Estimation of the Turbulence Intensity from Lidar Data


A way of estimating the intensity of the structure characteristic of fluctuations of the refractive index \(C_{n}^{2}\) based on data from a two-channel turbulent aerosol lidar operating on the backscatter enhancement (BSE) effect is shown. It is proposed to use V.V. Vorob’ev’s approximation which, for the case of homogeneous turbulence, determines the dependence of \(C_{n}^{2}\) on the ratio of echo signals. This technique is based on experimental data which suggest that the BSE effect appears in a relatively small region of the space near the scattering volume. Results of sounding for a horizontal path are presented.
