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 NOx 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.
