The Formation and Structure of Tropical Organic/Water Aerosols
EMSL Project ID
19821
Abstract
Atmospheric aerosols are widely recognized as key elements in many environmental issues ranging from global climate change and visibility to adverse effects on peoples health. Aerosols affect climate and rain formation via interactions with incoming solar radiation and through modifications of cloud properties. The production and use of energy often leads, either through direct emission or through subsequent reactions of gas-phase emissions, to the generation of aerosol particles. To address the DOE concerns about the safe production and use of energy it is necessary to improve our understanding of the origin, fate, chemical and physical properties of fine atmospheric particles. In particular, chemical composition and physical properties of secondary organic aerosols (SOA) and their impact on climate on regional and global scales present an area of largest uncertainty in atmospheric sciences. In this work we will study uptake of terpenes and their oxidation products by water microdroplets. Chemical composition of the processed aqueous aerosols will be performed using different mass spectrometry capabilities of EMSL.
