“…This is important primarily as regards the study of the ionosphere and terrestrial and cosmic space. For example, diffusion plays an important part in problems dealing with the formation and the shape of ionospheric layers [2][3][4][5][6][7][8][9], clouds of artificial ionization set up by rockets and high-altitude explosions [10][11][12][13][14], the origin and structure of ionospheric inhomogeneities [15][16][17][18], and in particular inhomogeneities in the E layer which result from hydrodynamic turbulence [19,20]. Diffusion processes play a determining part in the formation of trails of meteorites, satellites, and rockets in the ionosphere [21][22][23], as well as in the scattering of radio waves by these trails [24][25][26][27][28].…”

“…The concentration n, cm -• of an ionospheric ion s is governed by the continuity equation The electrostatic field may arise because of charge separation in the magnetosphere or in the atmospheric dynamo region [cf. Fejer, 1953Fejer, , 1963Fejer, , 1964Dougherty, 1961;Kendall, 1964;Gliddon, 1965].…”

The successful measurements of ionospheric composition by Holmes et al. [1965] have stimulated a number of recent papers discussing ionospheric chemistry. These papers attempt to deduce rate coefficients for important ion reactions, using an approach based on an assumption of chemical equilibrium. In the present note we shall examine the validity of this assumption. We shall demonstrate that chemical equilibrium is not actually realized in the nighttime ionosphere, at least over the altitude range covered by Holmes et al. [1965], During the day, however, photochemical equilibrium is a valid approximation, at least below 230 km.

The magnetoplasma diffusion equation of the F2 region of the ionosphere is derived in its primitive form, allowing for electric currents flowing between conjugate points of the dynamo region, and for temperature variations.It appears that the standard view of the ambipolar diffusion problem is correct. The ion-electron pairs may be thought of as sliding down the magnetic field lines with diffusive motion, while the whole field line drifts at right angles t o itself.The electric current along a field line would affect the ionization only if its magnitude were 100 times greater than Dougherty's estimate' of io-' amps/m2.
