Abstract:

Time-mean and seasonal climatology of near-surface currents for the world, at quarter-degree and 15-day resolution, calculated from observations from satellite-tracked 15-m drogued and undrogued drifters of the NOAA's Global Drifter Program. This climatology incorporates more than 29 million, six hour position/velocity estimates scattered throughout the world’s ice-free oceans, from February 1979 to June 2015.

Purpose:

A global climatology of surface ocean currents is desirable for many applications, finding use in dynamical studies, investigations of the transport and dispersion of pollutants and of biogeochemical tracers, being also relevant for ship routing and search and rescue efforts.
