From Molecules to Impacts: Linking the Molecular Composition of Atmospheric Aerosol to Key Physicochemical Properties
From Molecules to Impacts: Linking the Molecular Composition of Atmospheric Aerosol to Key Physicochemical Properties
Session ID#: 279547
Session Description:
Atmospheric particulate matter is a complex and dynamic mixture of organic and inorganic compounds whose impacts on climate, air quality, and human health depend strongly on physicochemical properties including volatility, viscosity, hygroscopicity, light absorption and scattering, etc. While recent advances in analytical characterizations like high-resolution mass spectrometry and spectroscopy have greatly expanded our understanding of aerosol composition, significant gaps remain in directly connecting this molecular information to aerosol properties. This symposium aims to bridge that gap by bringing together researchers working at the interface of analytical chemistry, laboratory studies, field observations, and modeling. We invite contributions that explore how specific molecular features govern bulk and interfacial properties of atmospheric particles. By integrating insights across scales, this session will highlight pathways toward predictive understanding of particulate matter behavior in the atmosphere.
