摘要：	The University of Denver conducted a five-day remote sensing study in the Tulsa, Oklahoma area in September of 2017. The remote sensor used in this study measures the ratios of CO, HC, NO, SO2, NH3 and NO2 to CO2 in motor vehicle exhaust. From these ratios, we calculate the percent concentrations of CO, CO2, HC, NO, SO2, NH3 and NO2 in the exhaust that would be observed by a tailpipe probe, corrected for water and any excess oxygen not involved in combustion. Mass emissions per mass or volume of fuel can also be determined and are generally the preferred units for analysis. The system used in this study was configured to determine the speed and acceleration of the vehicle and was accompanied by a video system to record the license plate of the vehicle and, from this record, the vehicle’s model year. Since fuel sulfur has been nearly eliminated in US fuels SO2 emissions have followed suit and while we collected vehicle SO2 measurements we did not calibrate those readings and they are not included in the discussion of the results. Five days of fieldwork, September 11 – 15, 2017, were conducted on the uphill interchange ramp from westbound US64 (Broken Arrow Expressway) to southbound US169. This is the same location previously used for measurements in the fall of 2003, 2005, 2013 and 2015. A database was compiled containing 22,583 records for which the State of Oklahoma and the Cherokee Nation provided registration information. All of these records contained valid measurements for at least CO and CO2, and most records contained valid measurements for the other species as well.
