Based on different cloud models considered, paper gives a statistical estimate of optical wave attenuation. Using the results obtained, a model of a cloudy atmosphere is introduced and a method is proposed to calculate the probability that a given attenuation is not exceeded at any location within the USSR in any month. It is shown that this probability is considerably increased when diversity reception is employed.
