Abstract

This chapter deals with the FSO link attenuation measurements at very special (severe) climatic conditions of the mountain Milesovka observatory being appropriate for the research but being not typical one. Therefore, examples of measurements from Prague, Budapest, and Milano are added. Fog attenuation (in combination with cloud) is discussed and Kim formula predicting the fog attenuation from visibility was more or less acknowledged. More accurate results are provided for rain attenuation estimation using the Carbonneau formula. Examples discussing concurrent occurrence of rain, fog, and clouds are analyzed. In the last part, we analyze the attenuation due to atmospheric turbulences concluding that the Rytov formula overestimates the attenuation on one hand, but is in good correlation with the measured attenuation on the second hand.
