The continuously updated version of Copernicus Argo floats realtime currents product is distributed from Copernicus Marine catalogue:
The Argo current product generated by Copernicus in situ TAC is derived from the original trajectory data from Argo GDAC (Global Data Assembly Center) available at:
In 2021, the GDAC distributes data from more than 15,000 Argo floats. Deep ocean current is calculated from floats drift at parking depth, surface current is calculated from float surface drift.
An Argo float drifts freely in the global ocean, performing regular observation cycles.
An observation cycle usually spreads over 10 days :
The data transmitted at each cycle contain temperature, salinity observations (and additional biogeochemical parameters if applicable), positions (gps or argos), technical data.
The ocean current product contains a NetCDF file for each Argo float. It is updated daily in real time by automated processes.
For each cycle it contains the surface and deep current variables:
