   • Dave frowned as he tried to answer. "Well, I suppose the atmosphere is oxygen and nitrogen, mostly; then there's the ionosphere and the ozone layer. As I remember, the color of the sky is due to the scattering of light—light rays being diffracted in the air." 1963, Lester del Rey, The Sky Is Falling:
   • Solar storms drive currents of millions of amps through the electrically conductive upper layer of our atmosphere (known as the ionosphere). These currents, which can fluctuate rapidly, drive powerful magnetic disturbances at the Earth's surface that in turn induce electrical currents in the planet's crust. 2023 November 15, Prof. Jim Wild, “This train was delayed because of bad weather in space”, in RAIL, number 996, page 30:
2. The similar region of the atmosphere of another planet.
