[S-GD23] Gravity and Geoid

Wed. May 27, 2015 4:15 PM - 6:00 PM 102A (1F)

Convener:*Jun Nishijima(Department of Earth Resources Engineering, Graduate School of Engineering, Kyushu University), Yuichi Aoyama(National Institute of Polar Research), Chair:Jun Nishijima(九州大学大学院), Takayuki Miyazaki(Geospatial Information Authority of Japan)

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.
