A large recently completed mural painted with a surface-cooling coating on a building in Los Angeles may be a sign of things to come as cities face the challenges of a warming climate. Artists, community activists, urban planners and climate experts collaborated on the project. One of them was Ariane Middel, an assistant professor and urban climatologist in the Fulton Schools and the School of Arts, Media and Engineering. Using a thermal camera and a temperature-sensing robot, Middel measured the heat signature of the mural to demonstrate the cooling effects of the coating on the surrounding environment.
