On the Intensities and Altitudes of the Night-Sky Light

Abstract

Taking into consideration of the atomospheric extinction, refraction, and scattering, the formulae for the received intensities of the night-sky light into a solid angle was introduced geometrically, where the luminescent layer assumes a geoconcentrics pherical surface of the uniform radiant intensity, An attempt was made to evaluate the height of the layer from the observed data with the aid of these formulae. Finally, discussing the general assumptions, the authors propose possible geographic distributions of the radiant intensities and the simultaneous observation to which the for mulae are applicable.
