Phoenix Cool Pavement Heat Exposure Metrics

This mission includes datasets of heat exposure metric fieldwork days as part of the City of Phoenix Cool Pavement Evaluation project in 2020-2021 to evaluate the different heat metrics (air, surface, and mean radiant temperature) of a reflective pavement coating that was applied to the streets of eight residential neighborhoods. Two mobile measurement types were used to gather the data. A mobile biometeorolgical cart, MaRTy, which measures air, surface, and mean radiant temperature as well as relative humidity, wind speed, and the geolocation. The MaRTy cart can measure at specific locations and move between locations within a given time. Additionally, a vehicle was equipped with t-type thermocouples and an infrared radiometer to measure 2-m air temperature and the surface temperature of the road within the whole neighborhood measuring both reflective pavement and regular asphalt concrete roads.
