Turbine wakes
captured using arc scanning pattern.
A
single Galion can scan over a large area, enabling coverage of many
wind turbines. The velocity field data below-right is a plan view of
multiple turbines and shows the wake trail coming from them.
Above
right. One arc scan across an active wind farm. The red area is
a blade strike from a turbine, and shows how the wake from another
turbine upwind, is feeding directly into it.
Left. A 30 minute average of
many arc scans. This shows a single turbine wake and the effect that
the turbine has
on the ambient wind flow.
Note: The background wind speed
values have been corrected to
remove the effect of the LiDAR observation angle.
Complex terrain:
Wind flow reversal at
tree line.

The Galion was deployed in a shallow valley that was in the lee of a ridge of trees.
The data and illustration below show the flow reversal captured by the lidar.
Right. One of the arc scan
data files plotted up. Wind speed along the line of sight is
colourised - red for flow towards, and blue for away.
