| Abstract: | The relation between gravity variations,vertical displacement variations and the major environment factors is studied by using the continuous observational data with superconducting gravimeter and GPS at Wuhan station.According to the surface loading theories of classical elastic-earth the contributions to the gravity and vertical displacement from atmosphere loading,non-tidal oceanic mass and continental water loading were simulated and calculated.The numerical results show that the annual amplitude variat... |
