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

open access: yesApplied 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

open access: yesGeophysical 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‐

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

open access: yesFrontiers 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 ...

The dependence of F-region electron heating on HF radio pump power: Measurements at EISCAT Tromsø [PDF]

open access: yes, 2012
[1] Measurements of ionospheric electron temperature enhanced by the action of a powerful high-frequency radio wave on the F-region at the EISCAT facility near Tromsø, Norway are analyzed to obtain the electron heat source due to the radio wave as a ...

Diffusion spreading of middle-latitude ionospheric plasma irregularities

open access: yesAnnales 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 ...

Deep Learning Insights Into Ionospheric Sporadic E Irregularities Under Different Solar Activity Conditions

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Solar activity profoundly modulates many atmospheric coupling systems, particularly the morphology of the ionospheric irregularities, which is crucial for reliable radio communication.

Topside Ionization and Effect on Altitudinal Evolution of Nocturnal Ionospheric Irregularities

open access: yesSpace Weather
Topside ionospheric electron density (Ne) and its control on the variabilities in nocturnal ionospheric irregularities is examined globally using electron density measurements from COSMIC‐2 and Swarm satellite, along with the Swarm satellite‐based ...
