SDUST2023GRA_MSS: the new global marine gravity anomaly model determined from mean sea surface model
The 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 ...
