EATOUGH, D. J., B. GROVER, W. WOOLWINE, R. FARBER, AND W. F. CHRISTENSEN. APPLICATION OF PSCF TO PMF-MODELED SOURCES OF PM2.5 IN RIVERSIDE USING 1-HR AVERAGED DATA. Presented at Air and Waste Management Association Annual Conference, Pittsburgh, PA, June 26 - 29, 2007.
Impact/Purpose:
The objective of this task is to provide data and tools to support implementation of PM NAAQS. Specifically, this task will provide:
(1) Monitoring methods to determine compliance with NAAQS.
(2) Atmospheric chemistry models to enhance air quality models used for development, evaluation, and adjustment of State Implementation Plans (SIP).
(3) Receptor modeling tools and applications to identify sources contributing to air pollution in non-attainment areas to support development, evaluation, and adjustment of SIPs.
Description:
Data from semi-continuous instruments employed during a sampling campaign in Riverside, CA in July-August 2005 was used in a PMF2 analysis and sixteen sources were identified. Factors attributed to being primarily from local automobile emissions, local diesel emissions, wood combustion and local secondary photochemical associated sources were found. Several transport attributed factors were also identified, including, transported nonvolatile material, transported secondary ammonium nitrate, and transported secondary organic material. The PMF2 results were combined with hourly averaged back-trajectory data from HYSPLIT to identify factors associated with specific meteorological transport conditions.
