Sonic anemometer measurement of atmospheric turbulence
Abstract
The use of sonic anemometers in the study of atmospheric turbulence is discussed. The principles of operation of the instrument are described, together with procedures used in measuring horizontal and vertical wind velocity components. The effect of the array dimensions and the configuration of the acoustic paths on the spectral responses at wavelengths approaching the size of the array is examined, together with factors affecting the choice of sampling rates and run lengths.
