Nearly 50 scientists from the U.S. and Europe descended on Fairbanks recently to study the sources of air pollution and how the contaminants interact in the city’s cold and dark climate.
This Feb. 16, 2022, photo shows a plume of smoke being emitted into the air from a power plant in Fairbanks, Alaska, which has some of the worst polluted winter air in the United States. Over seven weeks this winter, nearly 50 scientists from the continental U.S. and Europe descended on Fairbanks to study the sources of air pollution.
What they find could help city planners make better decisions on where to place power plants or smelters in northern climates and guide lawmakers on how to regulate chemicals in fuel oil or other sources to reduce the harm. This Feb. 21, 2022, photo provided by the University of Alaska Fairbanks Geophysical Institute shows Swiss team members working with a tethered balloon and payload used to measure different characteristics of aerosols and trace gases in the atmosphere over Fairbanks, Alaska. Over seven weeks this winter, nearly 50 scientists from the continental U.S. and Europe descended on Fairbanks to study the sources of air pollution.
Owen Hanley practiced pulmonary medicine in Fairbanks for about 35 years. The retired doctor says the air pollution problem in Fairbanks can permanently harm respiratory function and cause many other problems. Seven French teams made detailed measurements of the air in downtown Fairbanks in efforts to better understand how small particles and droplets are formed. Meanwhile, a Swiss team used a tethered balloon, equipped with specialized instruments, to measure characteristics of aerosols and different trace gases at 1,200 feet above the ground. Another instrument allowed them to measure vertical profiles of the atmosphere.
Another goal of the research came from members of the Fairbanks community: People wanted to know what the air is like inside their homes.
