Oxygen Pickup Acceleration in the Plasma Mantle Associated With Traveling Flux‐Rope Structures

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract It is well known that, in the high‐altitude cusp and mantle regions, ionospheric‐origin outflowing oxygen (O+) ions are often energized through non‐adiabatic processes, among which cyclotron resonance is considered a major mechanism. Here, based on Cluster observations, we present evidence that pickup acceleration also operates as a non ...

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.

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

Cosmic Radiation Dose‐Rates for Civil Aviation in the Middle East: Vertical Structure, Solar Modulation, and Comparison With Models

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract High‐altitude balloon measurements were conducted over southern Israel (30°35′N, 34°45′E; 850 m a.s.l., geomagnetic rigidity cutoff 10.3 GV) to characterize the vertical profiles of atmospheric ionization and radiation up to ∼35 km. Six balloon launches between October 2014 and August 2016 recorded the variability of atmospheric ionization ...

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 ...

Shining light on the aurora's contributions to people: A qualitative study of the aurora borealis in Greenland

People and Nature, Volume 8, Issue 9, Page 3122-3144, September 2026.
Abstract The aurora borealis (northern lights) is an abiotic natural phenomenon that contributes to human well‐being. There is currently a significant research gap in primary qualitative valuation of the aurora's links to people. This exploratory qualitative study applies the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES ...
