    Abstract
  • In order to study the vertical deformation detailing characteristics of the crustal atmospheric loading of GNSS station in China, the 36month atmospheric loading effect of six reference stations in the crustal movement observation network of China have been calculated and analyzed based on the Green function integral and simplification method. The results show that atmospheric loading is the important factor to cause the vertical deformation of the crust. The regional variation and vertical deformation in the earth's crust caused by atmospheric loading effect are the largest in northeastern China and western Xinjiang area. The correction of atmospheric loading effect can further improve the vertical accuracy of GPS.
