Brief Description
Modern space geodesy has becomes a powerful remote-sensing tool for many applications in Earth 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 new ones under experiment or development (laser altimetry; imaging lidar, 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 1-day session welcomes submissions on all aspects – techniques, modeling, analysis, and geophysical interpretation.
