The Radiation Transfer at a Layer of Magnetized Plasma With Random Irregularities [PDF]

, 1998
The problem of radio wave reflection from an optically thick plane monotonous layer of magnetized plasma is considered at present work. The plasma electron density irregularities are described by spatial spectrum of an arbitrary form.

Small-Scale Ionospheric Irregularities of Auroral Origin at Mid-latitudes during the 22 June 2015 Magnetic Storm and Their Effect on GPS Positioning

Remote Sensing, 2020
Small-scale ionospheric irregularities affect navigation and radio telecommunications. We studied small-scale irregularities observed during the 22 June 2015 geomagnetic storm and used experimental facilities at the Institute of Solar-Terrestrial Physics

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 waveguide.

GPS TEC Fluctuations in the Low and High Latitudes During the 2015 St. Patrick`s Day Storm [PDF]

Journal of Astronomy and Space Sciences, 2017
As a part of collaborative efforts to understand ionospheric irregularities, the Korea ionospheric scintillation sites (KISS) network has been built based on global positioning system (GPS) receivers with sampling rates higher than 1 Hz.

The climatology of ionospheric plasma bubbles and irregularities over Brazil [PDF]

Annales Geophysicae, 2005
In this paper, we examine ionospheric plasma depletions (or bubbles) and irregularities observed by photometers and a ground-based receiver of the global positioning system (GPS) both located in Brazil, South America.

On effective conductivity of the ionosphere with random irregularities [PDF]

Annales Geophysicae, 1995
The influence of stochastic irregularities of the ionosphere on its effective conductivity has been estimated. The study was carried out for large scale inhomogeneities and quasistationary electromagnetic fields.

Origin of Intense Plasma Depletions After Midnight Over the Korean Peninsula During the Geomagnetic Storm on 11 May 2024

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract A band of total electron content (TEC) depletions of about 5–15 TEC unit passed over the Korean Peninsula after midnight during the geomagnetic storm on 11 May 2024. This magnitude of TEC depletions has not been previously reported in the region.

On the Production of Ionospheric Irregularities Via Kelvin‐Helmholtz Instability Associated with Cusp Flow Channels

Journal of Geophysical Research: Space Physics, 2020
We present a multi‐instrument multiscale study of a channel of enhanced, inhomogeneous flow in the cusp ionosphere occurring on November 30, 2014. We provide evidence that strong Global Navigation Satellite System (GNSS) phase scintillations indices (σϕ ...
