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.
