| Definition | "Height_above_X" means the vertical distance above the named surface X. "Sea surface height" is a time-varying quantity. A reference ellipsoid is a regular mathematical figure that approximates the irregular shape of the geoid. A number of reference ellipsoids are defined for use in the field of geodesy. The geoid is a surface of constant geopotential with which mean sea level would coincide if the ocean were at rest. To specify which reference ellipsoid is being used, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention. The standard name for the height of the sea surface above the geoid is sea_surface_height_above_geoid. The standard name for the height of the sea surface above mean sea level is sea_surface_height_above_mean_sea_level. | ||
