Gravity Field Determination: Acquisition, Processing, and Geodetic Applications of Terrestrial, Marine, and Airborne Gravity Data
Session ID#: 75882
Session Description:
Gravity data from terrestrial, marine, and airborne instruments are fundamental to geodesy. Many other disciplines rely on either long term monitoring of the gravity field (tectonics, uplift, subsidence), or higher frequency measurements (hydrology, volcanology), or both. This session is dedicated to advances in instrumentation (both relative and absolute), acquisition techniques, processing methods, as well as novel data applications and models. Submissions on work related to gravity, such as the gravity gradient and geopotential values, are also welcomed. We invite and encourage your participation.
