Abstract
The objective of this study is to develop methodology to use GOCE gravity
gradients for enhanced geoid modelling and ocean circulation modelling.
In specific regions with a rough gravity field, the resolution of the geoid
may be enhanced substantially if GOCE gradiometer data are used in
addition of the GOCE spherical harmonic coefficient model (EGMs) since in
such areas the GOCE gradients contain more information than the EGM
itself. Hence, the use of gradients may lead to improve the resolution of
e.g. the marine geoid which in turn will improve the estimation of the
ocean circulation. This is tested using GOCE gravity gradient data, the
GEOCOL program (GRAVSOFT) and Reduced Point Mass (RPM) program.
Tests are carried out in the GOCINA region and in the Mediterranean basin.
Furthermore, the effect of the decreasing height of the GOCE satellite on
gravity gradients and associated MDT is investigated.
