Abstract:
The quality of the orbit ephemerides is crucial for the computation of the Sea Surface Height (SSH). Conversely, analyzing the impact of precise orbit ephemerides on SSH performances enables to describe their impact at different temporal scales and to detect remaining weakness in the orbit solution with a very fine precision.
In 2014, a large panel of evolutions was developed in order to be integrated in the GDR-E orbit standards. They had been qualified and compared to the previous GDR-D orbit standards for Jason-2 mission.
During 2015, the final version of the POE-E orbit standards is made available for Jason1, Jason-2 and Cryosat-2.
This poster synthesizes the final quality of these orbits, with respect to the previous standards, using mono-mission and multi-missions diagnosis. In particular, the effect of the different orbit solutions concerning long term trends and inter-annual signatures observed on the Sea Surface Height are addressed. Climatic scales stability is analyzed as well as regional and higher frequency signals.
