Short summary

Simultaneous observations of PAA, PAN and H₂O₂ are used to provide insight into processes influencing the HO_x chemistry of the boreal forest, including two biomass-burning-impacted periods. A significant contribution from photolytic HO_x sources was included in a box model analysis to align model predictions with measurements. The model predicts high levels of organic peroxy radicals, also at night-time.
