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 ...

Soft Proton Environment Modeling for SMILE Using XGBoost and Solar Cycle–Informed Synthetic Data Sets

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Soft proton contamination presents a persistent threat to the performance of space‐based X‐ray observatories such as ESA's upcoming Solar‐wind Magnetosphere Ionosphere Link Explorer (SMILE). This study develops a machine‐learning framework for modeling soft proton fluxes in the 92.2–159.7 keV range, tailored to SMILE's elliptical, highly ...

New Observations of Cosmic Noise Absorption in the South American Magnetic Anomaly (SAMA) Using a Next‐Generation Riometer

Space Weather, Volume 24, Issue 7, July 2026.
Abstract This study reports the first observations of cosmic noise power (CNP) and cosmic noise absorption (CNA) obtained with a next‐generation riometer installed at the Southern Space Observatory (SSO/INPE) in Brazil, located within the South American Magnetic Anomaly (SAMA).

Supporting Informed Shutter Operations for SMILE's SXI Using Ensemble Classifiers for Soft Proton High Flux Period Predictions

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Satellite X‐ray imagers are highly vulnerable to contamination by soft protons (∼100 keV), which can trigger spurious charge‐coupled device events and force interruptions in observations. For XMM‐Newton, such contamination reduced usable science time by ∼40%.

QEUV vs. Other EUV Proxies: A Re‐Evaluation of Solar EUV Proxies for Thermospheric and Space Weather Investigations

Space Weather, Volume 24, Issue 7, July 2026.
Abstract F10.7, Mg II, and F30 are widely used proxies for variability in solar Extreme UltraViolet (EUV, 5–120 nm) irradiance. An alternative proxy for solar EUV variability is QEUV, an indirect measure of total solar EUV irradiance, retrieved from observations of Earth's Far UltraViolet (FUV, 120–300 nm) airglow and from empirically modeled solar EUV

Contrasting Space Weather Drivers of Two Geomagnetically Induced Current Events in Alberta, Canada During the May 2024 Superstorm

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Strong geomagnetic disturbances (GMDs) caused by intense space storms induce geomagnetically induced currents (GICs) in the Earth and within long conductive infrastructure, potentially posing risks to electricity transmission systems. Here, we investigate the solar wind conditions and magnetospheric processes responsible for two significant ...
