The Antarctic plateau can be the best astronomical observatory site on the earth because of its very dry air and low temperature. We have observed atmospheric turbulence in the boundary layer (up to the altitude of 1000m above ice surface) by SODAR during JARE-48. We obtained valid continuous data of turbulence strength and three dimensional wind speed from Dec. 21, 2006 to Jan. 14, 2007. Our data show clear correlation between turbulent layer height and solar elevation. Also reported is the jolt measured during transportation from Cape Town to Dome Fuji.
