G51B:
Hydrological Signals in Geodetic Data: New Observations, Models, and Techniques I Posters

Submit an Abstract to this Session



Session ID#: 25333

Session Description:
Geodesy is becoming increasingly important for observing the hydrological cycle and its effects on solid Earth shape. For example, GPS and InSAR measurements respectively provide high temporal and spatial resolution to study natural hydrologically-related deformation and monitor anthropogenic groundwater extraction and recharge, whereas GRACE is helping to track changes in the global terrestrial water storage. Signals of loading from changes in surface and groundwater storage are seen from basin to continental scale. Additionally, GPS reflectometry is in operational use for monitoring soil moisture and snow depth at continuous GPS stations in the western USA and Canada. In light of these developments, we invite contributions describing new observations and models of hydrological signals in geodetic time series and/or imaging. Studies exploring deformation induced by loading extraction/recharge, techniques for removing hydrological signals from geodetic time series, or teleconnections between terrestrial and oceanic phenomena, are particularly encouraged.
