Observing geophysical signals in the Climate and Earth System through Geodesy

Session ID#: 80760

Session Description:
Geodetic observations are becoming increasingly important for studying and monitoring of the climate system. Data-driven quantification of water mass fluxes through boundaries of Earth’s different regions and spheres provides important insights to other geoscience communities and informs model validation and improvement. Changes in regional sea level and ocean circulation are observed by altimetry and gravimetry. Alterations of the terrestrial water cycle lead to changes in the water table which may cause surface deformation sensed by GNSS stations/InSAR measurements as well as mass changes observed by satellite/ground gravimetry. Mass changes in the ice sheets and glaciers are detectable by both geometrical and gravimetric techniques.


This session aims to cover innovative ways to use geodetic satellite measurements and their combination with in-situ observations for Earth science applications. We welcome approaches which tackle the problem of separating signals of different geophysical origin, by taking advantage of model output and/or advanced processing/estimation techniques.
