Implications of the Equation of Transfer within the Visible and Infrared Spectrum

Abstract

The equation of transfer for radiance, irradiance and scalar irradiance is fully defined and integrated for a scattering, absorbing and emitting medium. Some of the special characteristics of the solar almucantar are delineated as well as methods presented for using the solar almucantar sky radiance in the sky radiance photometer. Measurements made with Visibility Laboratory integrating nephelometer are reviewed and compared to the Barteneva (1960) catalog of photopic volume scattering functions. An average volume scattering function is derived and methods developed for obtaining: 1) the single scattering albedo from horizon sky radiance, 2) the scattering transmittance from sky radiance ratios, and 3) the aerosol optical thickness from solar almucantar radiances.
