| Summary: | This article presents few empirical models to be used prediction of atmospheric attenuation due to airborne suspended particles such as sand, dust, fog and mist. The attenuation can be determined using the proposed models as standard methods considering various types of weather conditions including silicadominant sandstorm, dust storm, fog or mist. As atmospheric attenuation heavily affects the transmission of data using visible light communication, we study the effect of air suspended particles to scattering amplitude and turbulence phase of the light beam. The proposed models are compared with existing attenuation models in the case of attenuation under foggy weather condition. The proposed models especially proposed Model 2 is seen to be best fit for prediction of atmospheric attenuation under dense to very light fog weather.
