On the differences and compatibility of global and GOCE-based models of the gravity field of the Earth

Original language description

Global models of the gravity field of the Earth that involve terrestrial measurements and GOCE-based gravity field models represent two different sources of information on the gravity field of the Earth. The aim of this paper is to focus on their combination. The problem has an essential tie to potential theory and it is not difficult to realize that by nature it is an overdetermined problem. Therefore, methods typical for the solution of boundary-value problems of potential theory will be applied together with an optimization approach, target function and regularization techniques. The aim also is to demonstrate the effect of the two different data sources on the resulting solution and to show its spectral and space domain interpretation. In particular, the use of gravity field information contained in satellite-only models of the gravity field of the Earth or alternatively in GOCE gradiometric data in common with terrestrial gravity measurements is discussed in the paper.
