Duacs is the Ssalto multimission altimeter data processing system. It serves in near-real time the main operational oceanography and climate forecasting centers in Europe and worldwide.

Ssalto/Duacs system processes data from all altimeter missions (Jason-1&2, T/P, Envisat, GFO, ERS-1 & 2 and even Geosat) to provide a consistent and homogeneous catalogue of products for varied applications, both for near real time applications and offline studies. Ssalto/Duacs Near-Real Time data are used, in particular, by Godae and its French contribution Mercator Océan. In delayed time, hundreds of teams retrieve historical Duacs datasets.
