We present a method of estimation of atmospheric turbulence characteristics from the transversal structure function of velocity measured with a scanning (in vertical plane) pulsed coherent lidar. The altitude turbulence profiles are reconstructed from data of measurements of wind velocity by 2-µm lidar with use of the developed method of transversal structure function and the method of turbulence estimation from width of the Doppler spectrum. It is shown that, for conditions of moderate to strong turbulence, the methods give close results.
