The new SIRGAS vertical reference system is based on the determination of an equipotential reference surface W 0 within a global definition, i.e. optimally fitting the worldwide mean sea surface. The corresponding W 0 value (mean geopotential value over the total ocean surface) is empirically estimated using different combinations of global gravity models (EGM96, TEG4, GGM02S, EIGEN-CG03C) and mean sea surface models (CLS01, KMS04, GFSC00.1 and a series of annual models from 1993 to 2001… CONTINUE READING
