Abstract

Multiple scattering effects in droplet aerosols were investigated theoretically using three different numerical approaches and experimentally by means of a specially developed measuring system. The system allows quantitative determination of laser light extinction and scattering. Measurements were performed in scale model clouds formed by growing water droplets. This was accomplished in an expansion cloud chamber under well-controlled laboratory conditions. In many cases however, the investigated models and the experimental evidence showed substantial discrepancies depending on parameters and ranges of variables within which a model was used. The work is in progress and preliminary experimental results are discussed and compared with computations. Based on the experimental conditions chosen in this study, an attempt was made to explain the accuracy of the applied models to describe multiple scattering effects in aerosols.
