Abstract
The absorption coefficient of carbon dioxide is 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 can penetrate through the troposphere layer within short wavelength range near the visible range. It can be absorbed, scattered 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 layer 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 across the troposphere layer. Absorption coefficient is a function of wavelength, temperature and concentration. Carbon dioxide is absorbed in long wavelength bands centered at 15, 10.4, 9.4, 4.3, 2.7 and 2.0 micrometers, respectively. The predict absorption coefficients agree with experimental and theoretical results in the exponential wide band model in different bands. The computed results are confirmed by experimental data, revealing the effects of carbon dioxide on temperatures in the troposphere.
