| 摘要： | The University of Denver conducted five days of remote sensing in the Denver, Colorado area in December of 2017 and January of 2018. 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, one can 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 equipment used in this study was configured to determine vehicle speed and acceleration, and included a video system to record license plate information. The latter was subsequently used to obtain non-personal vehicle registration information. Since fuel sulfur has been nearly eliminated in US fuels SO2 emissions have followed suit and while vehicle SO2 measurements are collected they were not calibrated and the measurements are not included in the discussion of the results. |
