| 摘要： | The University of Denver conducted a five-day remote sensing study in the LaBrea, California area in October of 2001. The remote sensor used in this study is capable of measuring the ratios of CO, HC, and NO to CO2 in motor vehicle exhaust. From these ratios, we calculate mass emissions per kg (or gallon) of fuel and the percent concentrations of CO, CO2, HC and NO in motor vehicle exhaust which would be observed by a tailpipe probe, corrected for water and any excess oxygen not involved in combustion. The system used in this study was also 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. Five days of fieldwork, October 15-19, 2001, were conducted as vehicles entered I-10 eastbound frontage road from LaBrea Blvd. in west Lost Angles basin. A database was compiled containing 26,975 records. Of these records the State of California provided make and model year information on 20,319 which contained valid measurements for at least CO and CO2, and most contained valid measurements for HC and NO as well. |
