MASS CHANGE IN ANTARCTIC AERA BASED ON GOCE ORBITS DATA
1)Institute of Geoscience and Environment Engineering,Southwest Jiaotong University, Chengdu 610031
Abstract Ten gravity field models up to 60 degree and order are recovered based on one year GOCE orbits data and short arc integral approach. The correlated error among spherical harmonic coefficients is studied. And the mass change within the range of Antarctic 30° is inverted using the recovery gravity field model sequences. The results show that the mass change at B point (-75°, 250°) is approximate -9.15 cm/a which is detected by GOCE satellite, it means that the ice sheet of B point is melting.
Key words ：
GOCE
precise science orbit
mass change of ice sheet in Antarctic
