There is a hole in the blanket — or a window, if you will — in the low end of the infrared range (roughly 8-14 μm) that lets in visible light and heat because none of the atmospheric gasses ...

Image Credit: Iridian Spectral Technologies. The wavelength range of the atmospheric window for earth observation is roughly between 300 nm and 15 µm, essentially spanning the visible spectrum and ...

"By coating walls and windows with materials that only radiate or absorb heat in the atmospheric window, we can reduce broadband heat gain from the ground in the summer, and loss in the winter ...
