Global vertical velocity estimates from observation-based geostrophic meridional velocities

Annual vertical velocity (w) estimates from observation-based geostrophic velocities within the global themocline during the 1994-2018 period.

The w fields are computed following the methodology described in Cortés-Morales and Lazar, submitted applied to the ARMOR3D [Mulet et al., 2013] geostrophic meridional velocities. The boundary condition used is the Ekman pumping vertical velocities computed from ERA5 wind stress.
