Transport of Canadian Wildfire Smoke to the Mid-Atlantic U.S

High spatial and temporal resolution Elastic light detection and ranging (lidar) measurements allows to monitor long-range transport of particulates, such as dust and smoke, that impact local and regional air quality. These lidar measurements enhance current knowledge and understanding on how vertical layering and long range transport of natural and anthropogenic particle pollution may alter the relationship between column aerosol optical depth and surface particle pollution concentrations. The impact of a strong haze event in June 9-11, 2015 is examined. Particle pollution associated to this event yielded a 245% increase in aerosol optical depth values compared to the average mean June values for the last decade. We present how air mass back trajectory analysis, aerosol intensive and extensive parameters from lidar, sun-photometer and satellite observations revealed the presence of Canadian wildfire smoke impacting the Baltimore air quality.
