The Earth Gravitational Model (EGM) development team released the Preliminary Gravitational Model (PGM2007A) and the final EGM2008. These models are completed to degree and order 2160 and contain additional spherical harmonic coefficients extending to degree 2190 and order 2160. A total of 1,190 GPS points available on Bench Marks (GPS/BM) in South America and 85,018 mean free air gravity anomalies in a grid of 5’ are used to evaluate the following gravity field models: EGM96, EIGEN-GL04S1, EIGEN-GL04C, GGM02S, GGM02C, PGM2007A and EGM2008. The results are presented in terms of statistics and histograms of the discrepancies between GPS geoid heights as well as gravity disturbances and the seven important Global Geopotential Models. The modern models represent a substantial improvement on the gravitational field representation in South America and EGM2008 shows the best result compared to previous models.
