Real-time detection of tsunami ionospheric disturbances with a stand-alone GNSS receiver. A preliminary feasibility demonstration [PDF]

, 2017
It is well known that tsunamis can produce gravity waves that propagate up to the ionosphere generating disturbed electron densities in the E and F regions. These ionospheric disturbances can be studied in detail using ionospheric total electron content (

Solar Wind‐Magnetosphere‐Ionosphere Coupling During the October 2024 Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Two geomagnetic storms occurred in October 2024 (Oct 6‐9 and 10–12), driven by the impact of a series of interplanetary coronal mass ejections on the magnetosphere. The first was a moderate storm, with peak Sym‐H near −150 nT, whereas the second was intense, Sym‐H reaching −340 nT.

Estimating traveling ionospheric disturbance propagation direction and speed using bistatic high-frequency oceanographic radars

Journal of Space Weather and Space Climate
The purpose of this investigation is to demonstrate how observations from a network of Coastal Ocean Dynamics Applications Radars (CODARs) can be used to derive the parameters of a traveling ionospheric disturbance (TID) in the mid-latitudes.

Ionospheric disturbances over South America related to Tonga volcanic eruption

Earth, Planets and Space, 2023
On January 15, 2022, we observed various unusual atmospheric wave events over South America: Atmospheric pressure waves (Lamb mode) around 12:30 to 17:30 UT, tsunamis along the Chilean coast at around 17:00 to 19:00 UT, and ionospheric disturbances ...

Insights into the nature of northwest-to-southeast aligned ionospheric wavefronts from contemporaneous Very Large Array and ionosondes observations

, 2012
The results of contemporaneous summer nighttime observations of midlatitude medium scale traveling ionospheric disturbances (MSTIDs) with the Very Large Array (VLA) in New Mexico and nearby ionosondes in Texas and Colorado are presented.

Medium-scale traveling ionospheric disturbances by three-dimensional ionospheric GPS tomography [PDF]

Earth, Planets and Space, 2016
In this study, we develop a three-dimensional ionospheric tomography with the ground-based global position system (GPS) total electron content observations. Because of the geometric limitation of GPS observation path, it is difficult to solve the ill-posed inverse problem for the ionospheric electron density.

Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

Longitudinal effects of ionospheric responses to substorms at middle and lower latitudes: a case study [PDF]

Annales Geophysicae, 1995
An ionospheric model is used to simulate total electron content (TEC) disturbance events observed at middle and lower latitude sites near 75°W and 7°E longitudes.

Impacts of acoustic and gravity waves on the ionosphere

Frontiers in Astronomy and Space Sciences, 2022
The impact of regional-scale neutral atmospheric waves has been demonstrated to have profound effects on the ionosphere, but the circumstances under which they generate ionospheric disturbances and seed plasma instabilities are not well understood ...
