Visual Observations and Spectral Investigations of the Earth's Atmosphere Twilight Aureole from the Soyuz-5 Spacecraft.
Results are given of the spectrophotometric measurements of the earth's atmosphere twilight aureole as first performed from the Soyuz-5 spacecraft. The analysis is made of the experimental findings depending on the wavelength, the perigee height of the sight ray above the earth's surface, the sunset angle, etc.. The comparison is carried out of the vertical profiles for the twilight aureole monochromatic brightness with the results of the corresponding theoretical calculations for the aerosol Elterman model (1968). The color diagram and pictures of the twilight aureole are built using theoretical values of the brightness aureole for different terrestrial atmospheric models and employing the experimental data and the results of visual observations from the Soyuz-5 spacecraft.
