Abstract

In the past decade interest has focused on the remote analysis of emissions from motor vehicle using spectrometric techniques driven by recognition of the fact that a very proportion of the environmental damage done in this way originates with a small percentage of vehicles. In this paper a remote sensing system designed to measure air-pollutant emission from on-road motor vehicles is described. The system uses a tunable infrared laser differential absorption spectrometer and a technique of UV DOAS. It has been shown to be able to measure CO, C0₂ NO, HC and the dust emissions from on-road individual vehicles. Excellent detection sensitivity is obtained with measure precision.
