OSTI ID:355027
Southeastern Aerosol Visibility Study (SEAVS), was a multi-agency, multi-investigator study with one of its objectives to test for consistency among chemical, gravimetric and optical measurements as a way to characterize the composition of the aerosol with a specifiable reliability. SEAVS field measurements took place in Great Smoky Mountains National Park from July 15 to August 25, to characterize the atmospheric aerosol and its contribution to light extinction. Here the authors summarize the results from the various filter-based measurements. They find that sulfate is the most abundant component of the fine particles. Organics are the second largest contributor to the total fine particle mass. Between 28 and 42% of the gravimetrically measured mass could not be identified by the chemical mass measurements. The authors then explore the causes of this lack of closure in gravimetric vs. chemical measurements using the SEAVS data as well as data from other, similar studies reported in the literature.
