GSI‐UNet: Extracting Geomagnetic and Solar Indices Features for Real‐Time Global Ionospheric Map Enhancement

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Real‐time Global Ionospheric Map (RT‐GIM) products, provided by the International GNSS Service (IGS), are designed to support time‐sensitive applications by offering ionospheric information with only a few minutes of latency. However, their accuracy falls far short of the high‐precision Final GIM, particularly during periods of intense solar ...

New Constraints on the Activity and Evolution of the Young Aigion‐Erineos Fault System, Gulf of Corinth, Greece

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Young active faults pose an underestimated seismic hazard as they can have limited geomorphic and structural expression. The Aigion‐Erineos fault system (AEFS) is a young normal fault on the south coast of the Gulf of Corinth, Greece that provides a key structural link with the Gulf of Patras.

Spatial and Temporal Evolution of Graben Formation During Rift Linkage Using Quantitative Geomorphology: Insights From Central Afar

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Quantifying fault slip rates and resolving rift segment linkage mechanisms is important for understanding the evolution of magma‐rich rift systems and the broader processes of continental break‐up. In tectonically and volcanically active rifts, such as Afar, there is commonly a lack of quantitative, observational constraints on long‐term fault

Interlinked Dynamics of Rice Cultivation Intensity and Ground Subsidence: Spatio‐Temporal Insights Into Water Resource Implications From Multi‐Year Spaceborne SAR Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Sustainable rice cultivation is vital to meet global food demands, particularly in regions relying on groundwater for irrigation. Over‐pumping, however, can cause significant ground subsidence, threatening both infrastructure and agricultural sustainability.

Time‐Varying Gravity Constraints on Groundwater Recharge and Managed Aquifer Strategies in Southern Taiwan

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Understanding groundwater recharge pathways is essential for designing effective managed aquifer strategies, yet in heterogeneous alluvial aquifers, these pathways are often uncertain and difficult to resolve with sparse well networks. We apply gravity as an independent constraint to quantify groundwater storage dynamics and evaluate recharge ...

Characterizing the Role of Storm‐Time High‐Latitude Ionospheric Structures in GPS Position Accuracy in Antarctica: May 2024 Storm

Space Weather, Volume 24, Issue 4, April 2026.
Abstract This study investigates the impact of high‐latitude ionospheric irregularities on global positioning system (GPS) position accuracy during the 10–11 May 2024 geomagnetic storm. Using data from ground‐based GPS receivers and an all‐sky camera in Antarctica, we examined evolution of GPS vertical total electron content, phase fluctuations, and ...

Understanding the Autonomous Electric Vehicle Cyber Threat Landscape: A Focus on Infrastructure, Threats and Ontology‐Based Modelling

Energy Internet, Volume 3, Issue 1, Page 39-51, April 2026.
ABSTRACT The development of autonomous electric vehicles (AEVs) represents the convergence of two simultaneous automotive revolutions: electric vehicles (EVs) and autonomous vehicles (AVs). AVs require sensors, decision‐making systems and actuation systems to achieve autonomous driving, whereas EVs require intelligent management and real‐time ...
