| Zusammenfassung |
| The goal of this work is to investigate the connection between PNS and ozone within plumes
emitted from boreal forest fires and the possible perturbation to oxidant chemistry in the
troposphere. During the Aircraft campaign in Canada called BORTAS (summer 2011 ) were
carried out several profiles from ground up to 10 km with the BAe-146 aircraft to observe the
atmospheric composition inside and outside fire plumes. The BORTAS flights have been
selected based on the preliminary studies of “Plume identification”, selecting those effected
by Boreal forest fire emissions (CO > 200 ppbv). The FLAMBE fire counts were used
concertedly with back trajectory calculations generated by the HYbrid Single-Particle
Lagrangian Integrated Trajectory (HYSPLIT) model to locate the sources of Boreal biomass
burning.Profiles measured on board the BAe-146 aircraft are used to calculate the
productions of PNs and O3 within the biomass burning plume. By selecting the
flights that intercept the biomass burning plume, we evaluate the ratio between the
ozone production and the PNs production within the plume. Analyzing this ratio it is
possible to determine whether O3 production or PNs production is the dominant
process in the biomass burning boreal plume detected during BORTAS campaign. |
