Carbon dioxide levels are rising across wide swaths of the Arctic Ocean's Canada Basin（图）
Carbon dioxide levels rising across wide swaths Arctic Ocean Canada Basin
2020/7/10
Melting of Arctic ice caused by climate change has exposed more sea surface to the atmosphere. Scientists have long suspected this trend would increase carbon dioxide in Arctic Ocean waters.Now U...
Quantitative assessment of upstream source influences on total gaseous mercury observations in Ontario, Canada
upstream source total gaseous mercury Ontario, Canada
2011/2/25
Hourly total gaseous mercury (TGM) concentrations at three monitoring sites (receptors) in Ontario were predicted for four selected periods at different seasons in 2002 using the Stochastic Time-Inver...
Baseline levels and trends of ground level ozone in Canada and the United States
Baseline levels and trends ground level ozone Canada the United States
2010/9/21
A statistical method was developed to extract baseline levels of ground level ozone in Canada and the US, and to quantify the temporal changes of baseline ozone levels on annual, seasonal, diurnal and...
Trans-Pacific transport of reactive nitrogen and ozone to Canada during spring
Trans-Pacific reactive nitrogen ozone Canada spring
2010/9/21
We interpret observations from the Intercontinental Chemical Transport Experiment, Phase B (INTEX-B) in spring 2006 using a global chemical transport model (GEOS-Chem) to evaluate sensitivities of the...
Identification of potential regional sources of atmospheric total gaseous mercury in Windsor, Ontario, Canada using hybrid receptor modeling
potential regional sources atmospheric total gaseous mercury hybrid receptor modeling
2010/8/16
Windsor (Ontario, Canada) experiences trans-boundary air pollution as it is located on the border immediately downwind of industrialized regions of the United States of America. A study was conducted ...
Long range transport of mercury to the Arctic and across Canada
Long range transport mercury the Arctic Canada
2010/8/16
This study is the most extensive study to date on the transport of mercury to the Arctic. Moreover, it is the first such study to use a fully-coupled, online chemical transport model, Environment Cana...
Observations of OM/OC and specific attenuation coefficients (SAC) in ambient fine PM at a rural site in central Ontario,Canada
Observations OM/OC and specific attenuation coefficients ambient fine PM rural site
2010/3/16
Ambient particulate matter (PM) samples were collected on quartz filters at a rural site in central Ontario during an intensive study in 2007. The concentrations of organic carbon (OC), pyrolysis orga...
