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 ...

Connection between ENSO phenomena and solar and geomagnetic activity [PDF]
Natural Hazards and Earth System Sciences, 2002 Connections between El Niño – Southern Oscillation (ENSO) phenomena and indices of solar activity and geomagnetic disturbance were investigated. Spectral analysis of the ENSO-data was carried out.

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.

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

Mid-latitude ionosphere during two great geomagnetic storms
, 1996 The ionospheric disturbances observed at many European ionosonde stations in association with the severe geomagnetic storms occurring on 19-20 December 1980 and 11-12 April 1981 were investigated by using the available ionospheric and geomagnetic data ...

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 ...

First GIC Estimates for the Mexican Power Grid
Space Weather, 2020 This contribution addresses the first assessment of the impact of geomagnetically induced currents (GIC) on the 400‐kV power grid of Mexico. As an initial approach, we modeled GIC using a uniform conductivity for the entire Mexican territory and ...

Azimuth estimation based on CNN and LSTM for geomagnetic and inertial sensors data
ICT ExpressAlthough estimating the azimuth using a geomagnetic sensor is very useful, the estimation error may be very large due to the surrounding geomagnetic disturbance.

AtmosphereIn the paper we consider the pulsed disturbances caused in the ionosphere by an extreme G5-level geomagnetic superstorm on 10 May 2024, and by the X1.0 and M-class solar flares on 8 May 2024, which preceded the storm.
