Abstract : Through a validation exercise in the Kerguelen Island over 13 global, regional, and local tidal atlases, we have demonstrated the superiority of finite element high resolution model at the coast. The evaluation of different tidal geophysical corrections on the de-aliasing performance of the Jason-2 mission exhibited strong differences in the coastal domain (<10-20 km from the coast) with SLA variance reduction that can reach up to 30% from one model to another. The lack of resolution is pointed out as a possible responsible of these difference.
