摘要：
The software package for calculation of optical and microphysical parameters and motion characteristics of aerosol particles in the stratosphere in the field of atmospheric radiation, temperature and wind was developed. Specialized aerosol solver include various parts for calculating the optical and thermal characteristics of the particles: unit for calculation of atmospheric radiation field (incident shortwave and outgoing thermal radiation); unit for the wind field calculation for the standard atmospheric models; unit for calculation of particle motion characteristics for different altitudes in stratosphere and mesosphere. The microphysical model of photophoretic motion of soot aggregates taking into account them fractal structure is presented. Comparison with known experimental data is executed, and good qualitative and quantitative agreement is revealed.
