Coriolis is a Data Assembly Centre (DAC) for French and some Europeans Argo projects.

The role of a DAC is to collect, decode, control and distribute data from more than 200 profiling floats from 7 countries and 11 scientific projects. Coriolis manages 3 families of floats (Provor, Metocean, Apex) with a total of 17 different versions.

All float data managed by Coriolis DAC are distributed in real-time on ARGO GDAC (Global Data Assembly Centre) and GTS  (the WMO global network) by way of Météo-France.
