Ground level concentrations of carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), and nitrous oxide (N2O) were investigated in Peterborough, Ontario using Fourier transform infrared spectroscopy. Ground level concentrations of ozone (O3) and nitrogen oxides (NOx) have also been investigated. The seasonal variation and the influence of wind direction on the ground level concentrations of these pollutants has been examined and provided insight to the factors affecting pollutant concentration and sources of air pollution in central Ontario. The source of O3 pollution has also been investigated and indicated that O3 pollution in Peterborough was mainly a result of photochemical activity and that Peterborough was influenced by long-range transport of pollutants from source regions upwind. This result was confirmed by the investigation of the diurnal cycles of O3 and NOx. Finally, the relationship between lower tropospheric O3 and surface O3 concentrations was examined. The results suggested that lower troposphere O3 concentrations were significantly greater than surface O3 levels during the morning, but lower tropospheric O3 did not influence surface morning O 3 concentrations.
