Short summary

Primary emissions and aging of open straw burning plumes were characterized in ambient dilution conditions in a chamber. Rich in alkenes, the plumes have high O₃ formation potential. The emissions of specific particulate and gaseous compounds were less when the straws were fully burned. Organic aerosol (OA) mass increased by a factor of 2–8 with 3–9 h photo-oxidation, yet > 70 % of the mass cannot be explained by the known precursors. OA gained more O- and N-containing compounds during aging.
