This study presents a solution of the '1 cm Geoid Experiment'(Colorado Experiment) using
spherical radial basis functions (SRBFs). As the only group using SRBFs among the …

Gravity field modelling in coastal region faces challenges due to the degradation of the
quality of altimeter data and poor coverage of gravimetric measurements. Airborne …

The development of the global geopotential model (GGM) broadens its applications in
ocean science, which emphasizes the importance for model assessment. We assess the …

A regional approach using Poisson wavelets is applied for gravity field recovery using the
GOCE (Gravity Field and Steady‐State Ocean Circulation Explorer) gravity gradient tensor …

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 as the …

Abstract The Hong Kong Principal Datum (HKPD) is the currently adopted official geodetic
vertical datum at the Hong Kong territories. The HKPD is practically realized by heights of …

Abstract Number of detailed geoid models have been developed to convert geodetic heights
measured by the Global Navigation Satellite Systems (GNSS) to heights in the Hong Kong …

The marine gravity field recovery close to land/island is challenging owing to the scarcity of
measured gravimetric observations and sorely contaminated satellite radar altimeter-derived …

In many modern local and regional gravity field modelling concepts, the short-wavelength
gravitational signal modeled by the residual terrain modelling (RTM) technique is used to …

In this study, a new data-adaptive network design methodology called k-SRBF is presented
for the spherical radial basis functions (SRBFs) in regional gravity field modeling. In this …
