We present here the Eulerian model of the vertically averaged sulfur dioxide stationary transfer over Europe. This model is based on numerical solution of the transfer equation of (balance) atmospheric pollutants. We have obtained the "climatic" stationary concentrations of sulfur dioxide in air over Europe for different seasons assuming the process to be stationary. In so doing, we used the climatic data and considered the advective transfer processes, the vortex turbulent diffusion, and dry and humid reconstruction. The chemistry is presented in a simplified form. To create the numerical algorithm we used the finite-difference approximation.
