Abstract : Horizontal visibility of the atmospheric layer near the ground is subject to daily and yearly fluctuations. The author utilized visibility data from geographic points with widely differing climatic conditions: Alma-Ata, Kiev, Batumi, Karadag, Tashkent, Sverdlovsk, Murmansk, Vladivostok, Petropavlovsk-Kamchatskiy, and Yuzhno-Kuril'sk. The fluctuations of visibility in all the locations were similar, the highest visibility being in the summer months. The relative humidity curves show the same trend. Daily visibility varied in a similar manner, the highest visibility being in the morning.
