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 hygroscopicity parameter (kappa) of ambient organic aerosol at a field site subject to biogenic and anthropogenic influences: relationship to degree of aerosol oxidation
(2010)
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
(2011)
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 ...
Particle formation and growth at five rural and urban sites
(2010)
Ultrafine particle (UFP) number and size distributions were simultaneously measured at
five urban and rural sites during the summer of 2007 in Ontario, Canada as part of the
Border Air Quality and Meteorology Study ...
Cloud condensation nuclei closure study on summer arctic aerosol
(2011)
We present an aerosol - cloud condensation nuclei (CCN) closure study on summer high
Arctic aerosol based on measurements that were carried out in 2008 during the Arctic
Summer Cloud Ocean Study (ASCOS) on board the ...
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 ...
