Abstract

Using gravity / gravity gradient data for Moho inversion, one of the key steps is how to extract the Moho information data precisely from raw measurements. Here we mainly discussed:①In order to eliminate the error of point mass model used by GEMMA Moho research team, we choose Tesseroid in space domain and harmonic analysis and synthesis method in frequency domain; ②The reasonable use of priori crustal model. Based on GOCO03S model, we provide the gravity gradient disturbing results of three main components which are for Moho inversion. Finally, all experiment results are discussed and analyzed in this paper.

Key words： GOCE; Moho; extraction of gravity gradient
