THE STRATOSPHERIC SOLAR AUREOLE

Abstract

The theory of light scattering by small particles is summarized to develop the formulae needed to interpret solar aureole data obtained in balloon flights at stratospheric altitudes. Included are the Rayleihg law for small particles, the Chandrasekhar solution of the planetary scattering problem, and the Mie theory for large particle scattering. Observations cover the wavelength range from 0.37 to 0.79 micron at the scattering angle 2.4 degrees, and over the altitude range from 42,000 ft. to 80,000 ft. The findings suggest that the form of the particle size distribution chang s with altitude, becoming a steeper function of particle radius at higher altitudes. (Author)
