“…1). In previous works 20, [34][35] we confirmed the relevance of the western Mediterranean coastal aerosol model 21 The Negev is a barren desert area between the Mediterranean, Red, and Dead Seas. The north Negev region located on the north to northwestern portion of the Negev Mountains includes areas from the Mediterranean coast to Beer Sheva.…”

“…2 and 3 is an example of the transition from marine to continental aerosols when the air mass is advected over the land, similar to observations in other coastal locations [19][20][21][34][35] . For short fetches [34][35] , the land-origin particles prevail in the submicron range and their concentrations increase with decreasing wind speeds due to accumulation effects caused by slower dispersion. The influence of fetch on the marine aerosol concentrations for coastal zones is well described 3,19 , where the concentrations of aerosols in the atmosphere vary with wind speed 4 :…”

“…3. In fact, based on our previous works 20, [34][35] , it was found that the concentration of coarse particles (larger than 1 µm), which at longer fetch consisted mainly of sea-salt particles, increases with increasing fetch. In addition, the concentration of coarse particles increases with wind speed because of increasing wind-derived sea salt droplets at the surface.…”

“…Figure 6 shows simple comparison between our experimental/model curves and curves based on the Table 2 models. 20,35 This figure shows differences over the range 0.2 to 40 [µm] of aerosol particles. Our curves exhibit lower concentration relative to Urban and Rural aerosol models, but higher relative to Continental aerosol model.…”

Various experiments have been carried out recently in Middle East desert regions for prediction of aerosol particle concentration and size distribution. The differences between urban and non-urban desert coastal environments, and urban and non-urban desert continental environments, are of interest. During these experiments aerosol particle concentrations for similar weather but different environmental conditions were measured and analyzed. The well-known MODTRAN urban, desert, maritime, and continental aerosol models were tested for aerosol particle distribution prediction. Unfortunately, many of those models did not predict correctly the aerosol distributions in different types of arid environments. Comparison of results leads to the following interesting conclusions: the aerosol distribution for each of our environments, such as urban-coastal-desert, non-urban-coastal-desert, urban-continental-desert, and non-urbancontinental-desert, can be predicted by multiplying the Mediterranean coastal aerosol model parameters with semiempirical correction functions or factors. The functions are different for coastal and continental environments, and for urban and non-urban environments. The models proposed in this work better describe effects of different atmospheric conditions for Middle East desert aerosol modeling.
