Summary: Urban heat islands occur in areas containing more impervious surfaces and fewer natural environments. The day and night surface temperature is higher in urban heat islands than in surrounding areas. During heat waves, this can lead to greater numbers of heat-related illnesses and deaths. Landsat satellites collect data on surface temperature and vegetative change that can help cities mitigate the heat stresses for residents, especially in a warming climate. For this episode of Eyes on Earth, we hear about how a mapping project involving Landsat data helped the New York City Council identify urban heat islands.

Guests: Dr. Christian Braneon, a remote sensing specialist at NASA’s Goddard Institute for Space Studies, and James Cottone, a New York City Council resiliency planner
