[S-GD22_1AM1] Gravity and Geoid

Thu. May 1, 2014 9:00 AM - 10:45 AM 413 (4F)

Convener:*Yuichi Imanishi(Earthquake Research Institute, The University of Tokyo), Koji Matsumoto(RISE Project Office, National Astronomical Observatory), Chair:Taku Ozawa(National Research Institute for Earth Science and Disasters), Koji Matsuo(Graduate School of Science, Kyoto University)

Gravity originates from the universal gravitation, and has fundamental effects on the structure and dynamics of the Earth, the Moon and the planets. In this session, we solicit papers on a wide variety of topics related to gravity and geoid, including the theory of the gravity field, absolute/relative gravity measurements/observations, data analysis for satellite gravity missions, and development of gravity sensors.
