gravity gradients remains costly, and achieving comprehen-sive global ocean coverage continues to be a challenge The GOCE satellite, equipped with electrostatic accelerometer-based gravity gradiometers, provides global gravity data (Sil-vestrin et al ,2012;Rummel et al ,2011;Marks et al , 2013) Despite this, its resolution is limited in providing

Understanding the Earth's subsurface structure is a primary goal in geophysics, and in particular gravity anomaly data assist as a vital tool for revealing otherwise subtle geological features (e g , Mehanee, 2014; Essa et al , 2020) Gravity anomalies indicate variations in the Earth's gravity field resulting from alterations in the density of the Earth's interior (e g Dumberry and Bloxham
- SDUST2023VGGA: a global ocean vertical gradient of gravity anomaly . . .
Abstract Satellite altimetry is a vital tool for global ocean observation, providing critical insights into ocean gravity and its gradients Over the past 6 years, satellite data from various space agencies have nearly tripled, facilitating the development of high-precision ocean gravity anomaly and ocean vertical gradient of gravity anomaly (VGGA) models This study constructs a global ocean
