Malm, in Visibility, 2016 Atmospheric Extinction Coefficient. The atmospheric extinction coefficient (b ext), which is the sum of scattering and absorption by particles and gases, is a measure of the alteration of radiant energy as it passes through the atmosphere.It is discussed in some detail in Chapter 2.The effect of the atmosphere on …
WebIn astronomy, extinction is the absorption and scattering of electromagnetic radiation by dust and gas between an emitting astronomical object and the observer. Interstellar extinction was first documented as such in 1930 by Robert Julius Trumpler. [1] [2] However, its effects had been noted in 1847 by Friedrich Georg Wilhelm von Struve, [3 ...
