Abstract

Researchers from the University of Minnesota collected size-resolved aerosol samples with two microorifice uniform deposit impactors (MOUDIs) during the Southern California Air Quality Study (SCAQS). Samples were analyzed for elemental and organic carbon. Objectives of these measurements are to associate the role of organic and elemental carbon in phenomena including dry deposition and optical extinction, and to investigate the evolution of secondary organic aerosols by gas to particle formation in the atmosphere. The top-stage-foil data was therefore used to determine organic and elemental blank corrections. Based on the variability in these blanks and on variabilities in duplicate analyses of a subset of the foils the uncertainties for elemental (EC) and organic (OC) carbon measurements are estimated in this study.
