Numerical aspects of a spline-based multiresolution recovery of the harmonic mass density out of gravity functionals

Autor: Volker Michel, Kerstin Wolf

Publikováno v: Geophysical Journal International. 173:1-16

We show the numerical applicability of a multiresolution method based on harmonic splines on the 3-dimensional ball which allows the regularized recovery of the harmonic part of the Earth's mass density distribution out of different types of gravity

The GRACE event calendar

Autor: Vishwakarma, Bramha Dutt

GRACE mission is a joint venture of NASA and GFZ. This mission was launched to provide with unprecedented accuracy, estimates of the global high resolution models of the Earth’s gravity field. The study of time-variability of Earth’s gravity fiel

Harmonic Spline-Wavelets on the 3-dimensional Ball and their Application to the Reconstruction of the Earth´s Density Distribution from Gravitational Data at Arbitrarily Shaped Satellite Orbits

Autor: Fengler, Martin J., Michel, Dominik, Michel, Volker

We introduce splines for the approximation of harmonic functions on a 3-dimensional ball. Those splines are combined with a multiresolution concept. More precisely, at each step of improving the approximation we add more data and, at the same time, r
