Variations of topside ionospheric electron density near the dawn terminator in relation to geomagnetic activity

Journal of Space Weather and Space Climate, 2017
A statistical study to determine the influence of geomagnetic disturbances on the ionosphere across the dawn terminator at subauroral and middle latitudes is performed, based on the vertical electron density profiles measured by the GPS Occultation ...

Hydrogen & Oxygen Ion Densities & Fluxes In Low & Midlatitude Topside Ionosphere [PDF]

, 1974
284-288The daytime altitudinal variation of ion diffusion flaxes and their influence on H+ and O+ densities in the topside ionosphere in the low and midlatitudes are investigated theoretically, taking into account the ionosphere protonosphere coupling ...

Investigation for Possible Association of the Topside and Bottomside Ionospheric Irregularities over the Midlatitude Ionosphere

Applied Sciences
The present study investigates the characteristics of ionospheric irregularities at middle latitudes by examining the association between spread F (SF) events detected by Digisondes and medium-scale travelling ionospheric disturbances (MSTIDs) detected ...

Identification and characterization of the topside bulge of the Venusian ionosphere

Icarus
Venus, in the absence of an intrinsic magnetic field, undergoes a direct interaction between its ionosphere and the solar wind. Previous missions, including Mariner, Venera, and the Pioneer Venus Orbiter (PVO), reported a recurring localized increase in electron density, often termed a "bulge," at altitudes between 160 and 200 km.

The effect of counter electrojet on the plasma distribution of the topside ionosphere

, 1987
Evidence of strong correlation between the counter electrojet and the behaviour of the topside ionosphere is presented here. The reality of the counter electrojet is established by the magnetic field variations of the H-component and the bottom side ...

Sporadic E-like Topside Layer Driven by Wind Shear in the Martian Ionosphere

The Astrophysical Journal
Ionospheric plasma density disturbances significantly affect radio wave propagation, impacting communication and planetary exploration. At Earth, sporadic E layers (Es) are commonly observed. They are characterized by thin, high-density plasma structures
