Impact/Purpose:
The purpose of this poster is to highlight STAR contributions to the recent Southern Oxidant and Aerosol Study (SOAS) field campaign.
Description:
The Southern Oxidant and Aerosol Study (SOAS) is a community-led field campaign that was part of the Southeast Atmosphere Study (SAS). As one of the largest field studies in decades to characterize air quality in the Southeastern United States, SAS is a collaborative project involving the US Environmental Protection Agency (EPA), the National Science Foundation (NSF), the National Oceanic and Atmospheric Administration (NOAA), the Electric Power Research Institute (EPRI) and dozens of domestic and international research institutions.In 2013, the EPA’s Science to Achieve Results (STAR) grants program funded fourteen projects, resulting in a research portfolio addressing a number of scientific needs outlined in the solicitation. These projects fall into two categories: field measurements of key chemical species and supporting laboratory experiments and model development. Awardees participating in the SOAS campaign are studying key chemical species (including volatile organic compounds, formaldehyde, reactive nitrogen species, reactive oxidant species, organonitrates and organosulfates) for understanding the interactions between anthropogenic and biogenic emissions. Measurements were made by instruments both on the ground and from aircrafts. Additionally, projects characterized and investigated the climatically-relevant properties of aerosol from the field site. Work also includes several chamber experiments that will result in a detailed analysis of secondary organic aerosol components and precursors. Certain species measured in the field campaign will be analyzed and characterized in a laboratory setting. Finally, three projects focus on improving air quality and climate models, particularly in areas dealing with cloud droplets, aqueous chemistry, and organic aerosol mixtures. This poster will provide an overview of the STAR grants program’s contribution to the SAS and SOAS campaign and highlight some of the challenges and benefits of leveraging funds in this way.
