Short summary

Fairbanks, Alaska experiences episodes of high concentrations of PM_2.5 pollution in the wintertime. The sources and mixing ratios of gas-phase pollution, and the extent to which it affects the formation of PM_2.5, are not well understood. Here, we examine the sources of gas-phase species measured in wintertime Fairbanks. We compare these results with other PM_2.5 measurements to determine how various sources can affect the formation of PM_2.5 pollution.
