Abstract:

The results of numerical study of accuracy of the method of azimuthal structure function for estimation of the dissipation rate of kinetic energy of turbulence from measurements by low energy coherent Doppler lidars are presented. Conical scanning of probing beam of a lidar around the vertical axis is considered. Applicability of the azimuthal structure function method depending on turbulence strength and signal-to-noise ratio is analyzed.

Keywords:

dissipation rate, Doppler lidar, simulation, turbulence strength, signal-to-noise ratio
