Assuming that for signs lidar to two frequencies, the extinction reason to backscatter is independent of the position along the range lidar, and that the reason of the extinction coefficients for the two frequencies, is independent of the position along this range, Ackermann, it has used the equations derived by Potter and Kunz, to demonstrate that an unique solution exists for a type of atmospheric aerosol starting from the information contained in two you point out simultaneous lidar to two different wave longitudes. In this article it is reported a computation method used to evaluate the optic thickness, keeping in mind a high relationship sign-noise of the sign lidar starting from experimental data, and with base in the profile of dependent extinction of the range R deduced by Ackermann.
