New study analyzes air quality impacts of wildfire smoke

Desert Research Institute
Peer-Reviewed Publication

With wildfires increasing in frequency, severity, and size in the Western U.S., researchers are determined to better understand how smoke impacts air quality, public health, and even the weather. As fires burn, they release enormous amounts of aerosols — the vaporized remains of burning trees and homes that enter the atmosphere and the air we breathe. Now, a new study dissects these aerosols and gases to pinpoint their potential effects on our health as well as the planet’s short and long-term weather.
