EPA Grant Number: R833746Title: SOA Volatility Evolution: Formation and Oxidation over the Lifecycle of PM2.5
Investigators: Donahue, Neil , Kroll, Jesse H. , Pandis, Spyros N. , Worsnop, Douglas R.
Institution: Carnegie Mellon University , Aerodyne Research Inc.
EPA Project Officer: Chung, Serena
Project Period: September 1, 2007 through August 31, 2011
Project Period Covered by this Report: September 1, 2009 through August 31,2010
Project Amount: $599,990
RFA: Sources and Atmospheric Formation of Organic Particulate Matter (2007) RFA Text | Recipients Lists
Research Category: Air Quality and Air Toxics , Particulate Matter , Air
Objective:
The objective of this project was to identify the major mechanisms for the aging of organic particulate matter in the atmosphere and to implement accurate parameterizations of those findings in air quality models. In so doing, we strove to understand the relative contribution of human activity and natural emissions to organic aerosol levels and to enable and inform policy actions aimed at organic-aerosol reductions.
Progress Summary:
Final year research consisted of completing modeling studies using the 2D Volatility Basis Set, continuing development of the 2D-VBS, and working with co-investigators Kroll and Worsnop on a carbon number-oxidation state general chemistry framework for publication in Nature Chemistry. A substantial amount of paper writing and speaking to discuss the findings filled the rest of the project time.
