what does this “100-200 meters” refer to?
Does it refer to “100-200m above the ground” or “100-200 in the front”?
———————–
The device measured wind movement at 40, 60, 80, and 100 metres above the ground, and 100-200 metres in front of the turbine.
=============
more context:
Dr Mikkelsen and his colleagues worked out that they could use lidar to scan incoming wind and determine how it was behaving before it struck the turbine. To try this idea out, they first placed lidar devices at the base of 120-metre-tall wind turbines at Hovsore, the Danish test site for such devices. The device measured wind movement at 40, 60, 80, and 100 metres above the ground, and 100-200 metres in front of the turbine. The data it collected were then compared with wind measurements taken by cup anemometers in order to calibrate the lidar. That done, the computer which analyses the lidar data could be connected to the motors that adjust the pitch of the turbine blades, in order to maximise energy production and reduce damage.
I read it as measurements taken at 8 locations, 100 metres in front of the turbine at heights of 40, 60, 80 and 100m, and 200 metres in front of the turbine at the same 4 heights.
