摘要: An alternative “direct method” to “mean dynamic topography” (MDT) computations using satellite altimetry-derived sea surface” (MSS) and “global geopotential model” (GGM), without direct application of the geoid, is devised. The developed approach, which based on derivation an equipotential surface gravity field Earth that fits global MSS in least squares sense, formulated via a constrained optimization problem. validity our method numerically tested by computing MDT model DNSC08 EGM2008 GGM as input data.
