Electrophotometric Studies of the Luminescence of the Night Sky (Elektrofotometricheskie Issledovaniya Svetimosti Nochnogo Neba)
Abstract
Basic results are given of work performed in the photometry laboratory, from 1948 to the present, making use of electrophotometric methods developed in the laboratory. Diurnal variations of the infrared radiation of the night sky were detected. The energy distribution in the radiation spectrum of the night sky was measured in absolute units. Infrared radiation from the Milky Way was detected. Twilight flashes of radiation from the upper atmosphere in the visible and infrared spectral regions were detected and studied. Diurnal variations were detected in the ultra-violet region of the radiation of the night sky, and the distribution of brightness of the night sky over the firmament was measured. A positive correlation was established between the infrared radiation of the night sky and solar activity. The infrared component of the radiation of the aurora polaris was measured. A general approach is proposed to the mechanism of excitation of the radiation of the night sky. This approach consists of accounting for the scattered short-wave ultraviolet light from the sun. This light is present in the upper layers, by night as well as by day, as a result of processes of anomalous refraction and secondary scattering.
