Description:
The gravimetric geoid in the area of Syowa Station, a Japanese research station located in Lutzow-Holm Bay, East Antarctica, have been calculated by combining a GOCE-based global gravity model and in-situ gravity data obtained from the Japanese Antarctic Research Expedition (JARE) surveys. More precisely, the in-situ data sets consist of land gravity data collected since 1967, shipborne data collected since 1985 and airborne gravity data collected in 2006. A remore-restore procedure has been applied, using the release 5 of the GOCE direct solution (DIR R5) as the long-wavelength reference model and computing geoid heights at 1'x1' spatial resolution by means of least-squares collocation. Geoid heights are delivered only at the points where the formal errors is better than 0.20 m.
