Abstract:

A method has been developed for determining the turbulent energy dissipation rate, the dispersion of the radial velocity and the integral scale of turbulence from the spectral density of the vertical wind velocity measured by a pulsed coherent Doppler lidar. To obtain unbiased estimates of these wind turbulence parameters, the averaging of the radial velocity over the probed volume is taken into account. The method has been tested in a numerical experiment. An algorithm is proposed for calculating the error of the lidar estimates of the dissipation rate obtained by this method.
