EMERGING SCIENCE: EPA'S ORD SUPPORTS REGIONAL HAZE PROGRAM; POSTERS FROM BOSC REVIEW AND SCIENCE FORUM
DIMMICK, F. EMERGING SCIENCE: EPA'S ORD SUPPORTS REGIONAL HAZE PROGRAM; POSTERS FROM BOSC REVIEW AND SCIENCE FORUM. Presented at Regional Planning Organization, Denver, CO, June 09 - 10, 2005.
1. Using laboratory and field study data generated during FY99-FY04, develop a science version of a PM chemistry model for predicting ambient concentrations of water, inorganics, and organics in PM2.5 samples. The model will include the Aerosol Inorganic Model for predicting concentrations of inorganic compounds and a computational chemistry-based method for predicting concentrations of organic compounds.
2. Identify and evaluate methods for analyzing the polar fraction of PM2.5 samples.
3. Carry out short term field studies in Research Triangle Park, North Carolina in the summer and the winter to determine the composition of the organic fraction of ambient PM2.5 samples, with special emphasis placed on identifying and determining ambient concentrations of polar compounds.
4. Conduct laboratory studies to establish the chemical composition of secondary organic aerosol (SOA) and to determine source signatures for aromatic and biogenic SOA.
5. Conduct laboratory and theoretical investigations of thermodynamic properties of polar organic compounds.
6. Evaluate the science version of the PM chemistry model using laboratory and field data generated under this task as well as other available data in the literature.
7. Conduct PM chemistry-related special studies for OAQPS
A series of presentations from EPA's Board of Science Councilors review in April 2005 and the Science Forum in May 2005 are being made available to the Regional Planning Organization conference on June 9-10, 2005. Attendees will be able to review the materials during the conference, learning about ORD research into atmospheric sciences. An overview presentation is being made to introduce the topic to the conference.
