This paper deals with numerical approach to modeling of atmospheric dispersion of pollutant caused by a point source. The modeling of a pollution in the atmosphere has a long history and has gone throw great improvements over the last century. Two main methods can be distinguished from the modeling point of view: the analytical and the numerical methods. Both methods have their advantages and disadvantages, however, in the latest developments the numerical method has had the major role. Our work has been concerned on modeling pollution in the atmosphere caused by small sources. These sources can be marked as point sources. For the primary validation of our numerical solution, we have used a simple version of the model. The analytical solution of this version can be obtained and may be used for comparison. An intended progress of our work is outlined at the end of the paper.
