The geopotential model EGM2008 has been tested in the Southern part of India by fitting gravity data. These data have beencollected by the National Geophysical Research Institute of India and have been also used to estimate the geoid in this region. For the comparisons a total of 16013 gravity values have been considered. Previous global geopotential models have been also computed on these gravity points to analyze their performance as related to EGM2008. Furthermore, this new model has been compared with the local geoid estimate that is available in this region. The results prove that, in terms of gravity anomaly, in the Southern India region, EGM2008 is better than any other existing model. As for the geoid undulation, the differences between the local South India geoid and EGM2008 are less than 2 m (in absolute value) and are partially correlated with the topography.
