Short summary

We study time-varying vertical deformation signals in the European Alps by analyzing GNSS position time series. We associate the deformation signals to geophysical forcing processes, finding that atmospheric and hydrological loading are by far the most important cause of seasonal displacements. Recognizing and filtering out non-tectonic signals allows us to improve the accuracy and precision of the vertical velocities.
