AlpArray program is a European initiative to advance our understanding of orogenesis and its relationship to mantle dynamics, plate reorganizations, surface processes and seismic hazard in the Alps-Apennines-Carpathians-Dinarides orogenic system. The initiative integrates present-day Earth observables with high-resolution geophysical imaging of 3D structure and physical properties of the lithosphere and of the upper mantle, with focus on a high-end seismological array. As part of this project, the AlpArray Gravimetric Research Group (AAGRG) was established in the same year, the aim of which was to compile a homogeneous gravity dataset, which will be used to create a basic gravity map of the total Bouguer anomalies.
