Abstract
A method for retrieval of the profiles of atmospheric aerosol backscattering coefficients βa along horizontal and inclined paths from the results of three-wavelength probing by laser location systems based on a Nd: YAG laser is proposed. The method uses a power dependence between the spectral values of βa and includes spectral nephelometric measurements of the scattering coefficients by an angle of 33°, which characterize the relative spectral dependence of aerosol extinction. The sensitivity of this method to spatial variations in the above coefficients, to the deviation of βa from the dependence used, and to errors in calibration and measurement of signals is studied. The method is demonstrated to be stable both upon using the absolute calibration of the lidar and at an arbitrary position of the reference point.
