Imprint of the Quasi‐Biennial Oscillation on the Ionosphere and Thermosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is a dominant mode of stratospheric variability and is known to modulate the variability of the ionosphere‐thermosphere (IT) system. However, the extent of its influence on the ionosphere‐thermosphere system remains uncertain due to weak signals and confounding with similar periodicities in solar flux.

The use of GPS-arrays in detecting shock-acoustic waves generated during rocket launchings [PDF]

, 2000
This paper is concerned with the form and dynamics of shock-acoustic waves (SAW) generated during rocket launchings. We have developed a method for determining SAW parameters (including angular characteristics of the wave vector, and the SAW phase ...

Pilot Ionosonde Network for Identification of Traveling Ionospheric Disturbances

Radio Science, 2018
AbstractTraveling ionospheric disturbances (TIDs) are the ionospheric signatures of atmospheric gravity waves. Their identification and tracking is important because the TIDs affect all services that rely on predictable ionospheric radio wave propagation.

Statistical Study of Short Large‐Amplitude Magnetic Structures at Mars Observed by MAVEN

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a statistical study of Short Large‐Amplitude Magnetic Structures (SLAMS) in the Martian foreshock using data from the Mars Atmosphere and Volatile Evolution (MAVEN) mission between 01 January 2015 and 31 December 2019. We have identified 21,008 SLAMS during this time interval and statistical results are presented on the SLAMS ...

Detection and Description of the Different Ionospheric Disturbances that Appeared during the Solar Eclipse of 21 August 2017

Remote Sensing, 2018
This work will provide a detailed characterization of the travelling ionospheric disturbances (TIDs) created by the solar eclipse of 21 August 2017, the shadow of which crossed the United States from the Pacific to the Atlantic ocean.

Joule Heating in the Northern Hemisphere During Geomagnetic Storms Driven by High‐Speed Streams and Coronal Mass Ejections

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract We present a robust method for estimating the auroral Joule heating in the northern hemisphere by combining SuperMAG, SuperDARN and AMPERE data products. This method is applied to 292 storms during 2010–2023. Temporal evolution and spatial distributions of the storm‐time Joule heating are studied using a superposed epoch analysis, with the ...

Taxonomy of IMT Interference on Aeronautical Systems

Radio Science, Volume 61, Issue 4, April 2026.
Abstract The rapid deployment of 5G and future 6G networks has raised concerns about interference with critical aeronautical systems, particularly radio altimeters and Wireless Avionics Intra‐Communications (WAIC). This paper offers a comprehensive taxonomy of the 5G/6G signal interference mechanisms, operational impacts, and mitigation strategies in ...

Wavelet analysis of the ionospheric response at mid-latitudes during the April 200 storm using magnetograms and vTEC from GPS [PDF]

, 2013
In this work we pursue the idea of computing a parameter that allows us to estimate the local ionospheric response to a geospheric event that triggers an ionospheric storm. For that, wavelet technique has been chosen because of its ability to analyze non-

The correlation of VLF propagation variations with atmospheric planetary-scale waves [PDF]

Variations in the received daytime phase of long distance, cesium-controlled, VLF transmission were compared to the height variations of the 10-mb isobaric surface during the first three months of 1965 and 1969.
