By mitigating temporal aliasing errors caused by unresolved high-frequency atmospheric and oceanic mass variations, MAGIC is expected to provide substantially improved estimates of terrestrial water storage (TWS) changes. To date, MAGIC's performance has been evaluated primarily using global gravity field inversions. I...

Observations of mass changes in the cryosphere are critical to understanding the impact of climate change and constraining global projections of sea-level rise. Observations from satellite gravimetry missions, satellite altimetry, and Surface Mass Balance (SMB) models provide differing estimates of mass change at diffe...

Recent advances in optical clock technology offer the possibility of directly sensing differences in the Earth’s gravitational potential through frequency comparisons between satellites. This study investigates the performance of different satellite formation-flying architectures for recovering the time-variable gravit...

Global static gravity models produced as spherical harmonic (SH) coefficients have a wide range of applications in geodesy, geophysics, oceanography, and satellite dynamics. It has been established that more information can be extracted from the observations using regional modeling compared to global spherical harmonic...
