“…Effects of aerosols and refractivity on transmission in the coastal environment have been analyzed based on field experiments along the Californian coast. 2 The results show that refractive effects are the primary parameter influencing near-surface propagation, while aerosols can also have a very large effect in this coastal region. 3 The electro-optical propagation codes IRBLEM 4 and EOSTAR 5 aim at a description of these effects by including both refraction and extinction due to gases and aerosols for the marine environment.…”

Abstract. The performance of electro-optical systems can be substantially affected by aerosol particles that scatter and absorb electromagnetic radiation. The model that is most frequently used for the prediction of aerosols and their effect on extinction in the marine atmosphere is the US Navy Aerosol Model (NAM). However, NAM can be significantly less reliable in coastal areas than on the open ocean. Based on an extensive series of measurements conducted on the island of Inisheer (Irish West Coast), an empirical aerosol model for the coastal zone formulated as an extension of NAM, in which coastal effects are modeled as a function of fetch, has been developed. This work is extended to the Mediterranean using an aerosol dataset recorded on the island of Porquerolles in the Bay of Toulon (France) and has been coupled with the Mie theory to give a code for the extinction, the code MEDiterranean EXtinction (MEDEX).

“…However they are inadequate for representing their effects in coastal zones, because they do not account for specific processes unique to the region [9][10][11] . Clouds and coastal aerosols, i.e., continental and surf generated aerosols, can greatly affect the performance of airborne forward looking infrared, search, and track systems operating within the coastal zone [12][13][14][15] . Other parameters that must be considered include the contrast between the target and its background, the path radiance, refraction, turbulence, and molecular effects.…”

Influence of sea-breeze winds on aerosol particle concentration and size distribution for up to 50-km overland distances in the Middle East

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.

Recently several investigators proposed an extension of the Navy Aerosol Model (NAM) based on analysis of an extensive series of measurements at the Irish Atlantic Coast and at the French Mediterranean Coast. This work extends NAM by use of a similar analysis using 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. Results of the aerosol size distribution are compared with those obtained through measurements carried out over the Atlantic Ocean and Mediterranean Coasts. An analysis of these different results allows a better understanding of the similarities and differences between different coastal and open ocean zones. Parameterization is introduced. The aerosol particle concentrations and their dependences on wind speed for these coastal zones are analyzed and discussed.
