Abstract
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. This work proposes a new model for urban aerosol size distribution prediction based on an extensive series of measurements. The model introduces coefficients and characteristics of processes of absorption and scattering by aerosol particles in the urban inhomogeneous region for semi-arid and 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. It is shown that, in Middle East urban regions, larger differences in aerosol particle concentration are observed. Effects of different atmospheric conditions for urban aerosol modeling are better described by the model proposed in this work using parameters obtained empirically.
