This dataset corresponds to observations at PROPHET in July 2014, as described in Gunsch et al. 2018, Atmospheric Chemistry & Physics.
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 5 conducted using real-time aerosol chemistry measurements made in July 2014 at the forested University of Michigan Biological Station near Pellston, Michigan, 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 ur15 ban pollution from Milwaukee and Chicago.
Atmospheric trace gas and particulate matter chemistry were measured at PROPHET in July 2014 to improve our understanding of aerosol source contributions in the upper midwest US.
Air was sampled from 34 m a.g.l.
