.

Calibration and Characterisation of GRACE-FO Magnetometers

Magnetic field data from satellite missions play a significant role in characterizing and understanding space weather conditions. Satellite magnetic field observations from different altitudes and local times are necessary to disentangle the complex processes contributing to each observation of Earth’s magnetic field and study the various ...

Evaluation of GRACE and GRACE-FO derived-products for water storage assessment in Moroccan aquifers: analysis of drought and human-induced impacts

Geocarto International
Groundwater overexploitation in Morocco’s arid and semiarid regions poses a sustainability challenge. The Gravity Recovery and Climate Experiment (GRACE) offers valuable groundwater monitoring potential, despite its coarse resolution.

GRACE-FO monthly solutions using the GRACE-SIGMA software

2019
In this contribution we present gravity field monthly solutions from GRACE Follow-On (GRACE-FO) Level-1B sensor data. The monthly solutions are computed with the GRACE-SIGMA software developed at the Institute of Geodesy, Leibniz University Hannover. The solutions are obtained using a two-step approach. In a first step, the orbits of the two satellites

Filling the data gap between GRACE and GRACE-FO based on a two-step reconstruction method

International Journal of Digital Earth
Terrestrial water storage represents both surface and subsurface water resources and plays a crucial role in the global hydrological cycle. The Gravity Recovery and Climate Experiment (GRACE) satellite mission provides large-scale and high-stability ...

Elastic Displacement of the Solid Earth and GRACE/GRACE‐FO Response to Variations in Global Lake and Reservoir Storage

Journal of Geophysical Research: Solid Earth
We estimate the solid Earth's elastic response and change in equivalent water thickness produced by 983 global natural lakes and artificial reservoirs. Using the altimetry and LandSat based lake water storage compilation of Yao et al.
