Elucidating determinants of aerosol composition through particle-type-based receptor modeling
(2011)
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 ...
Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests
(2010)
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 ...
Aerosol composition and sources in the central Arctic Ocean during ASCOS
(2011)
Measurements of submicron aerosol chemical composition were made over the central Arctic
Ocean from 5 August to 8 September 2008 as a part of the Arctic Summer Cloud Ocean Study
(ASCOS) using an aerosol mass spectrometer ...
The effect of meteorological and chemical factors on the agreement between observations and predictions of fine aerosol composition in southwestern Ontario during BAQS-Met
(2011)
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 ...
Diurnally resolved particulate and VOC measurements at a rural site: indication of significant biogenic secondary organic aerosol formation
(2011)
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
(2010)
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 ...
Closure between measured and modeled cloud condensation nuclei (CCN) using size-resolved aerosol compositions in downtown Toronto
(2006-06)
Measurements of cloud condensation nuclei (CCN) were made in downtown Toronto during
August and September, 2003. CCN measurements were performed at 0.58% supersaturation
using a thermal-gradient diffusion chamber, whereas ...
