The determination of the land geoid and marine involves different data sets calculation strategies. It is a hot issue at present to construct unified land–ocean quasi-geoid by fusing multi-source in coastal areas, which great significance construction integration. Classical integral algorithms such as Stokes theory find it difficult deal with heterogeneous gravity signals, so scholars have grad...

The determination of high-quality mean dynamic topography (MDT) over island areas faces multiple challenges, due to the error in a global geopotential model (GGM) as well contaminated waveforms satellite altimetry data and scarcity surveyed gravimetric observations. We study potential enhance regional quasi-geoid/MDT by using recently released altimetric gravity airborne Numerical experiments P...
