Climate change is one of the most important global environmental problems affecting natural ecosystems, food production, availability of fresh water as well as human health (1). In acoustic levitation, a sound wave is generated between a piezoelectric transducer and a solid flat or concave reflector; therefore, by altering the distance between transducer and reflector a standing wave can be created and small samples of solids or liquids can be levitated (2). This study has been conducted to improve our understanding of the reactions of O3 and NO3 with a range of terpenes found in the Earth’s atmosphere and the formation and properties of associated organic aerosols.
