Abstract:This paper presents an overview of the 1999 Atlanta Supersite Project coordinated through the Southern Oxidants Study and the Georgia Institute of Technology (GIT) and funded by the US EPA along with other sponsors who provided in-kind support primarily through existing studies. The Atlanta Supersites Project was located at the existing SEARCH/ARIES site on Jefferson St. in NW Atlanta, GA. The primary objective of the Atlanta Supersites Project was to evaluate and compare advanced measurement methods for particulate matter mass and its components. Methods included filter/denuder based time-integrated or discrete samplers, a variety of semi-continuous methods measuring mass, its major components (sulfate, nitrate, ammonium, organic carbon, elemental carbon, trace elements) and gas phase precursors, and for the first time ever, a comparison among particle mass spectrometers, four in total. These data were complemented by meteorological data as well as gas phase criteria pollutant measurements and other supplemental data, such as particle physical properties, VOC, oxygenated VOC, and NOy. The primary and supplemental data also were used to better understand the formation and accumulation of PM in Atlanta and to better understand source-receptor relationships. This paper overviews the study, summarizing objectives, the site and measurements, the relative reference data used for comparisons, overviews the meteorological and chemical characteristics of pollution in Atlanta during the study, puts the study in context of Atlanta and the Southeast US, and finally summarizes the key findings from the over 30 publications published, submitted, or in preparation. This paper also provides as complete a list as is currently available of those publications. Others certainly will be emerging over time. The comprehensive database is available through the Atlanta Supersites Project web site sponsored by GIT (http://www-wlc.eas.gatech.edu/supersite/).

The United States Environmental Protection Agency through its Office of Research and Development funded and managed or partially funded and collaborated in the research described here under Assistance Agreement No. CR824849 to the Georgia Institute of Technology in Atlanta, GA. It has been subjected to Agency review and approved for publication.
