Sažetak
The main scope of the GEOMED2 project is the determination of a high-accuracy and high-resolution geoid model for the Mediterranean Sea using land and marine gravity data and the more recent Global Geopotential Models, those based on GOCE/GRACE data. The processing methodology is based on the well-known remove-compute-restore procedure and both stochastic and integral/spectral methods for the determination of the geoid and the rigorous combination of heterogeneous data. All the available gravity observations for the wider Mediterranean basin were collected, validated, homogenized and unified in terms of their horizontal coordinates and gravity systems, so as to derive a reliable gravity data base to be used for the determination of the geoid. The so-determined geoid model can form the basis for height-system unification in the Mediterranean area. Also, by comparison with altimeter data, this geoid can be used to derive high-resolution models of the Mean Dynamic Topography that will allow estimating the marine circulation in the Mediterranean Sea. The final delivered products of this project will be the geoid estimate in the Mediterranean area, the Mean Dynamic Topography of the Mediterranean Sea and the implied circulation model.
