Analysis of urban microclimate acoustic tomographic heatmaps

In this work, acoustic tomography is employed as a technique for monitoring urban microclimate variables and mapping temperature distributions in urban street canyons, focusing on identifying and analyzing Urban Heat Island (UHI) hot spots. The microclimate temperature, wind profiles, and urban morphology are exciting, as they influence intra-urban characteristics and contribute to UHI effects. The acoustic tomographic heatmap provides street-level resolution and detailed insights into spatial temperature deviations, including minor acoustic time delays associated with faster sound speeds and higher temperatures, characteristic of UHI hot spots within urban street canyons. Preliminary results of UHI hot spots in Washington, D.C., during a heat wave will be discussed.
