Abstract
Recently, International Center for Global Earth Models (ICGEM) published more than 50 Global Geopotential Models (GGMs). These GGMs plays an important role in a determination of a precise geoid model. Nowadays, some of the models offer high accuracy and better resolution of the gravity field. In this study, several recent GGMs derived from satellite-only (eg. EIGEN) and combined (eg. EGM2008) will be used. Gravity anomalies derived from selected GGMs are analyzed and compared with gravity anomalies derived from terrestrial gravity observation over West Malaysia (WM). The comparison and the results of selected GGMs is shown with the residual statistic. From the results, gravity anomalies derived from combined solution Earth Gravity Model (EGM2008) with the spherical harmonic coefficients up to 2190 is the most suitable model can be use as a reference over West Malaysia.
