Thousand‐Kilometer‐Scale Wavelike Undulations in Ionospheric Plasma Bubble Lifetime and Development Over Wide Longitudes

Geophysical Research Letters
The irregularities of ionospheric plasma bubbles (EPBs) sequentially generated over wide longitudes are expected to share similar lifetime under normal conditions.

Multiscale Modeling of Ionospheric Irregularities [PDF]

, 2014
Abstract : Developed novel multi-nesting, time splitting and implicit relaxation techniques for coupled three-dimensional mesoscale/microscale ionospheric dynamics; resolved secondary Rayleigh-Taylor instabilities and characterized turbulent dynamics of plasma bubbles/ionospheric layers.

Characteristics of Ionospheric Irregularities Using GNSS Scintillation Indices Measured at Jang Bogo Station, Antarctica (74.62°S, 164.22°E)

Space Weather, 2020
Global Navigation Satellite System (GNSS) signals strongly depend on the ionospheric conditions, which are composed of electrons and ions generated by solar radiation and particle precipitation.

Correlation of High‐Latitude Scintillation With Auroral Precipitation: Case Studies Using GNSS Radio Occultation Data From PlanetiQ

Space Weather
This study presents a survey of high‐latitude ionospheric scintillation using GNSS radio occultation (RO) data from the PlanetiQ satellite. The analysis examines 483 high‐latitude RO tracks between January and May 2023, with 371 tracks exhibiting ...

Ionospheric irregularity behavior during the September 6–10, 2017 magnetic storm over Brazilian equatorial–low latitudes

Earth, Planets and Space, 2019
The September 6–10, 2017 two-step magnetic storm was caused by an X9 solar flare followed by a CME. The SSC that occurred at 23:43 UT on day 06 when Sym-H reached about 50 nT, was due to a sudden increase in solar wind.

Long Period Ionospheric Disturbances Induced by Atmospheric Pressure Waves From the 2022 Tonga Volcanic Eruption

Earth and Space Science
The Tonga‐Hunga volcanic eruption on 15 January 2022 at 04:14:54 UTC produced large perturbations in the lower atmosphere and ionosphere globally. We report that the long period (0.28–16.67 mHz) ionospheric disturbances followed the surface pressure ...

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

Journal 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.

Statistical Study on the Effect of Meridional Neutral Wind on the Occurrence of Post‐Sunset Equatorial Ionospheric Irregularities

Space Weather
The navigation and radio communication systems experience significant disruptions due to post‐sunset equatorial ionospheric irregularities. There is ongoing debate regarding the impact of meridional/trans‐equatorial wind speed on these irregularities ...
