Themed Collection dedicated to the 2025 International Conference on Nucleation and Atmospheric Aerosols

Research in nucleation and atmospheric aerosols continues to advance our understanding of the processes that govern atmospheric particle formation, growth and evolution. The field encompasses a broad range of approaches, from nucleation theory and experiments to tropospheric and stratospheric aerosols, cloud drop and ice nucleation and aerosol-climate interactions. This special collection, guest edited by Katrianne Lehtipalo, Zoran Ristovski, Neil Donahue and Paul Winkler, brings together research presented at the 22nd International Conference on Nucleation and Atmospheric Aerosols (ICNAA 2025), highlighting the diverse and cutting-edge work being carried out across the field.
