A numerical model of the transfer of a gaseous and dispersed 
impurity in the atmosphere is described. The model is based on the 
semi-empirical stationary equation of turbulent diffusion in the boundary 
layer of the atmosphere with account for the gravitational deposition 
of particles. The altitude profiles of the coefficient of turbulent 
diffusion and of the wind velocity are approximated according to the 
Monin-Obukhov theory and the data obtained by Byzova with her 
coworkers. The atmosphere stratification is determined on the basis 
of standard meteorological data. The model is compared with experimental 
data and with well-known techniques used to calculate the propagation 
of impurity in the atmosphere.
