%X Zhongshan Station (= 76 22 E, = 69 22 S) is located in the larseman hills, East Antarctica. From March 1991 to January 2001, continuous observation of gravity earth tide was carried out by using lacoste et gravimeter. This data set is the observation data of 1999. The earth tide refers to the phenomenon of periodic deformation of the solid earth under the action of the tidal force of the sun and the moon. When the earth is regarded as a spherical rigid body, the vertical component of the tidal force vector makes the gravity value of the point change, which is called the earth's gravity solid tide. It is a function of the position and time of the point on earth.
