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 longwave 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.
