Stony Brook Univ., Stony Brook, NY (United States).We discuss applications of these novel approaches in recent studies and highlight additional research areas to explore the environmental effects of air-surface interactions. When combined, these approaches provide a comprehensive arsenal of tools for understanding the nature of particles at air-surface interactions and their reactivity and transformations with atmospheric aging.
We highlight a range of modern analytical approaches that enable multimodal chemical characterization of particles with both molecular and lateral specificity. Once emitted, particles undergo transformation via atmospheric aging processes that further modify their complex composition. The diversity between chemical constituents and lateral heterogeneity within individual particles adds to the chemical complexity of particles and their surfaces. The overarching goal of these studies is to advance predictive understanding of atmospheric particle composition, particle chemistry during aging, and their environmental impacts. This article presents an overview of recent advances in field and laboratory studies of atmospheric particles formed in processes of environmental air-surface interactions.
