Researchers have developed a new framework to analyze the differences between land surface temperature (LST) and human-centric heat stress metrics like the Universal Thermal Climate Index (UTCI). Using machine learning models such as geographically weighted XGBoost and generalized additive models, the study revealed significant spatial variations in how urban morphology impacts these thermal measures. The findings indicate that LST inadequately represents actual human heat stress, particularly concerning factors like sky view and albedo, which are crucial for effective urban planning and heat risk management.
