%X Turbulence variance and flux of temperature fluctuation derived by simulatneous measurements with sonic anemometer-thermometer and fine wire thermometer have been compared for re-evaluating the contamination of humidity and horizontal wind in sonic temperature Good agreement between two measurements is obtained if proper correction is applied to the statistics of sonic temperature In the near neutral stratification the correction for both humidity and horizontal velocity must be considered when using sonic temperature, but in other stability ranges it is precise enough to correct the data with humidity only Our results show the sonic temperature spectrum levels increase at high frequency end as in the previous study However, the increase is less significant in fine wire temperature spectrum This is cause by noise aliasing and it becomes severe due to lower temperature resolution in the sonic measurement
