The physical theoretical background, the mathematical governing equations, the absolute error, and the relative error of the dynamic method used in inferring the geostrophic current and eddy systems from the spaceborne altimeter-sensed measurements of dynamic heights or slopes have been laboriously developed. And, also, the conditions for the determination of the three dimensional density temperature field uniquely are mentioned and explained. The space-borne altimeter is shown to be the instrument for the provision of one condition, i.e., the ocean surface current condition. The three-dimensional density temperature field and its boundary conditions at the air-sea interface play dominant roles in the weather prediction and the undersea technology. The interchangeable use of the terms of density and temperature fields is valid only when the salinity can be assumed as constant.
