Sensitivity of Nocturnal Low‐Level Jet Representation to Model Resolution and Boundary Layer Schemes: Implications for Wind Energy Assessment Over Saudi Arabia

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Sensitivity tests on low‐level wind speeds and stability associated with the diurnal cycle of convective boundary layer (CBL) are performed using five Weather Research and Forecasting (WRF) Model simulations over the Riyadh, Saudi Arabia region.

Modelling soil dust aerosol in the Bodélé depression during the BoDEx campaign [PDF]

, 2006
We present regional model simulations of the dust emission events during the Bodélé Dust Experiment (BoDEx) that was carried out in February and March 2005 in Chad. A box model version of the dust emission model is used to test different input parameters

Inhomogeneous Dust Biases Photometric Redshifts and Stellar Masses for LSST

The Astrophysical Journal Letters
Spectral energy distribution (SED) modeling is one of the main methods to estimate galaxy properties, such as photometric redshifts, z , and stellar masses, M _* , for extragalactic imaging surveys.

Spherical nonthermal pulsational mode stability thermo-statistically moderated with extra-negative ions

Fundamental Plasma Physics
The presence of diverse negative ions is well-known to modify different collective waves and instabilities in diverse space and astrophysical environments.

Quantifying Water Ice in Regolith Mixtures via Infrared (1.2–2.5 μm) Reflectance Model Parametrization

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Water ice deposits occur on inner solar system bodies in sunlit and shadowed terrains. We develop approaches to remotely determine the mixing mode with regolith (areal vs. intimate), ice grain size, and abundance that reveal processes of ice formation, emplacement, and evolution.

Theoretical Determination of the Binding Energies of Methanol and Related Species onto Amorphous Solid Water Ice

The Astrophysical Journal
The formation and survival of complex organic molecules (COMs) in cold interstellar environments depends on their interactions with icy dust grain surfaces.

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Experimental Aeolian Abrasion of Basalt Sands as an Analog for Producing Martian Dust

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Dust covers a significant portion of Mars' surface, with dust storms periodically engulfing the planet. Despite this, the origins of Martian dust are poorly understood, especially for ancient dust deposits. To address this deficit, we conducted experiments to replicate the mechanical abrasion of saltating sand grains in a Martian desert dune ...
