Evaluating urban water body cooling effects and exposure at high spatial resolution: A case study in Guangzhou

Key Points

• The study reveals significant cooling effects from urban water bodies in Guangzhou's climate zones, enhancing thermal comfort.
• Cooling temperatures reached up to 4 degrees Celsius near these bodies, with implications for urban planning.
• Observational analysis focused on high spatial resolution data across Guangzhou's diverse urban landscape, measuring temperature variations.
• Findings suggest urban water bodies can serve as vital climate adaptation features, but further studies are needed to confirm broader applicability.
