Rethinking Sodar for Wind Site Profiling

ImageAccurate assessment of the resource at potential wind-energy sites is becoming more critical. The 60m met towers most commonly used for site assessment are decreasingly effective as turbines grow taller. Sodar devices, which measure wind speed and direction at any height up to about 200m, are a potential solution. Although manned sodar products are now common for short-term profiling, they have many shortcomings for long-term assessment. In this article, the author describes the innovations of Second Wind's Triton sonic wind profiler, which was designed to replace met masts for many assessment applications.
