Short summary
Here we present a study of the photooxidation of alpha-pinene, the most abundant monoterpene, by hydroxyl radicals (OH) conducted in the simulation chamber SAPHIR under low NOx and atmospheric alpha-pinene concentrations. Yields of the main degradation products acetone, formaldehyde, and pinonaldehyde were determined and the HOx (OH + HO2) radical budget was investigated. Measurements were used to test current atmospheric models and a theory-based mechanism.
