Two measuring systems using lasers with wavelengths of 633 nm and 670 nm anddifferent measuring geometries were used to investigate the same droplet cloud yielding two independent particle concentration measurements. Measurements were performed in such a way that multiple scattering was significant only in one of the measuring systems allowing the determination of the magnitude of multiple scattering effects in a given droplet aerosol. Numerical computations of multiple scattering were performed using a solution of the radiative transfer equation in the small angle approximation. Experimental results are in good agreement with the theoretical data for optically thin aerosols. For larger optical depths the experimental results indicate less attenuation then predicted by the above mentioned theoretical description, however good agreement of this data was found with an expression for radiation transmission through a cloud of scatterers based on Monte Carlo simulations.
