Ozone Measurements at Several Rural and Urban Sites in New York State

TL;DRAbstract

Since the early 1970s, research to evaluate ozone levels in ambient air has been in progress at several rural and urban site in New York State. The sites were chosen to provide ozone data above and below the nocturnal inversion layer. Ozone from upwind sources has been shown to significantly affect both the urban and remote rural areas. Concentration isopleths show that ozone created in the urban plume of the larger urban areas significantly affects areas downwind under the plume. The sources of ozone in the remote rural areas are still not clear. Principal ozone sources are stratospheric ozone, photochemical production from terpenes and hydrocarbons emitted from local vegetation, and ozone transported via urban plumes. Each of these three sources can be a significant contributor.
