Sonic anemometers have had extensive use in the scientific community. These instruments are used to measure atmospheric parameters that most rotating instruments cannot. Wind speed and wind direction or individual axes of wind velocity are most commonly measured. Along with these measurements, another parameter can be extracted from the sonic anemometer (i.e.), sonic temperature.
Since the transit time measurement method is used by sonic anemometers for wind, it is independent of temperature, relative humidity, and pressure. The common method of computing wind velocities is: Where t1 ant t2 are transit times in the opposing directions, d is the distance between the transducers.
