The effect of atmospheric aerosol on the radiation cooling through far infrared window

This paper aimed at reducing emissions of CO₂, discussed issues about the theory of radiation cooling. We can use the upper atmosphere or outer space as a cold source because of their low temperature, and it will promote the heat transfer by radiation through the 8~13 μm atmospheric infrared window to reduce energy consumption and CO₂ emissions. In quantitative analysis, the radiative properties of atmospheric gases and aerosol particles play a decisive role in the heat transfer process. In this paper, the model of the attenuation, which caused by aerosol particle scattering and absorption when 0.2-20 μm band of electromagnetic waves were passing through the atmosphere, was established and calculated with Mie theory. Ultimately, the result explained the critical role of 8~13 μm atmospheric far-infrared window in the radiation cooling. The paper also did some related theoretical analysis about the application on CO₂ emission reductions.
