| Abstract: | The basic principle of satellite gravity gradiometry technology and the characteristic of GOCE data were presented briefly.Combining a mean sea surface height model（MSS_CNES_CLS_10）,several sea surface topography models over the global ocean were calculated separately based on different degree of three gravity field models,while the results were compared and analyzed.The specific application prospect of satellite gravity gradiometry in relation to respects of ocean science was discussed,and that the development of satellite gravity gradiometry will bring about a great change for ocean science was pointed out. |
