Various experiments have been carried out recently in the Middle East urban (Beer Sheva, Israel) environment for prediction of aerosol particle concentration and size distribution. During these experiments aerosol particle concentrations for different weather conditions were measured and analyzed. New aerosol size distributions are described in this work, based on an extensive series of measurements. This measurement data show the processes of absorption and scattering by aerosol particles in urban inhomogeneous areas for rainy atmospheric conditions. Several parts of the results are compared with those obtained through measurements in different geographic and climatic environments, as well as with different aerosol distribution models. Effects of different atmospheric conditions during rain on aerosol modeling are better described in this work.
