Orientation of the cross-field anisotropy of small-scale ionospheric irregularities and direction of plasma convection [PDF]
Annales Geophysicae, 2005 The relationship between the orientation of the small-scale ionospheric irregularity anisotropy in a plane perpendicular to the geomagnetic field and the direction of plasma convection in the F region is investigated.

Ionospheric irregularity reconstruction using multisource data fusion via deep learning [PDF]
Atmospheric Chemistry and Physics, 2023 Ionospheric sporadic E layers (Es) are intense plasma irregularities between 80 and 130 km in altitude and are generally unpredictable. Reconstructing the morphology of sporadic E layers is not only essential for understanding the nature of ionospheric ...

Single-Frequency Time-Step Ionospheric Delay Gradient Estimation at Low-Latitude Stations
IEEE Access, 2020 The irregularity of the local-area ionospheric delay is a primary impediment for Ground-Based Augmentation System (GBAS) services. Excessive ionospheric delay gradients may degrade aircraft positioning for high precision landing systems.

Diffusion spreading of middle-latitude ionospheric plasma irregularities [PDF]
Annales Geophysicae, 1995 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 B is examined using a three-dimensional rigorous numerical model of quasi ...

Remote SensingThe ionosphere of the Earth often becomes turbulent and develops electron density irregularities that can cause rapid and random changes in the amplitude and phase of radio signals, which is known as ionospheric scintillation.

Observations and modeling of scintillation in the vicinity of a polar cap patch
Journal of Space Weather and Space Climate, 2022 Small-scale ionospheric plasma structures can cause scintillation in radio signals passing through the ionosphere. The relationship between the scintillated signal and how plasma structuring develops is complex.

Identifying equatorial ionospheric irregularities using in situ ion drifts [PDF]
Annales Geophysicae, 2014 Previous climatological investigations of ionospheric irregularity occurrence in the equatorial ionosphere have utilized in situ measurements of plasma density to identify the presence of an irregularity.

Ionosphere modification and topology of ionospheric magnetically-oriented irregularities [PDF]
E3S Web of Conferences, 2020 One of the perspective directions of active impact on the ionosphere is the for-mation of electron concentration irregularities. Such irregularities can be used to increase the efficiency of radar systems and signal transfer in an interlayer ionospheric ...

The Long‐Term Trend of the Equatorial Electrojet Over Indian Sector
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract The upper‐atmosphere cooling trend is well documented, while the long‐term trend of the ionospheric electrodynamics remains poorly understood. Using two geomagnetic observation data sets over Indian sector, we analyze the long‐term trend of the monthly‐median equatorial electrojet (EEJ) in 1967–2015 after removing the solar activity and ...
