The goal of this session is to investigate the connection between the composition and the distribution of boreal biomass burning outflow, ozone production and loss within the outflow, and the resulting perturbation to oxidant chemistry in the troposphere. For this session, we invite oral and poster presentations that include

* observed chemistry within plumes, with particular attention to the NOy and organic chemistry;

* model studies that describe observed chemistry within plumes; and

* quantifying the impact of boreal biomass burning on tropospheric composition using data from ground-based, airborne and spaceborne sensors.
