摘要
The results of calibrations of the airspeed measurement, distance constant and cosine response for a sensitive propellor (vane) anemometer are described. A triad of these anemometers may be used to measure wind velocity, and the estimated uncertainty in this measurement is evaluated for a typical triad and a range of wind directions. The propellor anemometers tested provide sensitivity similar to that of sonic anemometers for research, but at much lower cost (although for a narrower range of wind conditions). Large arrays of the anemometers allow the spatial and temporal structure of wind turbulence to be measured directly. The anemometers have been used for several years, and are robust enough for micrometeorological research.
