摘要	A flux system deployed on a moored buoy has been described,which is capable of directly estimating the airsea fluxes after removing the contamination in the signal due to buoy motion.A triple loop fitting method has been demonstrated for determining the three angular offsets between measurement axes of the sonic anemometer and motion pack.The data collected in an experiment in the Northern Huanghai Sea is used to correct the three sonic anemometer measurements of turbulent wind for buoy motion.The effective removal of wave-scale motion from the spectra and cospectra are demonstrated.Estimates of along-wind momentum flux,sensible heat flux and latent heat flux calculated by the eddy correlation method based on data obtained by sonic anemometer 81000V are shown to be in the same trend and scale with those determined by the bulk aerodynamic method after motion correction.The motion correction not only greatly improve the estimation of the momentum flux but also has a great impact on the calculated sensible heat flux.
