The Regional Nature of Ozone and Fine Particulate Matter
Russell R Dickerson, The University of Maryland, College Park, MD; and A. Chen, B. G. Doddridge, R. D. Hudson, and B. Holben
Ozone and its precursors and the chemical composition and optical properties of aerosols were measured at several surface sites including Ft. Meade, MD and Philadelphia, PA during the NEOPS campaigns. We compare these to data sensed remotely with sun photometers and satellites. Results show spatial and temporal coherence in ozone and aerosol particles. This regional nature results from a combination of emission patterns, meteorological conditions and a physical link between photochemically produced oxidants and secondary particle formation.
