Urban Heat Hotspots in Tarragona: LCZ-Based Remote Sensing Assessment During Heatwaves

Atmosphere
Heatwaves are intensifying across Mediterranean cities, where the Urban Heat Island (UHI) effect amplifies thermal stress. This study updates the spatial characterization of the Surface Urban Heat Island (SUHI) in Tarragona using multi-sensor remote ...

Spatiotemporal variation of urban thermal environment and its relationship with urban expansion types from 2000 to 2020: a case of Huai’an central urban area, Huai’an, China

Geomatics, Natural Hazards & Risk, 2022
It is critically important to understand the variation of urban thermal environment since urban heat island (UHI) effect is one of the most worrisome urban environment and impedes urban sustainable development.

Urban Shrinkage and Surface Urban Heat Islands: Does Population Decline Lead to Cooling? A Spatiotemporal Analysis of China's 89 Shrinking Cities (2001–2019)

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Numerous studies have examined how urban expansion exacerbates Surface Urban Heat Island intensity (SUHII), yet limited attention has been paid to whether and how urban shrinkage mitigates SUHII. This study employed multiple models to analyze the spatiotemporal evolution of surface urban heat island (SUHI) and its driving factors in 89 ...

Abiotic Drivers of Groundwater Fauna Across Aquifer Types and Urban–Rural Gradients in the City of Halle (Saale), Germany

Ecohydrology, Volume 19, Issue 5, July/August 2026.
ABSTRACT Subterranean ecosystems in urban environments are exposed to multiple anthropogenic stressors that compromise groundwater quality and biodiversity. Rising groundwater temperatures, oxygen depletion, hydraulic disturbance and chemical contamination are among the main pressures.

Investigating Surface Urban Heat Island (SUHI) Effect for a Hill City

Abstract Urban Heat Island (UHI) along with Climate Change has created a new challenge for Urban Planners in terms of environmental sustainability. In composite climate its effect will be, ‘decrease in outdoor activity’ by urban dwellers and ‘surge in energy demand’ for thermal comfort.

Quantifying urban tree canopy cooling capacity using Bayesian hierarchical models and satellite imagery

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 338-352, January 2026.
Cities are getting hotter because of climate change and urban development, increasing risks to health and well‐being. We analyzed how increasing urban tree canopy cover in city areas of 900 m2 can reduce land surface temperatures, using detailed aerial‐LiDAR and satellite data with Bayesian hierarchical models.

Urban Heat Intensification and Heatwave Trends in Hanoi and Ho Chi Minh City, Vietnam

Advances in Meteorology, Volume 2026, Issue 1, 2026.
Rapid urbanization combined with climate variability has intensified extreme heat exposure in tropical Vietnam. Using multi‐decadal ground observations (1981–2022), ERA5 reanalysis, and Landsat‐derived land surface temperature (LST), this study investigates long‐term trends of heatwaves and surface urban heat island (SUHI) intensity in Hanoi and Ho Chi
