|Description||The surface called "surface" means the lower boundary of the atmosphere. A velocity is a vector quantity. "y" indicates a vector component along the grid y-axis, when this is not true latitude, positive with increasing y. "Geostrophic" indicates that geostrophic balance is assumed. "sea_level" means mean sea level. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. surface_geostrophic_sea_water_x_velocity_assuming_sea_level_for_geoid is the variable part of surface_geostrophic_sea_water_x_velocity. The assumption that sea level is equal to the geoid means that the stationary component of ocean circulation is equal to zero.|
