Enhancing Thunderstorm Potential Area Detection over Northeast India Using INSAT series of Data: A Deep Learning Approach

This study introduces GeoConvNet, a deep learning framework that leverages multi-spectral INSAT satellite data to accurately detect and classify convective cloud structures over Northeast India, demonstrating strong correlation with rainfall and lightning observations while effectively addressing challenges posed by complex terrain through spatial buffering and terrain-based filtering.

Spatio-temporal assessment of PM2.5 and PM10 pollution in core and peripheral municipalities of the Kathmandu valley using regulatory and low-cost sensor data

By integrating regulatory and low-cost sensor data, this study reveals significant spatio-temporal air pollution disparities in the Kathmandu Valley, where urban core areas experience PM2.5 levels up to 1.6 times higher than peripheral zones due to local emissions and meteorological stagnation, highlighting the critical need for hybrid monitoring networks to address exposure inequality.

Natural and anthropogenic tipping points in a Mediterranean karstic lake: evidence from Lake Estanya (NE Spain)

This study reveals that Lake Estanya, a Mediterranean karstic lake, has experienced two distinct tipping points over the last 300 years—a natural hydroclimatic shift during the Little Ice Age and a recent anthropogenic eutrophication driven by intensive agriculture—demonstrating how the combined pressures of climate change and human activity are pushing these sensitive ecosystems into unprecedented states.

STACK Play Production Analysis – Canadian and Kingfisher Counties, Oklahoma: Production Performance, Flow Regime Characterization, and Parent-Child Well Interference. A Comprehensive Statistical Analysis of 3,550 Horizontal Wells

This study analyzes 3,550 horizontal wells in Oklahoma's STACK play to characterize production performance, flow regimes, and parent-child interference, concluding that effective infill development requires decline-corrected screening and formation-specific strategies rather than relying solely on parent well age.

Borealisation of an Arctic marine ecosystem during the Last Interglacial

This study uses sedimentary ancient DNA to demonstrate that the Last Interglacial triggered a "borealisation" of the Arctic marine ecosystem west of Svalbard, characterized by the invasion of temperate phytoplankton and megafauna driven by increased Atlantic water inflow, which likely reduced the region's capacity to sequester atmospheric carbon dioxide.

Anthropogenic warming shifted southwestern Europe into fire-weather conditions exceeding operational suppression thresholds

This study demonstrates that anthropogenic warming has shifted fire-weather conditions in southwestern Europe beyond operational suppression thresholds, significantly increasing the spatial extent and persistence of extreme wildfire events that render effective firefighting virtually impossible.

Predictive Landslide Susceptibility Modelling Using Statistical Approaches in Mantsa River catchment, Dawro Zone, South-western Ethiopia

This study evaluates landslide susceptibility in the Mantsa River Catchment of southwestern Ethiopia using Frequency Ratio and Logistic Regression models, identifying key conditioning factors such as land-use and lithology, and demonstrating that the Frequency Ratio model achieves slightly higher predictive accuracy (AUC = 0.874) to support risk reduction and sustainable land-use planning.

Seismotectonic aspects of the 2025 Kunar, Afghanistan, earthquake using field observations, InSAR and optical imagery

This study characterizes the seismotectonic aspects of the 31 August 2025 Mw 6.0 Kunar, Afghanistan earthquake, which caused significant damage and landslides via thrust faulting on the Kunar fault system, by integrating field observations with InSAR and optical imagery to reveal a complex, heterogeneous mainshock deformation field distinct from the more compact aftershock pattern.

Glacier tourism suitability on the Qinghai-Tibet Plateau: Future projections in response to climate change

This study employs the PLUS and XGBoost models to project future glacier tourism suitability on the Qinghai-Tibet Plateau under various climate scenarios, revealing a significant contraction of high-suitability zones by 2035 and highlighting the critical role of accessibility in guiding sustainable development strategies.
