Time-variable gravity field determination from GRACE-FO data at AIUB [PDF]
, 2019 Time-variable gravity field determination from GRACE-FO data at AIUB We study gravity field determination from GRACE-FO satellite-to-satellite tracking using the inter-satellite-link (KBR and LRI) and kinematic positions of the satellites as observations.

Validation of GRACE and GRACE-FO Mascon Data for the Study of Polar Motion Excitation
Remote Sensing, 2021 In this study, we calculate the hydrological plus cryospheric excitation of polar motion (hydrological plus cryospheric angular momentum, HAM/CAM) using mascon solutions based on observations from the Gravity Recovery and Climate Experiment (GRACE) and ...

Caspian Sea level based on GRACE-FO [PDF]
, 2021 Abstract The level of the Caspian Sea has decreased by about 13 cm in 2019. In this study, the Caspian Sea level has been studied based on GRACE-FO observations from 2018 to 2021. Its linear trend has been analyzed to examine it more closely. The linear trend is about -8 cm / year.

Spatiotemporal Characterization of Geophysical Signal Detection Capabilities of GRACE‐FO
Geophysical Research Letters, 2021 AbstractThe intersatellite range measurements between the Gravity Recovery and Climate Experiment Follow‐On (GRACE‐FO) satellite pair enable mapping time variations in Earth's gravity field. The Laser Ranging Interferometer (LRI) and Microwave Instrument (MWI) provide independent range measurements.

Topside Ionosphere Sounding From the CHAMP, GRACE, and GRACE‐FO Missions
Radio Science, 2023 AbstractSatellites in Low Earth Orbit (LEO) are essential for sounding the topside ionosphere. In this work, we present and validate a data set of Total Electron Content (TEC) and in situ electron density observations from the Gravity Recovery And Climate Experiment (GRACE) and GRACE‐Follow‐On missions as well as a TEC data set from the CHAllenging ...
