Abstract

A new band model was established in this paper. Co₂ CO, H₂O and CH₄ are the main infrared absorption gases in atmosphere. The infrared spectral absorption coefficient of the gases can be expressed in a simple function with the new band model, and the expression can be used to calculate directly. In a certain wavelength range, the mean absorptance and transmittance of the gases were calculated with the new band model, the error was in reasonable precision range by compared with experimental data.
