The term “greenhouse effect” became part of public lexicon decades ago, thanks to the ongoing discourse on climate change. A natural phenomenon, the greenhouse effect describes how heat from the sun, in the form of radiation, is trapped by gases in the Earth’s atmosphere. But a large amount of radiation is still lost to outer space, because these wavelengths are poorly absorbed by atmospheric gases. These wavelengths constitute long wavelength infrared (LWIR) radiation.
