Determination of Gravity Anomalies over the Arabian

Gravity anomalies derived from satellite altimetry are progressively anomalies-derived from multi-mission satellite altimetry-with gravity anomalies by the EGM96 global geopotential model. The results show some significant differences among these gravity data sources. Ocean satellite altimetry implied free-air gravity anomalies have had the shortest wavelength removed during the processing to generate the optimal solution between multiple radar altimeter missions. Compute gravity anomalies by LSC using along-track, differeced geoidal heights and height slopes. Gravity Anomalies over the Arabian Sea (latitudes: 0-25oN and longitudes: 35 – 70oE) is computed by using along track deflections of vertical and grid along track deflections of vertical using Shepard's method of gridding procedure and finally the gravity anomalies were computed using the inverse Vening-Meinesz formula we used altimeter data from Topex/Poseidon, Jasonl, Geosat, ERSI and ERS2 missions
