Dusty plasma effects in the nighttime ionosphere of mars
2020<p>A self-consistent consideration of the motion of dust particles in plasma systems in the atmosphere of Mars can lead to the detection of oscillations and waves, which, in particular, can be detected from the surface of the planet.

The dataset contains the intergrated plasma density, Pedersen conductivity, polarization electric filed and the results of 9 simulation runs generated by the simulation of nighttime medium-scale traveling ionospheric disturbances, which is used to investigate the effects of electic field, wind field and magnetic dip angle in the simulation of MSTIDs in

A study of the nighttime ionosphere and its reaction rates
Journal of Geophysical Research, 1965Analysis of the nighttime ionosphere suggests that the reactions O+ + N2 → (rate γ1) → NO+ + N and O+ + O2 → (rate γ2) → O2+ + O are 3 × 10−13 cm3 sec−1 and 3 × 10−12 cm3 sec−1, respectively, within a factor of about 3. An additional requirement is that γ1/γ2 = 0.1 within a factor of about 2.

The ionospheric absorption of downgoing whistler waves during nighttime
Journal of Atmospheric and Terrestrial Physics, 1971Abstract A full-wave method is used to examine the transmission and internal reflection of waves incident on the nighttime ionosphere from above at moderate and low latitudes. The results are used to examine how the absorption of whistler waves incident vertically varies with height.

Abstract Using an electron transport model, we calculate the electron density of the electron impact-produced nighttime ionosphere of Mars and its spatial structure. As input we use Mars Global Surveyor electron measurements, including an interval when accelerated electrons were observed.

Rayleigh‐Taylor and wind‐driven instabilities of the nighttime equatorial ionosphere
Journal of Geophysical Research: Space Physics, 1979We have made a thorough re‐examination of the Rayleigh‐Taylor instability in the nighttime equatorial ionosphere from ∼100 km to the bottomside F region. We have taken into account explicitly the following effects which have been ignored by other workers in various combinations: (1) The eastward drift of the ionosphere caused by the nighttime ...

Equatorial Plasma Bubbles Encounter With the Nighttime Ionosphere Enhancement
Journal of Geophysical Research: Space PhysicsAbstract On the two consecutive days of February 26–27, 2014, the all‐sky airglow imager in Qujing observed Equatorial Plasma Bubbles (EPBs) dissipating more rapidly than those that appeared before and after. While these rapidly dissipating EPBs were present, the Hainan COherent‐scatter Phased Array Radar (HCOPAR) detected Field ...

Evaluation of nighttime exponential ionospheric models using VLF atmospherics
Radio Science, 1974Measurements of very low frequency (VLF) atmospherics were made simultaneously at a station close to the lightning sources (Norman, Oklahoma) and at stations 1787 km (La Posta, California) and 5912 km (Kamuela, Hawaii) from Norman. Timing synchronization was maintained between stations to better than 10 μsec which, coupled with the source bearing from ...

Abstract The effect on the ionization redistribution in the nighttime ionosphere by the neutral atmospheric wind was studied quantitatively by using the sounding rocket data of the electron density by L. G. Smith, and of the neutral wind by Constantinides and Bedinger.

The effect of dynamic processes on the E-region structure of the nighttime ionosphere
Journal of Atmospheric and Terrestrial Physics, 1974Abstract According to results of neutral wind measurements the electron concentration profiles in the night mid-latitude E -region in some experiments were calculated taking into account two sorts of ions—the molecular and the long-lived ions. The profiles obtained were compared with the experimental ones.
