Abstract
A method is proposed for determining the parameters of wind turbulence from data measured by a conically scanning pulsed coherent Doppler lidar in conditions of a weak echo signal. The results of spatiotemporal visualization of the kinetic energy of turbulence, its dissipation rate, and integral scale of turbulence from measurements by the Windcube 200s lidar in the atmospheric boundary layer are presented. It is shown that the applied lidar data filtering procedure allows acceptable results with a nonzero probability of a bad estimate of the radial velocity.
