摘要

A measurement procedure is proposed to retrieve the profiles of atmospheric aerosol backscatter coefficients (Pa) from the results of multi-wavelength sounding of the atmosphere by a laser location system based on a Nd:YAG-laser. The procedure uses a regression dependence between spectral values of β{sub}a (background aerosol model) and involves the determination of coefficients which characterize the relative spectral behavior of aerosol extinction. The stability of the procedure to spatial variations of the above coefficients, a deviation of β{sub}a from the dependence used, and calibration and measurement errors is examined. This procedure is compared with the widely used Fernald method by means of a numeric experiment. This procedure is demonstrated to be effective for retrieving vertical profiles of β{sub}a in the troposphere, especially in the short-wavelength region.
