We will place a sophisticated Doppler LiDAR ~400m downwind to measure the wake and turbulence that arrays of Wind Harvesters create. The purpose of the LiDAR is to evaluate the following:

• How far downwind it is before the wind speed returns to normal.
• What happens to the wind speed and turbulence above the arrays, and how far downwind the effect lasts.

The LiDAR can efficiently and rapidly collect this data in different wind conditions. Modelers then use that data to validate their algorithms and predictions. The predictions are for how much Wind Harvesters increase wind speeds for the taller turbines based on the height of the tall turbines’ towers and the size of their rotors, topographies, and other factors.
