Objective:
This is one of the projects conducted by the Research Consortium on Ozone and Fine Particle Formation in California and in the Northeast United States. In this particular project, source-oriented air quality model predictions of the size and chemical composition of individual atmospheric particle classes were evaluated against single-particle measurements taken by aerosol time-of-flight mass spectrometry (ATOFMS) and applied to assess the source apportionment accuracy of a single-particle receptor-oriented method. The distinguishing feature of the air quality model used in these studies is that the ambient aerosol is represented as an ensemble of compositionally distinct particle classes, rather than as an internally mixed distribution in which the chemical composition of all like-sized particles are assumed to be identical. The air quality model tracks the physical diameter, chemical composition, and atmospheric concentration of thousands of particle classes as they are transported from sources to receptors while undergoing atmospheric chemical reactions. Each particle class interacts with a common gas phase, but otherwise evolves separately from all other particle classes, yielding an aerosol population in which particles of a given size may exhibit different chemical compositions (Kleeman, et al., 1997).
