Phase perturbation measurements through a heated ionosphere [PDF]

High frequency radiowaves incident on an overdense (i.e., HF-frequency penetration frequency) ionosphere produce electron density irregularities. The effect of such ionospheric irregularities on the phase of UHF-radiowaves was determined.

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 ...

A comparison between large‐scale irregularities and scintillations in the polar ionosphere

Geophysical Research Letters, 2016
A comparison tool has been developed by mapping the global GPS total electron content (TEC) and large coverage of ionospheric scintillations together on the geomagnetic latitude/magnetic local time coordinates. Using this tool, a comparison between large‐

Technical issues in the conduct of large space platform experiments in plasma physics and geoplasma sciences [PDF]

Large, permanently-manned space platforms can provide exciting opportunities for discoveries in basic plasma and geoplasma sciences. The potential for these discoveries will depend very critically on the properties of the platform, its subsystems, and ...

Interferometry of ionospheric E-region irregularities based on Kunming VHF radars

Frontiers in Astronomy and Space Sciences
There is a long history of using VHF radar systems to detect ionospheric irregularities based on the theory of coherent scattering. According to previous work, there is a high occurrence of field-aligned irregularities (FAIs) in the ionospheric E-region ...

Planar ion trap (retarding potential analyzer) experiment for atmosphere explorer [PDF]

The retarding potential analyzer and drift meter were carried aboard all three Atmosphere Explorer spacecraft. These instruments measure the total thermal ion concentration and temperature, the bulk thermal ion velocity vector and some limited properties

Diffusion spreading of middle-latitude ionospheric plasma irregularities

Annales Geophysicae
In contrast to the way that the spreading of irregularities in a plasma is usually considered, the diffusion spreading of irregularities stretched along the geomagnetic field <strong>B</strong> is examined using a three-dimensional rigorous ...
