Paper from the SOLAS endorsed project AMBIEnCE on dynamic structural model of organic aerosols in a costal marine site
A paper entitled 'Exploring water-soluble organic aerosols structures in urban atmosphere using advanced solid-state 13C NMR spectroscopy', from the SOLAS endorsed project AMBIEnCE published.
This article describes a new quantitative structural model of inhomogeneous atmospheric aerosol water-soluble organic matter (WSOM) in rapidly changing atmospheric conditions at a costal marine site. We confirmed the presence of three independent classes of compounds that vary both in content and molecular diversity within very short periods of time: heteroatomrich aliphatic (either chain or branched), carbohydrate-like moieties, and highly substituted aromatic units. These findings of AMBIEnCE project are crucial to bridge the gap and resolve the discrepancies between modeled and measured aerosol WSOM, enabling a better representation of organic aerosols in climate studies.
