Zhongshan Station is located in the Lashmann Hills of Southeast Antarctica. The 22nd team conducted continuous observations of gravity tides using the Lacoste ET gravimeter from March 2006 to November 2006. This dataset is the observation data of the team, which includes the gravity solid tide observation data from the Chinese Antarctic Expedition in 2006. Solid tide refers to the phenomenon of periodic deformation of the solid Earth caused by the tidal forces of the sun and moon. When the Earth is viewed as a spherical rigid body, the vertical component of the tidal force vector causes a change in the gravity value at that point, which is called the Earth's gravitational solid tide. It is a function of the location and time of the point on Earth.
Continuous observation of gravity solid tide.
Use Lacoste ET gravimeter for continuous observation.
This instrument belongs to the optical observation project, and the observation environment is sometimes affected by station lighting, weather conditions, and moonlight, resulting in high data quality. The observation instrument records data in duplicate, and according to the scientific cooperation agreement signed between the polar research institutes of China and Japan, each party retains one copy.
