Book Description
Atmospheric extinction in the ultraviolet is considered spectrally and with altitude as follows: (1) The Rayleigh scattering coefficients are determined by utilizing spectral scattering cross sections with molecular number densities from the U.S. Standard Atmosphere; (2) The aerosol attenuation coefficients are established from available transmission measurements in conjunction with a suitable aerosol density distribution. (3) The atmospheric ozone absorption coefficients result from Vigroux's coefficients applied to a generalized ozone distribution. The resulting coefficients and computed optical thickness values are placed in the format of a series of tabulations for wavelengths from 0.27 to 0.55 microns, with the parameters arrayed at kilometer intervals to an altitude of 50 kilometers. The tabulations presented permit various exploratory calculations including horizontal, vertical, and slant-path transmission from sea level and from space into the atmosphere; also, between any two desired altitudes within the occluding ozone region.

Book Description
An atmospheric attenuation model for the ultraviolet, visible, and infrared was developed in 1964, based on scattering (molecules and aerosols) and ozone absorption. Since then more measurements have been made and our knowledge of aerosol attenuation has widened. These circumstances result in attenuation model changes which are relatively unimportant for most exploratory calculations. In this paper the optical parameters are computed spectrally and with altitude as follows: (1) pure air attenuation parameters are determined by utilizing Rayleigh scattering cross sections with molecular number densities from the standard atmosphere; (2) ozone absorption parameters are derived based on Vigroux's coefficients applied to a representative atmospheric ozone distribution; (3) seven sets of aerosol measurements are compared and a profile of aerosol attenuation coefficients vs altitude is developed. Attenuation coefficients and optical thickness due to molecular, aerosol, and ozone attenuation are computed and tabulated individually so that the influence of each can be compared. The newly derived tabulations permit various exploratory calculations, including horizontal, vertical, and slat-path transmission at kilometer intervals to an altitude of 50 km, individually for each attenuating component or for overall atmospheric extinction (molecular + ozone + aerosol).
