Abstract: The paper considers the urgent task related to monitoring and forecasting the ecological state of the surface layer of the atmosphere in industrial regions with the aim of maintaining a balance of the sanitary norm. The review of scientific works on the development of mathematical models, numerical methods and their software for carrying out a complex study of transport processes, diffusion and transport of aerosol particles and exhaust gases in the atmosphere is reviewed. The developed mathematical model of the process of transport and diffusion of aerosol particles in the atmosphere is considered, which takes into account the essential parameters of the research object: the velocity of the particles of aerosol emissions in the atmosphere, which depends on the mass and radius of the particles; acceleration of free falling of particles; coefficient of the drag of particles during their transfer by air mass; body shape factor for calculating the drag force; air flow lift; the density of particles and air, as well as the viscosity of air.
Key words: mathematical model, transport, diffusion, harmful substances, weather and climate factors, hydromechanics, fine particles.
