TLDR
In this article, a quantitative experiment which illustrates the absorption by carbon dioxide of infrared light radiated from the earth is described, based on a model derived from Beer's Law; the experiment shows that, theoretically, 99% of the infrared light in the range from 2390 to 2275 cm-1 radiated by the earth was absorbed in the lowest 25 m of the atmosphere.Abstract:
A quantitative experiment which illustrates the absorption by carbon dioxide of infrared light radiated from the earth is described. The experiment is based on a model derived from Beer's Law; the experiment shows that, theoretically, 99% of infrared light in the range from 2390 to 2275 cm-1 radiated from the earth is absorbed in the lowest 25 m of the atmosphere. The experiment should be useful for quantitatively describing the "greenhouse effect".read more

Photoacoustic Experimental System To Confirm Infrared Absorption Due to Greenhouse Gases.
TL;DR: It can be shown that there is a significant difference in IR absorption between GHGs and the major components of the atmosphere, N2, O2, and Ar, which helps students understand that the minor components, that is, the GHGs, determine the IR absorptivity of the Atmosphere.
