[S-GD01] Gravity and Geoid

Wed. May 23, 2018 10:45 AM - 12:15 PM A09 (Tokyo Bay Makuhari Hall)

convener:Takayuki Miyazaki(Geospatial Information Authority of Japan), Keiko Yamamoto(National Astronomical Observatory of Japan), Chairperson:Nawa Kazunari, Nisijima Jun

Recent precise gravity measurements lead to advances in many kinds of applications, e.g., investigation of internal structure of the Earth and Moon, studies of earthquake, volcano, subsidence, landslide and tsunami, monitoring ice mass balance, and so on. In this session, we call wide range of papers related to topics of gravity and geoid, including theory of gravity field, absolute/relative gravity measurements/observations, data analysis of satellite gravity missions, and development of gravity sensors.
