Abstract

Results of the experimental studies of soot aerosol with the help of land-based, aviation-based, space and satellite techniques, having led to the formulation of the gravito-photophoretic hypothesis to explain the vertical transport and stratification of aerosol in the stratosphere and mesosphere are discussed. Gravito-photophoretic effect allows us to explain the results of soot aerosol studies in the stratosphere, uprise of soot aerosol after pyrocumulus emissions in the stratosphere, results of lidar and space observations of aerosol in the upper stratosphere and mesosphere. Development of the methods for modeling photophoretic phenomena is discussed, from the simplest tasks to elaboration of methods and algorithms of solving Boltzmann equations for aerosol clusters on the basis of Monte Carlo methods. Disputable questions connected with gravito-photophoresis are considered.
