1960 F. S. Johnson in Jrnl. Geophysical Res. 65 578/1 The name protonosphere is adopted here to describe the ionized medium above about 1800 km where protons are the principal ionized constituent, the name ionosphere being reserved for the lower region consisting of heavier atmospheric ions, such as atomic oxygen.
1973 Q. Jrnl. Royal Astron. Soc. 14 197 Estimates of the flux of ionization into and out of the protonosphere.
2004 Adv. in Space Res. 33 959 It is now well known that in the topside ionosphere thermal conduction from the protonosphere becomes the dominant factor over the heating and loss terms in shaping the ionospheric electron temperature.
