This dataset corresponds to observations at the PROPHET ( Program for Research on Oxidants: PHotochemistry, Emissions, and Transport) tower in July 2014. The tower is located within the forested University of Michigan Biological Station (UMBS) near Pellston in northern Michigan (Gunsch et al. 2018). Long-range aerosol transport affects locations hundreds of kilometers from the point of emission, leading to distant particle sources influencing rural environments that have few major local sources. Source apportionment was conducted using the real-time aerosol chemistry measurements made at the UMBS station, a site representative of the remote forested Great Lakes region. Size-resolved chemical composition of individual 0.5–2.0 µm particles was 10 measured using an aerosol time-of-flight mass spectrometer (ATOFMS), and non-refractory aerosol mass less than 1 µm (PM1) was measured with a high-resolution aerosol mass spectrometer (HR-AMS). The field site was influenced by air masses transporting Canadian wildfire emissions and urban pollution from Milwaukee and Chicago.
