Abstract On an annual basis, heat is the chief cause of weather-related deaths in United States. Therefore, understanding temperature structure where people live important for reducing health burden imposed by hot weather. This study focused on air temperatures Detroit, Michigan, metropolitan region during summer 2009. An observational network was established that included 1) monitors sited backyards residential participants, 2) National Weather Service standard observations, and 3) a operated State Michigan. Daily high low were analyzed spatial pattern, magnitude variability, relationships with weather conditions. The existence variability confirmed specifically considered to be dangerous public health. between observations distance water, city center, local percent impervious surface investigated. daily typically stronger pattern more consistent than those high. largest correlation land-cover location attributes values temperatures. most correlated water. Consistent previous studies urban environments, results suggest need sensitivity spatially variable nature exposure events both planning. For example, these showed downtown area experienced elevated nights eastern portions Detroit decreased afternoons.
