"surface_downward_y_stress_correction"@en . "The surface called \"surface\" means the lower boundary of the atmosphere. \"Surface stress\" means the shear stress (force per unit area) exerted by the wind at the surface. A downward stress is a downward flux of momentum. Over large bodies of water, wind stress can drive near-surface currents. \"Downward\" indicates a vector component which is positive when directed downward (negative upward). \"y\" indicates a vector component along the grid y-axis, positive with increasing y. \"Downward y\" indicates the ZY component of a tensor. A downward y stress is a downward flux of momentum, which accelerates the lower medium in the direction of increasing y and and the upper medium in the direction of decreasing y. A positive correction is downward i.e. added to the ocean."@en .
