Environmental Photochemical Catalysis and Microphysical Properties of Fe-Organic Aerosols


EMSL Project ID
51372

Abstract

The intent of this collaborative research is to investigate photo-catalytic effects of atmospheric aging on the chemical composition and the microphysical properties of secondary organic aerosol (SOA) internally mixed with Fe(III)-rich mineral dust. Using novel approaches for molecular-level characterization and chemical imaging hosted by EMSL, we will conduct in-depth studies of chemical and physical properties of atmospheric particles with the objective to understand a fundamental relationship between chemistry of the selected aerosol system and its atmospheric impact.
