[S-GD22] Gravity and Geoid

Sun. May 22, 2016 1:45 PM - 3:15 PM A05 (APA HOTEL&RESORT TOKYO BAY MAKUHARI)

Convener:*Jun Nishijima(Department of Earth Resources Engineering, Graduate School of Engineering, Kyushu University), Yuichi Aoyama(National Institute of Polar Research), Chair:Yuichi Imanishi(Earthquake Research Institute, The University of Tokyo), Takahito Kazama(Graduate School of Science, Kyoto University)

Recent precision improvement of gravity measurement contributes to the many kinds of the application (Internal structure of Earth and Moon, Earthquake, Volcano, Subsidence, Landslide, Tsunami, Monitoring ice mass
blance and so on). 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.
