Session ID#: 15710

Session Description:
Today space geodesy provides unprecedented coverage of the Earth's surface and can detect time-dependent deformation on time scales ranging from seconds to decades and over length scales ranging from meters to plate boundaries. The accurate detection of these deformation signals, in concert with accurate modelling of the processes that drive them, is of vital importance in topics ranging from studies of the seismic cycle and volcanism to the understanding of natural and anthropogenic hydrological processes. We welcome contributions on both the theoretical side - advances in algorithms for the detection of time-dependent signals in geodetic data and in the modelling of deformation processes - and on the applied side - uses of these techniques to gain insights into deformation processes in both tectonic and non-tectonic contexts - with the goal that the space geodesist can find the best practices for every step of a research project within a single session.
