Regional Ground Surface Mass Variations Inversed by Radial Point-mass Model Method with Spatial Constraints

Radial point-mass model method is the disturbance gravity downward continuation in essence, which is an ill-posed problem. In general, the regularization method is an efficient way to get the reliable solution. To solve this problem, the radial point-mass model method is improved by using Helmert va...
