Project: Investigating nitrate-initiated secondary organic aerosol formation in the laboratory and in Colorado Front Range forestsJuliane Fry is an assistant professor of chemistry and environmental studies at Reed College, in Portland, Oregon. Fry’s research focuses on atmospheric chemistry, aerosol formation, and air pollution. She is investigating the source of particulate hazes—dirty-looking, low-visibility air filled with microscopic particles—that form in forests downwind of industrial and urban centers. These tiny atmospheric particulates are important to public health because they are linked to asthma and cardiac disease. While scientists know that nitrogen oxide gases—emitted from such sources as coal and fossil-fuel combustion—initiate the particulate formation, they don’t fully understand which nitrates and reaction mechanisms are involved. Working with Fred Fehsenfeld, Steve Brown, Jose-Luis Jimenez, Doug Day, and Jim Smith, Fry will assemble a group of instruments capable of measuring various species of nitrates and particulate size. They will then monitor pollution plumes flowing into the Manitou Forest Observatory, near Woodland Park, Colorado, and also conduct chamber experiments at NCAR to pinpoint the responsible agents. Successful results would assist policy makers in developing strategies to reduce haze. Fry is looking forward to exchanging the slushy snow of the West Coast for Colorado powder. “After only skiing in mashed potatoes in California and Oregon, I can't wait to see what real snow feels like,” she says.
