A Self‐Supervised Seasonal Anomaly Embedding ViT for Label‐Free Drought Mapping in the Horn of Africa

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Drought poses a major threat to agriculture and food security in the Horn of Africa (HOA), where monitoring efforts are hindered by sparse in situ observations and a lack of ground truth data. In this paper, a new self‐supervised drought classification model, Seasonal Anomaly Embedding with Vision Transformers (SAED‐ViT) is proposed using ...

Palagonitization of Volcanic Rocks in Polar Climates: The Case of Deception Island (Antarctica)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract A detailed study of palagonitization in rocks from Deception Island—one of Antarctica's most active volcanoes—has been performed to advance our understanding of this alteration process. A detailed petrographic (optical and SEM), mineralogical (XRD), and mineral and glass spot geochemistry (EDS and EMP) characterization has been conducted on ...

Thermospheric Nitric Oxide Density From SABER: Local Time Dependence and Validation Against Independent Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.
Abstract The Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) nitric oxide (NO) concentration is a newly derived data set from SABER NO emission rate measurements, covering altitudes from 120 to ∼250 km with full local time coverage.

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...
