摘要：	The University of Denver has completed the first three years of a five-year remote sensing study in the Chicago area. The remote sensor used in this study is capable of measuring the ratios of carbon monoxide, hydrocarbons, and nitrogen oxides to carbon dioxide in motor vehicle exhaust. From these ratios, we calculate the percent concentrations of carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides 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. 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. The third year of this study involved four days of field work conducted at the on-ramp from Algonquin Rd. to eastbound I-290 in northwest Chicago.
