Short summary
Native to Australasia, the remarkable adaptability, rapid growth rates and high quality wood of eucalypt trees has led to them the most widely planted hardwood forest trees in the world. In contrast to boreal and tropical forests, there has been little study of aerosol formation in these regions. Here, we study the secondary organic aerosol formation from the very fast reaction of α-phellandrene, emitted from eucalypts, and identify key products and reaction pathways.
