Abstract
At the Institute of Geodesy (IfE) we are estimating the monthly gravity field spherical harmonic coefficients with our inhouse developed software "GRACE-SIGMA". The software provides state-of-the-art monthly gravity field solutions. After determining the sphericial harmonic coefficients from the least squares adjustment a detailed analysis of the post-fit range-rate residuals is conducted. Different techniques are used to reveal and analyse spatio-temporal patterns in the residuals. In the Poster/Presentation we want to address these mismodeled/unmodeled effects and their impact on gravity field determination.
