UMBS: PROPHET Aerosol and Ozone Data, July 2014

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.
