Paper Abstract

A new microphysical model of the photophoretic motion of soot aggregates takes into account their fractal structure has been developed and tested. The calculations and analysis of the motion characteristics of fractal-like soot aggregates in the field of atmospheric radiation have been carried out. The optimal parameters of fractal-like particles were selected, which make it possible to most accurately describe the behavior of soot aggregates in the atmosphere. It has been demonstrated that photophoretic effects for a soot aerosol in a stationary atmosphere are most pronounced in the stratosphere.
