Cooling Performance: Exploring the Heat Mitigation Effect of Urban Trees with Computer Vision

Rising summer temperatures are placing increasing pressure on many cities to adapt public spaces for heightened heat stress. While the cooling benefits of urban trees are well documented, there remains a limited understanding of how these effects vary across tree types, morphologies, and urban contexts. This study addresses this knowledge gap by employing computer vision techniques to analyze thermal imagery of urban trees in four climatically diverse cities: Amsterdam, Boston, Dubai, and Los Angeles. Our findings reveal significant variation in cooling performance attributable to genera-specific traits, water consumption properties and surrounding environmental factors. By initiating a comparative analysis of urban tree types and their thermal performance, this research provides a foundation for more targeted and climate-responsive urban greening policies.
