Better wind data accuracy -- Acoustic radar
1 February 2009
A measuring device using acoustic radar is being developed by researchers at the University of Salford in Britain to enable wind project developers to optimally locate their wind turbines. As well as measuring wind speeds like most mast-mounted sensors, the sodar device will take into account variations in wind caused by local terrain and atmospheric turbulence without the need for a physical structure. The £330,000 development project is expected to produce a working model within two-and-a-half years. "This project draws upon existing research into the use of sodar to give more accurate measurements of local atmospheric conditions," says the university's Sabine von Hünerbein, who is leading the research. "However, we will be refining the technique and introducing new algorithms which will, for the first time, produce highly accurate data. This has great potential to help the green energy sector improve the accuracy of its data."
