| Abstract: | Sea surface height(SSH)is composed of geoid undulation and sea surface topography(SST).SST focuses on long-wave,hence,in the inverse Vening-Meinesz formula,a smaller integral radius could reduce long-wave error from SST,and improve the accuracy of the gravity.Satellite altimetry data and shipping measured gravity data are used,marine gravity is calculated by different integral radius,and conclusion is that 30′-60′ is the most suitable integral radius. |

| Keywords: | satellite altimetry vertical deviation inverse operation inverse Vening-Meinesz formula integral radius |
