For the first time in Ukraine, on the basis of the experimental data of the annual cycle of radiometric observations of the thermal radiation of the atmosphere at a frequency of 39 GHz, micro-climate-based estimates of the probabilities of communication failure on inclined terrestrial-space lines have been made. The cumulative distribution functions of atmospheric attenuation, analyzed in the work, make it possible to give a reasonable quantitative estimate of the probability and duration of interruptions in the operation of EHF communication due to meteorological conditions for the first time for one of the regions of Ukraine. The data obtained can be used in other regions with similar climatic regimes.
