Short summary

This study investigates the radical chemical budget during the limonene oxidation at different atmospheric-relevant NO concentrations in chamber experiments under atmospheric conditions. It is found that the model–measurement discrepancies of HO₂ and RO₂ are very large at low NO concentrations that are typical for forested environments. Possible additional processes impacting HO₂ and RO₂ concentrations are discussed.
