• Resumen

  • 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".
