Measurements of ozone, NO, NO2, NOy, CO, VOC, and SO2 collected with the Baylor University Twin Otter aircraft during TexAQS 2000 were analyzed to better understand the source types that contributed NOx (NO+NO2) and VOC precursors to the ozone production observed. Source types were identified through analysis of SO2/NOy and CO/NOy ratios observed. Also presented is an analysis of the effect of measurement uncertainties on the results.
