Abstract: GFZ Potsdam and GRGS Toulouse have a long-time close cooperation in the field of global gravity field determination. Here we focus on (1) GOCE gravity field determination and (2) computation of high resolution combined gravity field models. Such data products play a fundamental role in geodesy and Earth sciences, ranging from practical purposes, like precise orbit determination, to scientific applications, like investigations of the density structure of the Earth’s interior. Here we present our combined gravity field model EIGEN-6C4 which is the fourth release of EIGEN-6C (EIGEN = European Improved Gravity model of the Earth by New techniques).

A methodology for least-squares local quasi-geoid modelling using a noisy satellite-only gravity field model
TL;DR: In this paper, the authors proposed a methodology to combine a noisy satellite-only global gravity field model (GGM) with other noisy datasets to estimate a local quasi-geoid model using weighted least-squares techniques.

TL;DR: In this article , inverted gravity data from two widely used satellite-derived data sets (EGM2008 and EIGEN-6C4) and one regional airborne Bouguer gravity anomaly map (ANH2010) were used to contribute to the understanding of the Moho depth distribution beneath this region.
