Abstract
Absorption coefficient of emission gases of carbon dioxide responsible for temperature in the troposphere layer, which is less than the altitude of 10 km in the atmosphere, is presented in this work. It has been well known that the solar irradiation within short wavelength range near the visible range can be absorbed, scattered and transmitted by the atmosphere and absorbed and reflected by the earth ground. The ground emits radiation in the ranges of long wavelengths. In the presence of carbon dioxide and other emission gases, the atmosphere acting as the glass of a greenhouse increases temperature of the atmosphere. Even though global warming strongly affects the life of the human being, the cause of global warming is still controversial. This work thus establishes a fundamental, systematical and quantitative analysis of absorption coefficient of carbon dioxide in the troposphere layer. Absorptions of carbon dioxide are considered in bands centered at 15, 10.4, 9.4, 4.3, 2.7 and 2 micro meters. The predicted absorptions agree with experimental and theoretical results in exponential wide band model.
