Boreal fire emissions have little effect on ozone concentrations but evident impact on some NOx
reservoirs as peroxy nitrates that we quantified. This should be taken into account since NOx
reservoirs can be efficiently transported and may influence the ozone budget far away from the fire emission.
The study is based on observations carried out on board the BAe 146 aircraft during BORTAS in Canada. We used a custom laser-induced fluorescence system to measure NO2
