Abstract:

Visible spectra, Infrared spectra, Atmospheric refraction, New Mexico Atmospheric attenuation A method developed by previous workers for measuring the absorption coefficient of strongly absorbing powdered materials has been applied to samples of atmospheric dust in the 0.3 to 1.1 micrometers wavelength interval. This work, which is based on the Kubelke-Munk theory of diffuse reflectance, provides an estimate of the optical absorption coefficient. The corresponding imaginary refractive index is calculated from this value. Results are given for several samples of dry atmospheric dust collected in the desert of southern New Mexico.
