Short summary
We present a case study of an intense wildfire smoke plume from Siberia that affected the air quality across the Pacific Northwest on 6–10 July 2012. The transport, entrainment, and chemical composition of the plume are examined to characterize the event. Ambient O3 and PM2.5 from surface monitoring is contrast to modelled baseline air quality estimates to show the overall contribution of the plume to exceedances in O3 and PM2.5 air quality standards and objectives that occurred.
