Google Research has expanded its AI-driven dataset of building-level rooftop reflectivity to over 50 global cities. This initiative aims to help urban planners implement cool-roof solutions to combat extreme heat and the urban heat island effect. The new dataset, detailed in a Nature Communications paper, utilizes a novel methodology that fuses satellite imagery with machine learning to provide high-resolution reflectivity data, enabling targeted interventions that could mitigate urban heat by up to 0.5°C globally.
