Abstract:

A model of a clear standard atmosphere, for determing attenuation in the ultraviolet, the visible, and the infrared windows, is derived. The derivation is based on a Rayleigh atmosphere combined with aerosol and ozone components. The format of the model is a series of tabulations for 22 wavelengths with Rayleigh, aerosol, and ozone components arrayed at kilometer intervals to an altitude of 50 kilometers. Exploratory calculations pertaining to horizontal, vertical, and slant-path transmission from sea level, transmission between two altitudes and transmission to space are readily made from the tabulations. Because of its more extensive coverage and improved computational programming, this report, including the tabulations, fully replaces the earlier publication, A Model of a Clear Standard Atmosphere for Attenuation in the Visible Region and Infrared Windows, by this author.
