Evaluation‐Constrained Projections Reveal a Potentially Navigable Arctic by the 2030s

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract The rapid decline in Arctic sea ice thickness (SIT) is reshaping Arctic navigation prospects. However, large uncertainties in climate model skill hinder robust projections of future navigability. Here we evaluate SIT simulated by the CMIP6 using satellite, airborne, reanalysis, and in situ data sets across freezing and melting seasons.

Nightside Auroral Arcs Near the Electron Isotropy Boundary: TRACERS–THEMIS–MetOp Observations

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Particle precipitation is the ultimate driver of aurorae. Monoenergetic (∼keV) electrons accelerated above the ionosphere produce discrete auroral forms and are associated with field‐aligned currents that govern magnetosphere–ionosphere (MI) coupling.

Cross Correlation Between Plasmaspheric Hiss Waves and Enhanced Radiation Levels at Aviation Altitudes

Space Weather
Enhanced radiation in the Earth's atmosphere can pose serious hazards to pilots, aircraft passengers, and commercial space travelers. Recent results have shown, statistically, that there is a strong correlation between dose rates observed by Automated ...

The Mother’s Day Solar Storm of 11 May 2024 and Its Effect on Earth’s Radiation Belts

Universe
The month of May 2024 was characterized by solar energetic particles events directed towards the Earth, especially the big event causing a strong terrestrial geomagnetic storm during the night from 10 to 11 May 2024, with auroras observed everywhere in ...

A Low Cost, Fully Sensorless Dual Axis PV Tracker Using Astronomical Ephemerides and Discrete Actuation

Energy Technology, Volume 14, Issue 11, November 2026.
A fully sensorless dual‐axis solar tracker based on astronomical ephemerides and postal‐code geographic localization is developed and validated. The proposed discrete tracking strategy increases photovoltaic energy yield while minimizing actuator energy consumption, hardware complexity, and maintenance requirements, providing a practical and cost ...

Empirical Parameterizations of ULF Power and Drift Orbit Averaged Radial Diffusion Coefficients From Ground Magnetometers for Different MLT

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Radial diffusion, driven by ultra‐low frequency (ULF) waves, is an important process for the transport of electrons in the outer radiation belt. Ground magnetometers give us constant observations of such ULF waves but their usefulness is limited by the models used to transform ground measurements into their progenitor fields in space.

Hysteretic Dynamics of Stream Network Expansion and Contraction Revealed Through High‐Resolution Integrated Hydrological Modeling

Water Resources Research, Volume 62, Issue 11, November 2026.
Abstract As landscapes cycle through wetting and drying, stream networks expand and contract, driving material export and biogeochemical transformations with important implications for water quality and ecosystem function. Because it is challenging to measure the extent (L) $(L)$ of the active network, streamflow (Q $Q$) is often used as a proxy ...

An Investigation of the Characteristics of Indian Summer Monsoon Low‐Pressure Systems Under Stratospheric Aerosol Geoengineering

Earth's Future, Volume 14, Issue 11, November 2026.
Abstract Monsoon Low‐Pressure Systems (LPSs) that govern the rainfall of the Indian Summer Monsoon (ISM) contribute more than half of its rainfall and extreme rainfall events. In this study, we explore how LPS activity changes under greenhouse warming and Stratospheric Aerosol Intervention (SAI) using simulations from the fully coupled CESM2.1.3 ...

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.
