People in urban areas are at higher risk during heat waves, but NASA data shows how parks and green spaces are cooler than the surrounding areas.
This image shows how asphalt and concrete trap heat. The purple and red areas are surfaces that are hotter than 130℉ (54℃). Yellow areas are slightly cooler but still very hot. Some roads and sidewalks got so hot that a few seconds of skin contact could result in second degree burns.
This image shows mid-day conditions in Phoenix, AZ on June 19, 2024. It was measured by a NASA instrument called ECOSTRESS, which is aboard the @iss. Data from Landsat and Sentinel-2 helped improve the resolution so that differences can be seen across a smaller area.
Information like this can help people and communities plan ways to stay safer in the heat.
Image Descriptions:
1: Text reads “Urban Heat Seen From Space” in white at the center of the image with a yellow, red, and purple bar underneath. In the background is a map of urban heat risk in Phoenix.
2: A map of the Phoenix area, where asphalt and concrete surfaces are outlined in yellow, red, or purple lines depending on the surface temperature. Purple represents the hottest. The left side of the image is mostly purple and the right side is mostly red. Several park areas and green spaces have yellow (cooler) surface temperatures. A key at the bottom of the image correlates color to surface temperature and thermal burn risk.
3: The same map of the Phoenix area, but zoomed in over Encanto to highlight areas around green spaces, which are mostly yellow.
