SDUST2023GRA_MSS: the new global marine gravity anomaly model determined from mean sea surface model [PDF]
Scientific DataThe global marine gravity anomalies are primarily recovered from geoid gradients in the along-track directions obtained through satellite altimetry. However, the accuracy of the gravity model is significantly constrained by the sparse geoid gradients in ...

Comparative Study on Predicting Topography from Gravity Anomaly and Gravity Gradient Anomaly [PDF]
Remote Sensing, 2023 Owing to the dependence of algorithms on the measurement of ship soundings and geophysical parameters, the accuracy and coverage of topography still need to be improved. Previous studies have mostly predicted topography using gravity or gravity gradient,
