On the Combination of Terrestrial Data and GOCE Based Models in Earth?s Gravity Field Studies: Compatibility and Spectral Weighted Optimization
Original language description
The purpose of this paper is to discuss the impact of terrestrial and GOCE gravity field data on the solution representing the combination of these information in Earth?s gravity field studies. Potential theory is of key importance in this field, but theproblem considered is overdetermined by nature. Therefore, methods typical for the solution of boundary-value problems have to be used together with optimization concepts. In particular the compatibility of the mentioned data sources is examined and theform of an integral representation of the solution is investigated in dependence of the combination scheme and the spectral weighted optimization applied. For this purpose in the first step the optimized solution is expressed by a series of spherical harmonics, thus interpreted in spectral domain. Subsequently, summation techniques are used in order to find a closed form of the respective kernel functions (Green?s functions) in the integral representation of the solution. This shows exp
