Fluctuations of light scattered by fractal clusters

Fluctuations in light scattering from a finite ensemble of fractal clusters are studied numerically and theoretically is shown that, for a wide range of wavelengths and angles, relative fluctuations in the scattered intensity are very close to 1 and do not depend on the number of monomers N in fractal clusters (whereas they are proportional to 1/root N for trivial clusters). The relations describing fluctuations in the light scattering are suggested; they can be used to extract important information about properties and parameters of fractal pollutants in the atmosphere.
