Vaisala's latest study examines the performance of Tritons in complex terrain.
Because Triton is the wind energy industry's leading remote sensing system, we have a unique opportunity to study their accuracy over millions of hours of real-world commercial wind industry deployments all over the globe - in addition to individual verification studies at wind turbine test centers.
In 2016, Vaisala released its first global comparison study of Triton performance. The study used data from thirty pairs of Tritons and co-located met towers in flat terrain, and concluded that on average, Triton's uncertainty matches that of towers, at about 1%.
Because flow curvature bias is one of the leading concerns in using remote sensors to measure wind in complex terrain, Vaisala partnered with WindSim to develop a method that mitigates the effects of complex flow on wind measurements collected by remote sensing units.
Vaisala's latest study is entitled "Validation of Triton Wind Profiler Measurements in Complex Terrain, Using WindSim CFD-Based Flow Curvature Correction." This paper analyzes data drawn from dozens of Triton-and-tower pairs in complex terrain affected by flow curvature. The study tested the correction methodology, and more important, it demonstrated the accuracy of Tritons when used in complex terrain.

"The accuracy of remote sensing data has widely been recognized as on a par with that of met towers in all aspects - except when it comes to operating in complex terrain. The use of CFD simulations to adjust Triton data removes this concern, levelling the playing field in terms of data quality, and allowing developers to take full advantage of the Triton’s versatility."

Remote Sensing Data Services from Vaisala
Do you want to quickly reduce or eliminate flow curvature bias from your wind data on a site affected by complex wind flow? Or, have you performed a side-by-side measurement campaign to verify the performance of your remote sensing device on an individual site?
Vaisala now offers remote sensing data services to users of the Triton Wind Profiler. Our Remote Sensor CFD Correction Service is ideal for anyone who wants to remove flow curvature bias from data collected in complex sites. And our Triton Verification Analysis, performed by a team of experts who have done hundreds of Triton-and-met-tower verification studies, is ideal both for smaller firms without a met services department or for firms whose teams are already overworked.
