Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests
Measurements of aerosol composition, volatile organic compounds, and CO are used to determine biogenic secondary organic aerosol (SOA) concentrations at a rural site 70 km north of Toronto. These biogenic SOA levels ...
The hygroscopicity parameter (kappa) of ambient organic aerosol at a field site subject to biogenic and anthropogenic influences: relationship to degree of aerosol oxidation
Cloud condensation nuclei (CCN) concentrations were measured at Egbert, a rural site in Ontario, Canada during the spring of 2007. The CCN concentrations were compared to values predicted from the aerosol chemical ...
Photochemical processing of organic aerosol at nearby continental sites: contrast between urban plumes and regional aerosol
As part of the BAQS-Met 2007 field campaign, Aerodyne time-of-flight aerosol mass spectrometers (ToF-AMS) were deployed at two sites in southwestern Ontario from 17 June to 11 July 2007. One instrument was located at ...
Diurnally resolved particulate and VOC measurements at a rural site: indication of significant biogenic secondary organic aerosol formation
We report simultaneous measurements of volatile organic compound (VOC) mixing ratios including C-6 to C-8 aromatics, isoprene, monoterpenes, acetone and organic aerosol mass loadings at a rural location in southwestern ...
Slower CCN growth kinetics of anthropogenic aerosol compared to biogenic aerosol observed at a rural site
Growth rates of water droplets were measured with a static diffusion cloud condensation chamber in May-June 2007 at a rural field site in Southern Ontario, Canada, 70 km north of Toronto. The observations include periods ...
