Molecular Characterization of Organic Aerosols from the Los Angeles
Ground Site (CalNex 2010) Using High-Resolution Mass Spectrometry
EMSL Project ID
39490
Abstract
The objective of the proposed project is to perform detailed, molecular level characterization of the chemical composition of organic aerosol (OA) samples collected during the CalNex 2010 study (May 10 - June 16, 2010) and provide critical data for closure studies focused on (a) fundamental understanding of molecular mechanisms of secondary organic aerosol (SOA) formation, its chemical transformations and atmospheric aging of OA, (b) detection and chemical characterization of light absorbing molecules pertinent to 'brown' organic carbon, (c) molecular composition of water soluble organic compounds (WSOC) in aerosols and their effects on hygroscopic properties of aerosols. The experiments will require unique ESML aerosol collection and analysis capabilities.
