A method for determining the coordinates and power of a point source of pollution from the values of pollutant concentration measured at several points is considered. The method is based on the equation conjugate with the semiempirical equation of turbulent diffusion. The capabilities of the method are studied for the case of the presence of both measurement errors and statistical scatter due to the atmospheric turbulence in measurements. Two series of computations have been performed. In the first series, we used concentrations obtained by numerical simulation of aerosol spreading over Novosibirsk. Actual experimental data were used in the second series. The obtained results on reconstruction of the source's coordinates and power can be considered quite good.
