During the months of July and August, 1975, a comprehensive air pollution field monitoring program was conducted in southern New England. Participants in the program included research groups from Washington State University, Battelle Columbus Laboratories, EPA-Research Triangle Park, EPA-Las Vegas and EPA-Region I. Oxidants, hydrocarbons, oxides of nitrogen and other gaseous pollutant species were measured at several ground stations in Connecticut and Massachusetts. The use of three instrumented aircraft provided information concerning vertical dispersion and transport of pollutants. This report provides a tabulation of data collected by Washington State University. It includes surface data from a field laboratory near Groton, Connecticut, plus vertical pollutant information obtained during daily aircraft sampling missions.
