Abstract:

The relative rough sea surface height above the reference ellipsoid can be determined from altimetry data. The calculated height value contains geoid height, the mean dynamic topography and the dynamic ocean topography. In order to remove the dynamic ocean topography from altimetry data the crossover adjustment technique was applied through the following steps: (1) determination of crossover locations, and modeling the temporal change of dynamic sea surface topography with bias and tilt parameters; (2) crossover adjustment for determining the parameters of model. The approach was experimentally tested on ENVISAT satellite altimetry data of cycle 81st on the East Sea. The experimental results show the capability of crossover adjustment technique for removing the dynamic ocean topography from altimetry data.
