Wind field reconstruction from nacelle-mounted lidar short-range measurements [PDF]
Profiling nacelle lidars probe the wind at several heights and several distances upstream of the rotor. The development of such lidar systems is relatively recent, and it is still unclear how to condense the lidar raw measurements into useful wind ...

A six-beam method to measure turbulence statistics using ground-based wind lidars [PDF]
A so-called six-beam method is proposed to measure atmospheric turbulence using a ground-based wind lidar. This method requires measurement of the radial velocity variances at five equally spaced azimuth angles on the base of a scanning cone and one ...
