NOAA selected 17 communities in the US and one community in Santiago, Chile to participate in the Urban Heat Island mapping campaign. The campaign was part of the Biden-Harris Administration’s Justice40 and America the Beautiful initiatives. NOAA worked in collaboration with CAPA Strategies LLC to develop each communities’ unique urban heat island profile, which enables the communities to identify “equitable ways to implement [local] cooling solutions.” NOAA selected 2023’s communities in part due to their expressed commitments to addressing the environmental justice implications of these urban heat islands on the most vulnerable populations.
