Abstract

 This research will focus on direct photochemical processing of organic aerosol particles by solar radiation. It will address the following important questions: (1) How do direct photochemical processes change chemical composition of SOA and POA particles? (2) How is the ability of organic particles to act as cloud condensation nuclei (CCN) affected by solar radiation? To answer these questions, we will investigate photochemical processing of several highly-representative types of laboratory generated aerosol particles using unique capabilities provided by the EMSL user facility.We will utilize a newly established EMSL capability - a high resolution Thermo LTQ Orbitrap™ hybrid mass spectrometer located in Dr. Alex Laskins laboratory, which enables fast, sensitive and reliable detection and identification of compounds in complex mixtures.
