Abstract: Sonic anemometers are used to measure wind speed in 1, 2, or 3 dimensional flows by relating the change in sound waves (Doppler shift) to the magnitude of the passing wind. For sonic sensors configured to measure 2D or 3D flows, it is also possible to determine the wind direction. Because of the ability to characterize such flows, sonic anemometers are essential instruments for atmospheric turbulence. Available standards for the performance testing of sonic anemometers are ASTM D 6011-96 and ISO 16622, which involves a rigorous test program that evaluates the inherent three-dimensional characteristic of sonic anemometers. For sonic sensors used in research applications, where it may be necessary to map complex flows at high resolution, such detailed test procedures for the sonic instrument may be necessary
