Optimizing Hybrid Wind–Solar Systems in Barren Land Under Constraints Imposed by Atmospheric Aerosols

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract By using a solar photovoltaic (PV) performance model and applying it to global data from 2000 to 2022, we demonstrated that although the net impact of aerosols on power generation was negative, this loss was almost entirely driven by soiling of panel surfaces and could be mitigated by developing an appropriate cleaning regime.

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 ...

Mesoscale Modeling of Titan’s Shangri‐La Region: The Impact of Surface Properties on Winds

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The knowledge of Titan’s near‐surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest active near‐surface dynamics. The Dragonfly rotorcraft lander will fly close to the surface in the Shangri‐La region, near the Huygens landing site, where complex dune ...

Exploring Future Ecogeomorphic State Transitions of an Undeveloped Barrier Island: Multidecadal Model Projections for North Core Banks, NC, USA

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Ecogeomorphic state transitions in coastal barrier systems will be impacted and likely amplified by projected accelerated sea‐level rise and enhanced storm intensity over the next several decades. When, where, and how these transitions will take place remain uncertain and complex, yet are of primary interest to coastal managers looking to ...

Fluvially Sourced Sediment Supply and Climate Modulate Morphodynamics and State Transitions in Bistable Aeolian Dunefields

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Alternative stable state theory in aeolian geomorphology describes the occurrence of bare and vegetated aeolian dunes in response to long‐term climatic and ecological drivers. Transitions between states, as well as their co‐occurrence (bistability), can arise from perturbations to drivers, disturbance, and associated biophysical feedbacks ...

Internal anatomy of an erg sequence from the aeolian-fluvial system of the De La Cuesta Formation (Paganzo Basin, northwestern Argentina)

Geologica Acta, 2011
Permian red beds of the De La Cuesta Formation in the Sierra de Narváez (Paganzo Basin, northwestern Argentina) are essentially composed of sandstones associated with mudstones and subordinate conglomerates.

Frequency‐Domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Ground Penetrating Radar Observations of Subsurface Structures From the Makgadikgadi Pans (Botswana): A Terrestrial Analogue of Martian Playa Lakes

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Playa lakes are considered promising landing sites on Mars because of their strong astrobiological potential. Therefore, sediments and buried structures in terrestrial playa lakes have become the focus of numerous analogue studies. The inclusion of ground penetrating radar (GPR) in the payloads of Martian missions has opened new avenues for ...

Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon. Their mechanical properties are critical for understanding the evolution of Titan's geomorphology and crustal layering.
