Short summary
Tiny air particles (aerosols) influence clouds, sunlight, and air chemistry. Our study examined how these particles form in a plant-rich region of Southeast Australia. We found frequent new particle formation (NPF) events, often linked to pollution plumes. Volatile organic compounds (VOCs) from plants and other factors influence NPF and aerosol growth. Nighttime NPF requires further study. Overall, plant emissions play a key role in aerosol formation in this region.
