Study on Ionospheric Depletion and Traveling Ionospheric Disturbances Induced by Rocket Launches Using Multi-Source GNSS Observations and the MRMIT Method

Remote Sensing
Rocket launches constitute a major anthropogenic source of disturbance in the near-Earth space environment, inducing significant ionospheric perturbations through both chemical and dynamic mechanisms.

Penetration of internal gravity waveguide modes into the upper atmosphere

Solar-Terrestrial Physics, 2016
The paper describes internal gravity waveguide modes, using dissipative solutions above the source. We compare such a description with an accurate approach and a WKB approximation for dissipationless equations.

Isolated ionospheric disturbances as deduced from global GPS network [PDF]

Annales Geophysicae, 2004
We investigate an unusual class of medium-scale traveling ionospheric disturbances of the nonwave type, isolated ionospheric disturbances (IIDs) that manifest themselves in total electron content (TEC) variations in the form of single aperiodic ...

Limb sounders tracking topographic gravity wave activity from the stratosphere to the ionosphere around midlatitude Andes [PDF]

, 2015
Several studies have shown that the surroundings of the highest Andes mountains at midlatitudes in the Southern Hemisphere exhibit gravity waves (GWs) generated by diverse sources which may traverse the troposphere and then penetrate the upper layers if ...

Deep Quake Dynamics: A Multimodal Fault‐Aware Approach to Earthquake Magnitude and Occurrence Time Forecasting

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
EQMT integrates earthquake catalog data, fault‐network geometry, engineered features, and graph embeddings in a unified framework for forecasting earthquake magnitude and occurrence time. The framework is designed to reflect inter‐fault spatial dependencies together with temporal seismic patterns, addressing limitations of approaches based only on ...

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.

Observations of poleward-propagating large-scale traveling ionospheric disturbances in southern China [PDF]

Annales Geophysicae, 2013
We report here on two cases of poleward-propagating large-scale traveling ionospheric disturbances (LSTIDs) in China during a medium-scale storm between 27 May and 1 June 2011.

Modeling the ionospheric response to traveling atmospheric disturbances [PDF]

Journal of Geophysical Research: Space Physics, 1997
Anomalous increases of the ionization density at middle latitudes (positive ionospheric storms) are often a prominent feature of upper atmospheric storms. One of their possible causes are traveling atmospheric disturbances (TADs) which propagate from polar to equatorial latitudes, carrying along equatorward‐directed meridional winds.

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

Ionospheric Disturbances Triggered by the Mw7.6 Earthquake off the Coast of El Salvador on 13 January 2001

Terrestrial, Atmospheric and Oceanic Sciences, 2006
A network of five ground-based receivers of the global positioning sys- tem (GPS) was use to detect seismo-ionospheric disturbances in the total elec- tron content (TEC) triggered by the 13 January 2001 El Salvador Mw 7.6 earthquake.
