Abstract

Abstract The paper proposes the method for estimating the turbulence energy dissipation rate and the variance of the vertical component of the wind velocity vector from the spectral density of radial velocity measured by a pulsed coherent Doppler lidar. The method takes into account the averaging of the radial velocity over the probing volume. It is shown that neglecting the spatial averaging leads to the understating the dissipation rate.
