Diurnally resolved particulate and VOC measurements at a rural site: indication of significant biogenic secondary organic aerosol formation
Sjostedt, S. J., J. G. Slowik, J. R. Brook, R. Y. -W Chang, et al. 2011. "Diurnally resolved particulate and VOC measurements at a rural site: indication of significant biogenic secondary organic aerosol formation." Atmospheric Chemistry and Physics 11(12): 5745-5760.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 ... -
The effect of meteorological and chemical factors on the agreement between observations and predictions of fine aerosol composition in southwestern Ontario during BAQS-Met
Markovic, M. Z., K. L. Hayden, J. G. Murphy, P. A. Makar, et al. 2011. "The effect of meteorological and chemical factors on the agreement between observations and predictions of fine aerosol composition in southwestern Ontario during BAQS-Met." Atmospheric Chemistry and Physics 11(7): 3195-3210.The Border Air Quality and Meteorology Study (BAQS-Met) was an intensive, collaborative field campaign during the summer of 2007 that investigated the effects of transboundary pollution, local pollution, and local ... -
Elucidating determinants of aerosol composition through particle-type-based receptor modeling
McGuire, M. L., C. -H Jeong, J. G. Slowik, R. Y. -W Chang, et al. 2011. "Elucidating determinants of aerosol composition through particle-type-based receptor modeling." Atmospheric Chemistry and Physics 11(15): 8133-8155.An aerosol time-of-flight mass spectrometer (ATOFMS) was deployed at a semi-rural site in southern Ontario to characterize the size and chemical composition of individual particles. Particle-type-based receptor modelling ... -
Photochemical processing of organic aerosol at nearby continental sites: contrast between urban plumes and regional aerosol
Slowik, J. G., J. Brook, R. Y-W Chang, G. J. Evans, et al. 2011. "Photochemical processing of organic aerosol at nearby continental sites: contrast between urban plumes and regional aerosol." Atmospheric Chemistry and Physics 11(6): 2991-3006.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 ...
