Abstract: Recently, an extension of the Navy Aerosol Model NAM was proposed based on analysis of an extensive series of measurements at the Irish Atlantic Coast and at the French Mediterranean Coast. We con- firm the relevance of that work for the distant eastern Meditteranean and extend several coefficients of that coastal model, proposed by Piazzola et al. for the Meditteranean Coast a form of the Navy Aerosol Model ,t o midland Middle East coastal environments. This analysis is based on data collected at three different Middle East coastal areas: the Negev Desert Eilat Red Sea Coast, the Sea of Galilee Tiberias Coast, and the Mediterranean Haifa Coast. Aerosol size distributions are com- pared with those obtained through measurements carried out over the Atlantic, Pacific, and Indian Ocean Coasts, and Mediterranean, and Bal- tic Seas Coasts. An analysis of these different results allows better un- derstanding of the similarities and differences between different coastal lake, sea, and open ocean zones. It is shown that in the coastal regions in Israel, compared to open ocean and other sea zones, larger differ- ences in aerosol particle concentration are observed. The aerosol par- ticle concentrations and their dependences on wind speed for these coastal zones are analyzed and discussed. We propose to classify the aerosol distribution models to either: 1. a coastal model with marine aerosol domination; 2. a coastal model with continental aerosol domina- tion referred to as midland coast in this work; or 3. a coastal model with balanced marine and continental conditions. © 2005 Society of Photo-Optical

TL;DR: In this article, a Middle East model of refractive turbulence strength (C n 2 ) vertical profile has been developed on the basis of a large set of imaging LIDAR measurements.
Abstract: The estimation of the performance of electro-optical systems depends on the accuracy of the atmospheric models being used in the propagation prediction codes. On the basis of a large set of imaging LIDAR measurements a Middle East model of refractive turbulence strength (C n 2 ) vertical profile has been developed. The model is presented in this work. Implications can be important for optical communication, laser weaponry, imaging through the atmosphere, and adaptive optics.

TL;DR: In this article, the authors proposed a new model for aerosol size distribution prediction up to 50 km distance away from the Mediterranean coast based on an extensive series of measurements and introduced coefficients and characteristics of processes of absorption and scattering by aerosol particles in the northern Negev desert areas.
Abstract: Various experiments have been carried out recently in Middle East (Israel) environments for prediction of aerosol particle concentration and size distribution versus sea-breeze wind speeds and overland ranges. During these experiments aerosol particle concentrations for different overland distances were measured and analyzed. This work proposes a new model for aerosol size distribution prediction up to 50-km distance away from the Mediterranean coast based on an extensive series of measurements. The model introduces coefficients and characteristics of processes of absorption and scattering by aerosol particles in the northern Negev desert areas. Effects of sea breeze wind over different ranges are described by the model proposed in this work using parameters obtained empirically.
