Borrowed to learn about the upper atmosphere; the book focuses on the suborbital atmosphere, mostly the troposphere and stratosphere below 100 km.  Chapter 1 shows density and composition graphs up to 1500 km, but the upper ionosphere and thermosphere are mostly ignored.  Much detailed chemistry and optical/photon effects in the stratosphere and troposphere, but nothing useful about longwave thermal infrared transmission through the stratosphere.

The Wein thermal spectrum peak is 2898 μm⋅K, so the 250K layer of the stratosphere peaks at 12 μm infrared wavelengths.  Most graphs describe solar-photon Ångstrom-wavelength X-ray chemistry.
