Short summary
By utilizing a new analysis approach, we investigated atmospheric oxidation of biogenic volatile emissions in a Finnish forest, measured by chemical ionization mass spectrometry. We identified several new compound groups, including low-volatility accretion products and their formation pathways. Results from this study are important for understanding atmospheric aerosol formation, as well as providing new perspectives on future lab studies and data analysis of short-lived species.
