Forecasting Equatorial Plasma Bubbles From Precursor TEC Signatures Observed by C/NOFS

Space Weather, Volume 24, Issue 1, January 2026.
Abstract This study investigates the potential of localized total electron content (TEC) perturbation measurements, possibly associated with bottomside upwelling of the F‐layer, as precursors for forecasting ionospheric plasma irregularities, particularly the equatorial plasma bubbles (EPBs).

Structural Controls on Splay Fault Rupture Dynamics During Cascadia Megathrust Earthquakes

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within the accretionary wedge. The mechanics of these shallow rupture phenomena and their dependence

Efficient Sampling of Geophysical Sensor Arrays on the Seafloor

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The great expense of deploying dense arrays of seafloor sensors for continuous collection of geophysical data inhibits the proliferation of measurement systems to the majority of the planet's surface. Advancing geophysical coverage offshore will require technologies different from conventional methods applied onshore where electrical power and

In Situ Measurements of Ice and Snow Emissivity in the Far‐Infrared

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract This paper describes the first field deployment of the Far INfrarEd Spectrometer for Surface Emissivity far‐infrared Fourier transform spectrometer to an Arctic environment and shows retrievals of the emissivity of ice and snow in the wavenumber range 400–1,200 cm−1 at viewing angles of 35° and 50°.

Tidally Driven Wavenumber‐3 and ‐4 Structures in the Ionosphere‐Thermosphere Observed by ICON and Comparison of Their Coupling Mechanisms

Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract We analyze fixed local time, longitudinal wavenumber‐3 (WN3) and wavenumber‐4 (WN4) structures in the low‐latitude F‐region ionosphere using ICON‐IVM observations of ion drifts, temperatures, and densities from Jan 2020 to Jun 2022. These ionospheric wave patterns are compared to non‐migrating tides and stationary planetary waves in the ...

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

Artificial Intelligence Weather Radar

Radio Science, Volume 60, Issue 12, December 2025.
Abstract The integration of artificial intelligence (AI) with weather radar systems marks a transformative advancement in remote sensing. This study introduces an AI‐powered radar system that utilizes Long Short‐Term Memory (LSTM) neural networks to predict the in‐phase (I) and quadrature (Q) components of radar signals, enabling faster, and more ...

Feasibility of strong diffusion encoding and fast readout using a plug‐and‐play head gradient insert at 7 T

Magnetic Resonance in Medicine, Volume 94, Issue 5, Page 2304-2316, November 2025.
Purpose Diffusion weighting is achieved by the application of external field gradients typically for tens of milliseconds, during which the signal also substantially decays due to inherent T2 relaxation. Employing strong gradients will shorten the echo time (TE) and increase the signal‐to‐noise ratio.

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten

physica status solidi (b), Volume 262, Issue 11, November 2025.
This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

First Detection of [SI] in Near‐IR JWST Observations of Io in Eclipse, and Comparison With SO Emissions, Evolving Volcanic Eruptions, and Prior UV HST‐STIS [SI] Emissions

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract We observed Io with the James Webb Space Telescope (JWST) NIRSpec/Integral Field Unit (1.0–5.3 μm, R∼2700 $R\sim 2700$) in August 2023 while the satellite was in eclipse. Thermal emission from Kanehekili Fluctus is consistent with the cooling of lava flows after a vigorous eruption in November 2022.
