%X Zhongshan Station is located in the Lashmann Hills of Southeast Antarctica. From March 1991 to January 2001, continuous observations of gravity tides were conducted using the Lacoste ET gravimeter. This dataset is the gravity solid tide observation data from the 8th Antarctic Expedition of China in 1991-1992. 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.
