[S-GD01] Gravity and Geoid

Tue. May 28, 2019 3:30 PM - 5:00 PM 303 (3F)

convener:Tokuro Kodama(Geospatial Information Authority of Japan), Daisuke Oka(Geological Survey of Hokkaido, Environmental and Geological Research Department, Local Independent Administrative Agency, Hokkaido Research Organization), Chairperson:Kazunari Nawa, Ryo Honda(山梨県富士山科学研究所)

Recent precise gravity measurements lead to advances in many kinds of applications, e.g., geophysical exploration 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, data analysis of satellite gravity missions, and development of gravity sensors.
