Global to Local Moho Estimate Based on GOCE Geopotential Model and Local Gravity Data

摘要: Collocation approach has been applied to get a global Moho model in spherical approximation based on GOCE geopotential model. A simple single layer model, with known density contrast, considered and linearized relationship between the harmonic coefficients of anomalous potential those depth derived. This allows covariance propagation from gravity depth. The derived functions are then used collocation estimate In order be as close possible reductions for signal related topography/bathymetry have applied. Simulated real data tests performed obtained solution compared estimates available literature.
