“…The atmospheric conditions affect the reliability and availability of FSO Links. Atmosphere contains fog, rain, smoke, smog and other atmospheric particulates which often alter the propagation of signal through it [13][14]. Out of all these atmospheric conditions, fog is the major challenge for FSO communication links which sometime almost reduce the availability to 0% [2].…”

“…An integrated Water Vapor (IWV) model based on GPS observations has been used in climatology along with the numerical weather prediction (NWP) model [63]. The GPS IWV model is also applied as a new approach to fog detection and assessments by studying (in time domain) the relationship between the GPS IWV and meteorological observations during formation, evolution, and dissipation of dense fog [64,65].…”

This work presents a selective overview of natural fogs in terms of fog types, forms and states of occurrence, physical, micro-physical, chemical and dynamic properties, basic characterizing parameters, etc. In focus are related achievements and contributions reported mainly during the last decade and a half, as a result of both laboratory studies and field observations. Processes of homogeneous and heterogeneous nucleation are analyzed in the aspects of condensation, nuclei diversity and specifics, as related to the activation, growth and deposition of fog droplets. The effect is highlighted of the water vapor's partial pressure on the surface tension of the liquid water-air interface and the freezing point of the water droplets. Some problems and aspects of fog modeling, parameterization, and forecasting are outlined and discussed on the examples of newly developed relevant 1D/3D theoretical models. Important issues of fog impacts on the air quality, ecosystems, water basins, societal life, and human health are also addressed and discussed, particularly in cases of anthropogenically modified (chemical, radioactive, etc.) fogs. In view of reducing the possible negative effects of fogs, conclusions are drawn concerning the new demands and challenges to fog characterization imposed by the changing natural and social environment and the needs for new data on and approaches to more adequate observations of fog-related events.

“…Most of the literature work in FSO channel modeling considers fog as the harshest environment for FSO systems. This is because such work was performed in foggy environment in Europe and North America [5]. In this work, we compare the effect of fog and dust on the FSO links and determine which one has more effect.…”

“…The primary challenge in outdoor FSO systems is weather condition represented by signal attenuation [5]. This attenuation ranges from less than one dB/km in clear weather to hundreds of dBs/km in harsh weather.…”
