Ionospheric and magnetospheric plasmapauses' [PDF]

open access: yes
During August 1972, Explorer 45 orbiting near the equatorial plane with an apogee of about 5.2 R sub e traversed magnetic field lines in close proximity to those simultaneously traversed by the topside ionospheric satellite ISIS 2 near dusk in the L ...

Investigations of the ionospheric using radio signals from artificial satellites [PDF]

open access: yes
The occurrence and characteristics of ionospheric irregularities in medium latitudes and in polar regions were measured using radio signals from artificial satellites. Ionospheric changes during quiet and disturbed conditions were also measured. Electron

The evolution of electron density and temperature distributions in the topside ionosphere during magnetic storms [PDF]

open access: yes
The latitudinal distributions of electron density and temperature during geomagnetic storms in the mid-latitude topside ionosphere are observed to change in a manner than can be related to the evolution of ring current particle populations. The region of

Downward auroral currents from the reconnection Hall-region [PDF]

open access: yes, 2011
We present a simple (stationary) mechanism capable of generating the auroral downward field-aligned electric field {that is} needed for {accelerating the ionospheric electron component up into the magnetosphere and confining the ionospheric ions at low ...

Kinetic response of ionospheric ions to onset of auroral electric fields [PDF]

open access: yes
Examination of the exact analytic solution of a kinetic model of collisional interaction of ionospheric fions with atmospheric neutrals in the Bhatnagar-Gross-Krook approximation, shows that the onset of intense auroral electric fields in the topside ...

Topside Refractive Irregularities and Travelling Ionospheric Disturbances [PDF]

open access: yesAustralian Journal of Physics, 1967
Munro (1950) deduced from ground-based observations that traveling ionospheric disturbances (T.LD.'s) are large-scale distortions of the electron density contours, which travel through the ionosphere, and Calvert and Schmid (1964) attributed extra traces and distortions of the main echo traces, which occur near the critical frequency of topside ...

Combination of High-Rate Ionosonde Measurements with COSMIC-2 Radio Occultation Observations for Reference Ionosphere Applications

open access: yesAtmosphere
Knowledge of ionospheric plasma altitudinal distribution is crucial for the effective operation of radio wave propagation, communication, and navigation systems.

Explanation of the computer listings of Faraday factors for INTASAT users [PDF]

open access: yes
Using a simplified form of the Appleton-Hartree formula for the phase refractive index, a relationship was obtained between the Faraday rotation angle along the angular path and the total electron content along the vertical path, intersecting the angular

Continuation of data analysis from the ion mass spectrometer on the ISIS-2 spacecraft [PDF]

open access: yes
The spectrometer measures the composition and number density of the positive ion species in the ionosphere as well as the ion flux normal to the spacecraft trajectory. The measurement of high latitude ionospheric dynamics is reported.
