“…According to the results of spectrometric measurements (see, e.g., [7,8]), metal ions Fe + (M = 56), Mg + (M = 24), Ca + (M = 40), Al + (M = 27), Na + (M = 22), and Si + (M = 28) were detected in sporadic layers. It immediately follows from Eq.…”

We present the results of studying the sporadic layers of ionization in the lower ionosphere observed in the sunset-sunrise time during the summer months of 2000 and 2001. Measurements were performed at the "Sura" heating facility of the Radiophysical Research Institute (Nizhny Novgorod, Russia). Based on the analysis of the altitude-time dependences of the amplitude, relaxation time, and phase of the scattered signal, we obtain new data on the formation and dynamics of the evening and nighttime mid-latitude sporadic E layer, present the results of measuring the velocity of the plasma vertical motion, and estimate the relative molecular mass and total number density of metal ions whose pile-up due to the wind shear can cause the formation of the observed sporadic layers.

“…[ [Narcisi et al, 1972;Kopp and Herrmann, 1984], where n is the number of water molecules in the cluster. The reaction rate for the dissociative recombination of electrons with water cluster ions exceeds that of NO + and O + 2 by at least an order of magnitude [Reid, 1977].…”

[1] Estimates of the ambipolar diffusion coefficient producedusing meteor radar echo decay times display an increasing trend below 80-85 km, which is inconsistent with a diffusion-only theory of the evolution of meteor trails. Data from the 33 MHz meteor radar at King Sejong Station, Antarctica, have been compared with observations from the Aura Earth Observing System Microwave Limb Sounder satellite instrument. It has been found that the height at which the diffusion coefficient gradient reverses follows the height of a constant neutral atmospheric density surface. Numerical simulations of meteor trail diffusion including dissociative recombination with atmospheric ions and three-body attachment of free electrons to neutral molecules indicate that three-body attachment is responsible for the distortion of meteor radar diffusion coefficient profiles at heights below 90 km, including the gradient reversal below 80-85 km. Further investigation has revealed that meteor trails with low initial electron line density produce decay times more consistent with a diffusion-only model of meteor trail evolution.

“…In addition to positive ions, a large number of negative ions listed in Tables 8 and 9 were observed at the D-region altitudes of the ionosphere during rocket flights using ion mass (Narcisi et al 1971(Narcisi et al , 1972a(Narcisi et al , b, 1983Arnold et al 1971André 1984). In addition to UT, the zonal local time LT is used in Table 4.…”
