66 -- Acoustic Wind Profiler

The United States Department of Agriculture (USDA), Forest Service, North Central Research Station, East Lansing, Michigan has a requirement for an acoustic wind profiler. Included in the suite or required measurements for the monitoring network is lower atmospheric wind conditions. Sonic and cup anemometers are being used to monitor winds near the surface and within forest vegetation layers. Acoustic wind profilers are needed to monitor winds above the vegetation layers. The acoustic enclosure standard will be mounted on the top of an existing tower. The profiler will be used along with a mobile acoustic wind profiler to provide a more complete three-dimensional picture of wind conditions. The specifications for the acoustic wind profiler are as follows: number of elements - 64 Piezoelectric transducers, Frequency range - 2850-4750 Hz (user selectable), Acoustic output power - 2.5 W selectable, Number of frequencies - up to 10 base frequencies selectable, Emission/Reception angles - 0, +/-20, +/-26 9 beams selectable, Number of vertical layers - 100 maximum selectable, Thickness of vertical layers - 5-100 m selectable, Lowest measurement height - 10 m beginning of lowest layer, Maximum range - 200-500 m 15 min average time, Averaging time - 1 min to 60 min selectable, Accuracy of horizontal wind speed - 1.0-0.3 m/s (typ) in multi-frequency mode, Accuracy of vertical wind speed - 0.03-0.1 m/s (typ) in multi-frequency mode, Accuracy of wind direction - 2-3 degrees (typ) at wind speeds above 2 m/s.
