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.
