Short summary

Chamber experiments were conducted with alpha-pinene and chlorine under low- and high-nitrogen-oxide (NO_X) conditions. We estimated the HOM yields from chlorine-initiated oxidation of alpha-pinene under low-NO_X conditions to be around 1.8 %, though with a uncertainty range (0.8 %–4 %) due to lack of suitable calibration methods. Our study clearly demonstrates that the chlorine-atom-initiated oxidation of alpha-pinene can produce low-volatility organic compounds.
