The method for estimating the turbulent energy dissipation rate from measurements by a conically scanning pulsed coherent Doppler lidar (PCDL), generalized to the case of arbitrary ratios of the average wind velocity to the linear scanning velocity, was tested on the data of atmospheric experiments while the use of a Stream Line PCDL and an sonic anemometer. A comparative analysis of the measurement results with the two devices showed that the improved method, which, unlike the previous approach, takes into account the wind transfer of turbulent inhomogeneities, allows obtaining unbiased estimates of the dissipation rate for any ratio of the average wind speed to the linear scanning speed.
