Abstract

We discuss same concepts related to the estimation of covariance parameters in the numerical treatment of gravity downward continuation. We aim explicitly at the determination of weighting factors, regularization parameters, and residual data correlations in the inversion of satellite gravity data for spherical harmonic coefficients. Special attention is given to the efficient treatment of large—sized data sets, having in mind data reduction and model validation fore. g. the GOCE mission, and to the derivation of probability density functions.
