Abstract

European Space Agency's GOCE space gradiometer mission is anticipated to produce the mean gravity field model of the Earth with an unprecedented geoid accuracy of 1 cm rms with wavelength at 160 km or longer. We propose an international effort for the calibration and validation of GOCE gravity gradient tensor measurements and Level 2 geopotential data product (1) over a blue ice region (100x50 km^2) south of Schirmacheroase glacier, Dronning Maud Land, E. Antarctica, and (2) at regions near the Soywa station, E. Antarctica. These two regions have been well-surveyed by gravimeters, GPS traverse, tide gauge, and other instrumentations. They are currently participating or propose to participate in the calibration and validation of other spaceborne sensors, including GRACE, ICESAT and CRYOSAT. This paper reports the collaborative effort and plans for potential GOCE data product and measurement validation and description of approach for comparing in situ and other satellite data with GOCE data.
