Surface current velocity estimated by data-constrained numerical model

Ocean currents are difficult quantity to measure with variability of wide spatial and temporal scales. Here we provide one of the best estimates of current velocity at the surface. This is output from a state estimate numerical model, SOSE, where ocean state satisfying the laws of physics (e.g. conservation of mass and momentum) were estimated by minimizing differences from available observed data (satellite, ship-based, etc.).
