Bathymetry inversion using the deflection of the vertical: A case study in South China Sea
Geodesy and Geodynamics, 2022 The deflection of the vertical is one of the essential products of altimetry. However, unlike gravity and vertical gravity gradients, it is seldom used in bathymetry inversion.

Using satellite altimetry leveling to assess the marine geoid
Geodesy and Geodynamics, 2020 Based on the concept of Global Position System (GPS)/leveling, the satellite altimetry leveling (SAL) is first proposed to evaluate the marine geoid. SAL is derived by the difference among the mean sea surface (MSS), mean dynamic ocean topography (MDT ...
