Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Travelling ionospheric disturbance over California mid 2000 [PDF]

Nonlinear Processes in Geophysics, 2006
Abstract. In this paper, the GPS data collected by more than 130 permanent GPS stations that belong to the Southern California Integrated GPS Network (SCIGN) around the launch of a Minuteman-II missile on 8 July 2000 (UTC) is processed to reveal traveling ionospheric disturbance (TID) all over the network on average 15 min after the launch.

Dataset of Quiet Space Weather Periods for Ionospheric Studies

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract The ionosphere is a dynamic environment regularly affected from above and from below. This study identifies periods within the years 2000–2023 when the impact from above, driven by space weather, was minimal. The quiet space weather periods have wide usage for two types of ionospheric studies. At first, studies of isolated space weather events

Travelling Ionospheric Disturbances in the F Region [PDF]

Australian Journal of Physics, 1958
Observations of the horizontal movements of travelling ionospheric disturbances recorded on a single radio frequency from April 1948 to March 1957 are analysed for seasonal and diurnal variations of occurrence and of direction and speed of travel. Recording was mainly in daylight hours but some limited night results are included.

OH Airglow for Ionospheric Seismology Applications—From Instrumental Noise Characterization to Rayleigh Waves Detection Threshold

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Airglow layers are powerful tracers of upper‐atmosphere dynamics because of their sensitivity to a broad spectrum of atmospheric wave phenomena. Seismic activity, and in particular Rayleigh waves, constitutes a forcing mechanism capable of generating infrasonic waves in the atmosphere.

An explainable Machine Learning model for Large-Scale Travelling Ionospheric Disturbances forecasting

Journal of Space Weather and Space Climate
Large-Scale Travelling Ionospheric Disturbances (LSTIDs) are wave-like ionospheric fluctuations, generally triggered by geomagnetic storms, which play a critical role in space weather dynamics.
