Abstract:

A technique for retrieval of altitude distribution of post-volcanic stratospheric aerosol optical and microphysical parameters from data of atmospheric remote sensing at the wavelengths 355, 532 and 1064 nm is developed. The retrieval of aerosol backscattering coefficients is performed using robust multiple regressions between aerosol optical characteristics at the wavelengths mentioned above, established on basis of statistical optical-microphysical model of stratospheric aerosol. The solution of inverse problem is based on polynomial multiple regressions between aerosol integral microphysical parameters and spectral values of aerosol backscattering coefficient. The reliability of the established regressions is confirmed by their conformity with the data of independent experimental data. The results of numerical experiments for determining aerosol backscattering coefficient profiles and microphysical parameters are shown for variety conditions in post volcanic stratosphere.
