Brief Description
Modern space geodesy has becomes a powerful remote-sensing tool for many applications in Earth system sciences -- not just for any individual discipline, but truly interdisciplinary. The techniques include the conventional ones (Global Positioning System, satellite-laser ranging, very-long-baseline interferometry, satellite radar altimetry, and their technology upgrades) and new ones under experiment or development (laser altimetry; imaging lidar, wide-swath radar altimetry, synthetic aperture radar SAR and Interferometric SAR, satellite-to-satellite tracking, etc.). Together they make possible space-borne, precise measurements of Earth's rotation, gravity field, time-variable gravity, sea level variations, ice sheet topography, land topography and surface deformations, ground motions, and many more, for applications in Earth sciences as well as natural hazards studies. This half-day session welcomes submissions on all aspects of the techniques, principles, development, and modeling.
