The EGM96 geopotential model (Lemoine et al., 1998) was for long time the most accurate reference model for many applications in Earth’s sciences. Taking advantage of recent terrestrial gravity, elevation and altimetry data as well as the results from satellite gravity missions, a new global gravity model, EGM2008, has been calculated by the National Geospatial-Intelligence Agency (NGA) of the USA. The official Earth Gravitational Model EGM2008 has been publicly released by the U.S. National Geospatial-Intelligence Agency (NGA) EGM Development Team. This model is complete to degree and order 2159, and contains additional spherical harmonic coefficients extending to degree 2190 and order 2159. This contribution is a report of the validation results of the preliminary pre-released combined geopotential model PGM07A and the final model EGM2008 (Pavlis et. al., 2008) over Argentina. Comparisons with other well-known Earth Gravity Models like EGM96 (Lemoine et. al., 1998) and EIGEN-GL04C (Förste et al., 2006) are also presented.
