We present a comprehensive view of the origin, significance and implications of topographic
effects in gravimetry. These are gravitational effects of topographic masses that are present …

Recent applications in Earth sciences require geoid models to be determined with a sub-
centimetre internal error. Regional models of the geoid are usually determined using …

Since 2006, several different groups have computed geoid and/or quasigeoid (quasi/geoid)
models for the Auvergne test area in central France using various approaches. In this …

This paper is written as a progression of the ongoing discussion in geodesy about the merits
of the Molodensky height system versus the classical height system. It is a rebuttal of a …

The horizontal components of the airborne gravity vector are equivalent to the deflection of
the vertical at the flight level and contain signals of the slope of Earth's gravity field. We test …

Inland satellite altimetry has gained traction over the past decade and is now routinely used
to monitor the water levels of rivers, lakes and reservoirs. The accuracy of such inland water …

We estimate the uncertainty of the modelled geoid heights based on the standard deviations
of the topographic mass density variation. We model the geoid using the one-step …
