Paper Abstract

Now one of the topical problems of atmospheric optics is the creation of effective methods of radiative transfer calculation in the aerosol-gaseous the earth atmosphere that provides a high speed, accuracy and engineering software. In this work, techniques of calculation and parameterization of molecular absorption characteristics, applied to solving the problem of the narrow-band and broadband laser beam propagation, are described. The analysis of errors of the spectroscopic information is performed and techniques of calculation of errors are described. It is believed that intensities and half-widths of spectral lines have systematic and random errors. Results of simulation of influence of temperature and atmospheric gas concentration variations of molecular absorption coefficients are presented. The method of calculation of mean and mean square deviations of molecular absorption characteristics is presented for the case, in which the limited statistical information about meteorological parameters of the atmosphere is used. The prognostic atmospheric model allowing correct optical characteristics of slant atmospheric paths based on the information about near-surface temperature and humidity of the air is offered.
