The specific results of a propagation study carried out on a free space optical link working at 850 nm on an 853 m long terrestrial path over a 4-year period from August 2004 to July 2008 are presented. Fog attenuation events were analyzed in detail and were subdivided into the attenuation events due to fog only, and to combinations of fog with rain, fog with snow, and fog with rain and snow, respectively. It is shown that not only attenuation due to fog only but also attenuation due to fog combined with other hydrometeors may have a significant impact on the attenuation of the optical beam.
