Scientists Plan Study of Northern Cities’ Air Quality
![Ice fog obscures the view in front of the Geophysical Institute on the University of Alaska Fairbanks campus. Ice fog forms when water in the air becomes supercooled, which occurs around minus 40 degrees Fahrenheit; however, the polluted Fairbanks air allows water droplets to freeze at temperatures as warm as minus 31.

Atmospheric scientists at the University of Alaska Fairbanks have launched an effort to better understand urban air quality problems in northern cities. During the next few years, Bill Simpson and Jingqiu Mao of UAF’s Geophysical Institute hope to join international researchers on a large-scale field study to understand the chemistry behind air pollutants in Arctic […]
