BackForward Variable: Ocean surface currents (vector)

Definition
Full name Ocean surface currents (vector)
Definition Water flow on ocean surface - Physical unit: [ cm/s ] - Accuracy unit: [ cm/s ] intended as vector error, i.e. the module of the vector difference between the observed vector and the true vector.
Measuring Units cm/s Uncertainty Units cm/s
Horizontal Res Units km Vertical Res Units
Stability Units cm/s (Stability /decade)

 

Comment: From remote sensing viewpoint, the geostrophic component can be derived from Ocean dynamic topography. Ageostrophic components only occasionally observed. In 2016 GCOS IP this is called surface geostrophic current
