On August 7, 2020, roughly 80 community scientists in Houston and Harris County took to the streets with specially-designed thermal sensors attached to their cars or bicycles. They embarked on a 300-square-mile effort to measure and map urban heat in the region.

This community science endeavor is led by the Houston Harris Heat Action Team (H3AT), a collaboration between Houston Advanced Research Center (HARC), the City of Houston, and Harris County Public Health (HCPH), and The Nature Conservancy in Texas.


The data collected as part of the Heat Watch mapping project will inform future climate mitigation strategies and interventions, ensuring they are located in the urban “hot spots” that need them most.
