An Empirical Model for Atmospheric Transmission in the Mid Infrared Spectral Region

Abstract

Taylor and Yates have measured atmospheric absorption in the infrared over long horizontal paths. They published thirteen spectra which covered four path lengths from 0.3 to 27.7 kilometers and seven water vapor concentrations from 0.10 to 2.3 pr cm/km. This report describes a method to fit their spectra to a model in the 3- to 5-micrometer interval. With this method, particulate scattering coefficients, band parameters of the Goody model for H2O absorption and band parameters for the combined absorption of all other molecular species were extracted.
