In meteorology, the ability of radiation of wavelength around 10 μm to escape absorption by the earth's atmosphere. This wavelength nearly coincides with Earth's peak radiation, and allows some of the outflow of terrestrial radiation to be lost to space, thus, in part, upholding the thermal equilibrium of the atmosphere, which is also achieved by convection. See, for example, Gube et al. (1996) J. Climatol. 3, 4.
