XXXI. Atmospheric scattering and absorption of ultra-violet sunlight

Abstract

The scattering of a parallel beam of unpolarized sunlight in a plane-stratified atmosphere is considered, taking into account the polarization of scattered light and allowing for the optical anisotropy of the molecules of air. Allowance is also made for the attenuation of the ultra-violet lightdue to absorption by atmospheric ozone. Expressions are derived for the intensities of the primary, secondary, and tertiary scattered light emitted and received in any direction and at any point in the atmosphere.
