“…Indeed, it was not until the mid-1990s that interest in the topic was revived, principally due to the re-evaluation of observations from the InfraRed Interferometer Spectrometer (IRIS-D) by Goody and co-workers at CalTech. IRIS-D, on the Nimbus-4 meteorological satellite, measured the Earth's outgoing longwave spectrum from April 1970 to January 1971 [19]. Spanning the range 400-1600 cm −1 (6.25-25 μm) with a nominal spectral resolution of 2.8 cm…”

“…This phenomenon is illustrated in a classic paper 29 that gives the first portrait of the Earth in the thermal infrared from space: despite the fact that CO 2 is nearly uniform in the atmosphere, the 667 cm -1 CO 2 feature is prominent in the tropics, where the thermal gradient between the surface and the upper atmosphere is large (~100 K), but it is hardly detectable in polar observations, where stratospheric and surface temperatures are nearly the same 24 . A simple model of HD189733b infrared emission spectra illustrating this effect is given in Fig.…”
