Description:
A regional scale aircraft sampling program was conducted during August 1979 to obtain data for validation of a regional scale photochemical air quality simulation model and for studying the physical and chemical processes important in long-range transport of ozone and ozone precursors throughout the diurnal cycle. Three aircraft were used to obtain continuous measurements of O3, NO, NOx, B-scat, and grab samples for later analysis for hydrocarbon species. The field program is described and Lagrangian sampling data for a 24-hour period presented and discussed with the conclusion that relatively high ozone concentrations, generated within urban plumes, were transported from Ohio to the Northeast Corridor.
