LLLJP Lidars

Why lidars? Lidar measurements of the wind flow obtained with high temporal and spatial resolution up to several hundred meters above the surface can provide information to:

• Estimate wind-resource and improve the accuracy of turbine output predictions
• Investigate wind-speed and turbulence conditions within the atmospheric layer occupied by turbine rotors.
• Study nighttime behavior and evolution of the low-level jet (LLJ), a major source of wind power in the Great Plains
• Investigate complex terrain effects - speedup of flow over hills; channeling by valleys, canyons, and gaps
• Understand and estimate wake effects by scanning wind field behind the turbine at a downstream distance of 2D
• Improve representation of wind and turbulence processes in NWP models
