“…The daytime electron density profile illustrated in Figure 12 shows that the sum of the electron and ion temperatures taken in both the He+ and O+ regions are approximately the same. The constancy of this sum with altitude also can be inferred in published data (KING, 1963) from the Alouette Topside Sounder Satellite. This is evidence either that the differences in the electron, ion and neutral gas temperatures are vanishingly small above 450 km or that the ion temperature transition proposed by HANSON occurs above 1000 km, if at all.…”

“…In the more recent years, however, it has become evident that the individual dissociative recombination rates of the dominant molecular ions are approximately equal to one another. That is, [Biondi, 1964] [3.8 ± l.O] X I0-7 [Kasner, Rogers, and Biondi, 1961] Nt+e~N+N [2.8±0.5] X I0-7 [Biondi, 1964] [5. 9 ± l.O] X I0-7 [Kasner, Rogers, and Biondi, 1961] NO++e~N+O [ =5 X 1Q-7 ) [Gunton and Shaw, 1965].…”

The effect of meteoric dust particles on the steady-state distribution of electrons and ious in the lower ionosphere (SQ-90 km) has been investigated. A formal expression for the effective recombination coefficient has also been derived, containing the terms for the rates of capture of electrons and positive and negative ions by the dust. These capture rates are derived by an extension of Natanson's theory of aerosol charging by the capture of ions. The altitude dependence of these coefficients is mainly determined by the altitude distribution of the dust concentration. It is found that only particles with radii larger than about a tenth of a micron play a significant role.The numerical values of the effective recombination coefficient for several altitudes in the D region have been compared with the values empirically determined by us from multiple-frequency radiowave absorption data in the auroral zone, and found to be in satisfactory argeement. It is also .shown that the role of dust-concentration in the D region is of major significance when the ionization density is weak to moderate. For a strongly ionized D region, the role is significant only if the dust concentration is higher than is currently believed probable.

“…Nicolet and Hunaerts [1955] concluded that a minimum value of 4 X 10 -s cm 3 sec -• can be deduced from these measurements. Kasner et al [1961] reported a value of (3.8 •-1) X 10 -7 cm3 sec -• at 300øK determined by laboratory measurement. However, Swider [1963] quotes Biondi as indicating that this value should be reduced by a factor of 2.…”

A method by which the recombination coefficient of the nighttime F region of the ionosphere can be determined, previously applied to mean monthly Puerto Rico true height profiles, has been applied to results from six sounding stations at different latitudes. Further work has been done on the effect of various assumptions used in the analysis. No large latitude dependence of the recombination coefficient at 300 km was observed. A large seasonal effect was found, however. The analysis has been extended to the calculation of vertical diffusion and total transport velocities, and a determination of the diffusion coefficient effective in the nighttime F region was obtained. The diffusion coefficient was found to be for current models for the neutral atomic oxygen density. Vertical drift velocities determined from mean monthly profiles derived from hours for which Kρ was less than 4.5 were found to be generally lower than 10 m/sec.
