Validation of GRACE/GRACE-FO Solutions Using Caspian Sea Level Change
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingTo validate gravity recovery and climate experiment (GRACE)/ GRACE follow-on (GRACE-FO) gravity solutions, we compare satellite altimetry observations of Caspian Sea level (CSL) change with CSL estimates from satellite gravity from April 2002 to ...

Mass Variations in Antarctica From GRACE and GRACE-FO [PDF]
, 2023 Changes on the Earth’s surface causes changes in the gravity field. Through dedicated satellite gravity missions such as Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow On (GRACE-FO), this change can be measured. Mass redistribution on the surface of the Earth such as water movement causes these changes.
