G54A:
Geodetic Measurements of the Earth's Elastic Response to Surface Mass Variability II


Session ID#: 8225

Session Description:
Surface mass variability causes the Earth to respond elastically, resulting in deformations of the crust and mantle lithosphere. Modern geodetic tools, including GPS, InSAR, and Gravimetry (including GRACE) can measure these types of lithosphere loading effects at a high accuracy. Here, we invite presentations that bridge geodetic observations (e.g. GPS, InSAR, GRACE, ICESat, cryosat-2) to elastic processes to analyze mass movements on land, in the ocean, the cryosphere and the atmosphere. This includes, but is not limit to, predicting surface deformation based on numerical modeling or independent loading data, and comparing it to the geodetic measurements. We particularly welcome presentations making use of geodetic observed deformation in local- to global-scale applications, to infer surface loading variations, decipher elastic and non-elastic deformation signals, or aim at refining Earth structure models. The session intends to enhance geodesy’s applications to the fields of hydrology, cryospheric and solid Earth studies.
