Abstract
Possibility of determination of the turbulent energy dissipation rate from data measured by a 1.5-μm pulsed coherent Doppler lidar using the conical scanning of the probing beam under different atmospheric conditions has been studied experimentally. It is shown that from array of the radial velocities measured by this lidar in the atmospheric surface layer during 5 min one can estimate the dissipation rate with the relative error 20-30% under conditions of moderate and strong wind turbulence.
