Local gravity field modelling in rugged terrain using spherical radial basis functions: case study for the Canadian Rocky Mountains
Conference paper - R Tenzer, R. Klees, TF Wittwer
We analyze the performance of a least-squares approximation of the gravity field using spherical radial basis functions (SRBF's) in rugged mountains.@en

Comparison of regional and global grace gravity field models at high latitudes
In this study we address the question of whether regional gravity field modeling techniques of GRACE data can offer improved resolution over traditional global spherical harmonic solutions@en
