Title: Application of IR remote sensing technology for monitoring of intersection CO concentrations in Albuquerque, New Mexico

This paper reports the preliminary testing of an infrared (IR) remote sensor (GASCOFIL) for the detection of carbon monoxide (CO) concentrations near the intersection of San Mateo Drive and Menaul Drive in Albuquerque, New Mexico on May 11, 1993. The goal of this test was to demonstrate the effectiveness of GASCOFIL as an in-situ monitor for studying the time dependent distribution of CO at intersections. In order to measure the concentration of CO, the sensor viewed a crossroad path seven feet above Menaul Drive three hundred and fifty feet from the center of San Mateo Drive. The sensor was positioned ten feet from a gas and aerosol-monitoring station equipped with an EPA approved point CO monitor. GASCOFIL produced real time data that showed variations in CO levels that correlated with traffic light cycles. Variations in the CO concentration due to individual vehicles were also recorded. A two hour average of the GASCOFIL CO concentration data taken through rush hour was six percent lower than CO data taken from an EPA point sensor adjacent to the intersection. The small percentage variance between the two averages might be due to the separation and size difference of the sample volumes. GASCOFIL measured variationsmore » and peaks in the CO concentration not seen by the EPA sensor because it had a faster time response and its sample volume was closer to the vehicular sources.« less
