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).

Crustal Thickness Variations and Tectonic Settings in the Southwest Cameroon Inferred from Gravity and Topography Data
07 Feb 2022
TL;DR: In this paper , the EIGEN 6C4 gravity anomalies are interpreted to determine the lateral and vertical variations in the crust and upper mantle structure and their influence on the isostasy of the coastal plain, transition zone between the Congo Craton (CC), the Pan-African Belt (PAB), and adjacent areas.

Local quasigeoid modelling in Slovakia using the finite volume method on the discretized Earth's topography
TL;DR: In this paper, a finite volume method (FVM) is used to solve numerically the fixed gravimetric boundary value problem (FGBVP) on a 3D unstructured mesh created above the real Earth's surface.
Analysis of isostatically-balanced cortical models using modern global geopotential models
TL;DR: In this article, the geoid heights derived from global geopotential models were used to analyze the cortical features of the Tandilia structure which is assumed to be in isostatic equilibrium.
Insights into Moho depth beneath the northwestern Andean region from gravity data inversion
TL;DR: In this paper , 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, and their inversion allowed choosing the ANH2010, based on lower residual gravity and a higher agreement with seismic estimations, as the most suitable data set to gain insights into the MohO depth beneath the northwestern Andes and its relationship with previously identified tectonic features.
