Abstract

Summary

With the launch of the Jason-1 but particularly the Cryosat-2 three times as much altimetric data have become available to marine gravity field determination using satellite. The impact of this new geodetic mission data is huge everywhere in the global ocean with the quality of the altimetric gravity field matching marine gravity observations in many regions. In particularly the Arctic Ocean, this huge accuracy improvement is demonstrated through comparison with high quality airborne data flown north of Greenland in 2009. An improvement of nearly 50% is seen in comparison with older gravity fields like DTU10 and EGM08 in the region
