Abstract

A method has been developed for estimating the turbulent energy dissipation rate and the variance of the radial velocity from the spectral density of the vertical wind velocity measured by a pulsed coherent Doppler lidar (PCDL). To obtain unbiased estimates of such wind turbulence parameters, the averaging of the radial velocity over the probed volume is taken into account. The method was tested in a numerical experiment, as well as in an experiment on the territory of the Basic Experimental Observatory of the IAO SB RAS using the Stream Line PCDL.
