Short summary
Based on ultra-high-resolution mass spectrometry analysis, we found that β-pinene oxidation-derived highly oxygenated organic molecules (HOMs) exhibit higher yield at high ozone concentration, while limonene oxidation-derived HOMs exhibit higher yield at moderate ozone concentration. The distinct molecular response of HOMs and low-volatile species in different biogenic secondary organic aerosols to ozone concentrations provides a new clue for more accurate air quality prediction and management.
