A mathematical model has been developed for studying and predicting the process of transport and diffusion of harmful substances in the surface layer of the atmosphere. The model is based on the fundamental laws of fluid mechanics (conservation of mass, momentum, and energy) and utilizes a conservative numerical algorithm. In addition to meteorological factors, the model takes into account the phenomenon of aerosol particle absorption and capture by vegetative elements, interactions with the Earth’s surface, variation of turbulence coefficient with altitude, and temporal changes in wind direction. In the study, the sources of pollutants are point sources, the intensities of which vary over time. The solution algorithm is based on the method of lines and a finite-difference semi-implicit scheme, ensuring high accuracy in both time and spatial variables. Both upwind and downwind differencing schemes are employed depending on the flow value.
