Institute of Atmospheric Physics measures atmospheric attenuation on experimental FSO link on 850 and 1550 nm for more than one year. Experimental site is located at meteorological observatory on the isolated mountain with frequent fog, low clouds and strong wind occurrence.  Measured attenuation is correlated with the wind turbulence intensity, visibility and LWC. . The paper shows also basic statistical behavior of the long-term FSO signal level in extreme conditions.
