In order to understand the mechanism of greenhouse effect, we developed experimental materials that enables the visual confirmation of the greenhouse effect of gases. It is possible to learn that the absorption wavelength bands of carbon dioxide and methane do not overlap, and about the infrared energy budget (incident = absorption + transmission).
