OLIV3 (Observation-based LInear Vorticity Vertical Velocities) is a new global dataset of large-scale oceanic vertical velocities. It is derived from the geostrophic linear vorticity balance, combining in situ and satellite, meridional velocities and wind stress. Comparisons with reanalysis and observation-based products show that OLIV3 captures the large-scale vertical flow, its climatology, and temporal variability, providing a better description of the ocean interior than Ekman pumping.
