Effects of the 2015 summer wildfires in western Canada on air quality in eastern North America

Smoke from western forest fires in Alberta and Saskatchewan during June and July, 2015 drifted eastward across the Great Lakes region, eastern Canada and northeastern US during July and caused distinct increases in concentrations of fine particles measured at air quality monitoring stations during several days. In this poster, the meteorological factors that caused smoke plumes to move across the continent and to get transported downward to the surface are examined.
