Short summary

Monoterpenes emitted by trees are among the volatile organic compounds with the highest global emission rates. The atmospheric degradation of the monoterpene β-pinene was investigated in the atmosphere simulation chamber SAPHIR in Jülich under low NO_x and atmospheric β-pinene concentrations. While the budget of OH was balanced, both OH and HO₂ concentrations were underestimated in the simulation results. These observations suggest the existence of unaccounted sources of HO₂.
