Urban Heat Island
ROANOKE, Va. – Just last year, the city of Roanoke was part of a study to learn more about urban heat islands within the city and what can be done to improve it.
You might be wondering what urban heat islands is. It occurs in areas where buildings and asphalt cause temperatures to run 15-20° warmer in urban areas versus rural areas nearby.
The National Integrated Heat Health Information System (HIHHIS) along with many other organizations have designed special sensors that are mounted onto cars and bikes of volunteer scientists. These volunteers were given specific routes to travel three times a day. The temperature, humidity and precise location of the sensor were recorded every second along the route.
