G34A:
Gravity, Geoids, and Geopotential Reference Frames: Data Inputs, Implementations, and Evolution with Time II


Session ID#: 8499

Session Description:
This session welcomes all abstracts related to the collection and processing of gravimetric data and/or its use in computing gravimetric geoid models or regional geopotential models generally. Also relevant are abstracts discussing regional geopotential reference frames (height systems). Topics of interest include: the processing and collection of any gravimetry data, such as surface gravity (ground and marine), airborne gravity, altimetry, and astronomical deflection data; modeling theory; model validation; tracking gravity and geoid changes; Glacial Isostatic Adjustment modeling; regional mass movements measured by gravity (terrestrial or satellite) or GPS; forward modeling of topography and density; calculation of physical height quantities, such as orthometric heights or geopotential numbers.
