New parametrization of aerosol optical properties for inverse atmospheric problems

The statistical approach to modeling of th atmospheric aerosol optical characteristics is presented. This approach bases on an applying (a) different recent models of ail atmospheric aerosol, (b) modeling the variability of the aerosol optical properties by the Monte-Carlo method, (c) calculations of the covariance of the optical aerosol characteristics, (d) expansion of the aerosol optical characteristic variation on the basis of the covariance matrix eigenvectors. Examples of constructing the statistical models of vertical profiles of the extinction coefficient of the stratospheric aerosol are presented. These models take into account aerosol composition (5 different kinds of particles) and different correlations (between aerosol microphysical and atmospheric parameters). The results of the accuracy estimation of the different parameterization methods through the numerical experiments are given.
