We propose here an economical and stable method to determine coordinates of an instant point-like source of aerosol pollution and an amount of emitted pollutants from values of integral pollutant concentration measured at several spatial points. The method is based on solution of a conjugate equation of turbulent diffusion. Two examples are considered. In the first one, a pollutant spreads over a homogeneous underlying surface. The second case is pollutant spreading over the city of Novosibirsk with its real terrain, housing system, green and water areas. Calculations over the area with homogeneous underlying surface give good results already for two reference points, at which the integral pollutant concentration is measured. When simulating the spread over the real terrain, estimates are less accurate, but still quite satisfactory for practical applications of the proposed method.
