Aircraft Ionizing Radiation Exposure for Solar Cycle 24/25 From ARMAS and NAIRAS

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Exposure to ionizing radiation from galactic cosmic rays and solar energetic particles at aviation flight altitudes can have an adverse effect on human health. Although airline crews are classified as radiation workers by the International Commission on Radiological Protection (ICRP), in most countries, their level of exposure is unquantified ...

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations

Geophysical Research Letters
Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth's inner magnetosphere. While previous studies have linked hiss wave enhancements in the outer plasmasphere (just inside the plasmapause)

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Characteristics of VLS Hiss Observed by S-310JA-2 Rocket

Antarctic Record, 1979
VLF hiss was observed on the S-310JA-2 rocket at Syowa Station in the Antarctic region (69°00'S, 39°35' E) at 03 22 LT on February 10, 1977, during polar magnetic storm (ΔH, -680γ) This hiss was observed only with a 24 m tip-to-tip electric dipole ...

Sosiale roller og lokale og globale interesser i vurderingen av språksituasjoner

Nordlyd: Tromsø University Working Papers on Language & Linguistics, 2013
Kommer det samiske språket til å dø ut? Trusler mot det språklige mangfoldet og mulig språkdød er hyppig diskutert i det flerspråklige Nord-Norge. Deltakere i denne diskursen er talere, lokale aktører, forskere og fageksperter, statlige myndigheter ...

Atmospheric Tides Imprint a Wavenumber‐4 Structure in Topside Ionospheric ELF Wave Intensity

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Atmospheric tides produce a well known pronounced longitudinal wavenumber‐4 (WN‐4) structure in the ionosphere, but their influence on electromagnetic‐wave propagation through the ionosphere remains poorly constrained. Here we use DEMETER satellite measurements to show that the extremely low frequency (ELF) electric field in the low‐latitude ...

Electron Scattering by Highly Oblique Quasi‐Electrostatic Chorus Waves Under Realistic Magnetospheric Conditions

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Using Van Allen Probes data (2013–2015), we report that highly oblique chorus waves frequently occur in low‐density regions where fpe/fce≈3 ${f}_{\text{pe}}/{f}_{\text{ce}}\approx 3$. These waves exhibit an electric‐to‐magnetic energy ratio PE/c2PB>0.5 $\sqrt{{P}_{\mathrm{E}}/{c}^{2}{P}_{\mathrm{B}}} > 0.5$, much higher than the typical <0.1 ${

Global Model of Plasmaspheric Hiss from Multiple Satellite Observations

2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018
Gyroresonant wave particle interactions with plasmaspheric hiss play a fundamental role in the dynamics of the Earth's radiation belts and inner magnetosphere, affecting the loss of radiation belt electrons. Knowledge of the variability of the wave power
