A pair of continuous wave ZephIR 300 wind lidars have been acquired by Cornell University. The University selected ZephIR 300 in order to accurately and precisely measure the wind and turbulence interactions between the atmosphere and wind turbines.

This type of CW wind lidar gives accurate measurements of the wind speed, direction and other characteristics including Turbulence Intensity (TI). The effect of TI on wind turbines is of continual interest as the impact of irregular wind loading can effect both production from the turbine, but also the operating costs of the turbine with increased stresses and strains reducing component life. The Cornell Wind Team is preparing for an international experiment at the Canadian Wind Energy site on Prince Edward Island.
