1960F. S. Johnson in Jrnl. Geophysical Res. LXV. 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. 1973Q. Jrnl. R. Astr. Soc. XIV. 197 Estimates of the flux of ionization into and out of the protonosphere. 1975Physics Bull. July 338/3 (Advt.), There are vacancies for three Research Students, to commence in October 1975 and work for the degree of PhD... 2. Ionosphere and protonosphere by satellite radio transmissions.

1971Radio Science VI. 849/1 The observed fluxes must be lower limits to the total protonospheric fluxes, since H+ ions may also be differing from the protonosphere and contributing to the F-region via charge exchange below 800 km. 1978Nature 2 Feb. 428/1 Temporal changes of protonospheric content are indicative of the filling and draining of this region. |
