Concrete and asphalt absorb the sun's energy so when a heatwave strikes city neighborhoods with few trees and lots of black pavement can get hotter than other areas a lot hotter fifteen eighteen degrees. Fahrenheit difference across the city at the same time. Be Shawna's Portland State University. Leads a heat mapping project funded by the National Oceanic and Atmospheric Administration over the last few summers? The project partnered with local groups in Washington DC Portland Oregon Boston and other cities. Volunteers used cars equipped with sensors that gather temperature and humidity data. Sean does and his team use that data to create digital maps showing how temperatures vary block by block. The hottest areas are often low income underserved. Neighborhoods Sean says. Getting residents involved in collecting data can help inspire local solutions. For example people may initiate tree planting projects targeted at the neighborhoods. That need them. Most the partnerships have been really instrumental in being able to get the communities together to convene them to go out and do this campaign and then to come back and start interpreting what it is that they're seeing ultimately what it is they can do about it
