Short summary
The particle chemical morphology is important to atmospheric multiphase and heterogeneous chemistry. This work directly observed the core-shell structure and water uptake behavior of individual submicron aerosol particles at an urban site and elucidated the potential impact on particle reactive uptake and heterogeneous reactions.
