Auxiliary 3D displacements of the center mass of the total Earth with respect to the center mass of the solid Earth without atmosphere caused by atmospheric pressure loading. The sum of this displacement and the displacement wrt of the total mass, is the displacement with respect to the center of solid Earth, i.e. center of figure.
