Temperature data, traditionally available either at the treetop or rooftop level, does not always accurately reflect human exposure. This project provided ground-level data to understand how the built environment influences temperatures felt across different neighborhoods. Ground-level data is important because it more accurately represents what people feel when they are working, playing or exercising outside. CAPA Strategies also applied the data collected to model morning, afternoon and evening temperatures. The data is available at www.H3AT.org.
