The water coating of the smoke soles, which takes place in the humid atmosphere, is one of the main factors reducing the precision of the lidar measurements of smoke plumes. The current paper presents the results of theoretical investigations of the process of water shell growth on the smoke particles. These investigations were conducted on the basis of a Gaussian model of smoke plumes (that takes into account the sedimentation of the coated particles during the plume diffusion) at various meteorological conditions and plume parameters. The numerical calculations show that when the plume is initially very humid, a zone with supersaturated water vapor and extremely high moistening of the particles appears near the smoke source. The process of water coating is essentially influenced also by the seasonal and diurnal variations of the temperature and humidity in the surface layer of the atmosphere. The degree of water coating of the particles is established to be maximal in winter at night and slow wind. The paper also presents some calculation of the optical properties of smoke particles.
