The next generation of wind assessment hardware may be tower-less. Several studies have shown that SOund Detection And Ranging (SODAR) is an effective way to assess a wind resource at today’s turbine heights. It is quickly becoming the preferred choice of assessment among prospective wind developers. In fact, a recent study conducted by the National Renewable Energy Laboratory shows that data collected by the Triton is equally valid as data collected from tradition met towers. Take a look at the study here.
SODAR systems, unlike conventional meteorological towers, use sound rather than radio waves for measurement. 60-100 meter met towers record data through loggers and sensors mounted on the tower while SODAR utilizes remote communications such as satellites to receive and report data. Although the SODAR system is only about 2 meters high, it can measure wind by sending sonic beams up into the atmosphere, producing audible “chirps” that listen for return “echos” or signals. By precisely measuring the time delay and frequency of the chirp’s echo, SODAR can accurately measure wind speeds at heights up to 200 meters.
National Wind Assessments owns Triton Sonic Wind Profilers that you can rent and deploy for various projects. Find out today if the Triton will work for your project.
