Coupling of the solar wind, magnetosphere and ionosphere by MHD waves [PDF]

, 2012
The solar wind, magnetosphere and ionosphere are coupled by magnetohydrodynamic waves, and this gives rise to new and often unexpected behaviours that cannot be produced by a single, isolated part of the system.

Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

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 ...

Evaluation of a Soviet-Era Gravimetric Survey Using Absolute Gravity Measurements and Global Gravity Models: Toward the First National Geoid of Kazakhstan

Geosciences
Determining a high-precision national geoid is a fundamental step in modernizing Kazakhstan’s vertical reference system. However, the country’s vast territory, complex topography, and limited coverage of modern terrestrial and airborne gravimetric ...

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 ...

Interplanetary magnetic field control of fast azimuthal flows in the nightside high-latitude ionosphere [PDF]

, 2008
SuperDARN radar data from both hemispheres for the interval January 1999 to November 2006 have been inspected for evidence of high-speed azimuthal flows in the nightside high-latitude ionosphere.

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 ...
