WIDE-AREA REMOTE SENSING OF AIR QUALITY IMPACTS OF ITS
An operational test of a wide-area remote sensing system was conducted to evaluate its ability to monitor air quality impacts of traffic events. A light detection and ranging (LIDAR or lidar) system was used to obtain spatially and temporally resolved images of particulate plumes. Lidar operates on the same principle as does radar, only with a laser beam swept through the atmosphere rather than a radio wave. In this test, the lidar was operated in an urban area and the sweep was confined to distances fairly close to ground level to monitor vehicle-related plumes. The range was about 10 km. Point-sampled measurements of particulate matter and CO concentrations were also made such that comparisons between lidar data and local pollutant concentrations could be made. The objective was to demonstrate the capabilities and limitations of lidar technology for use as an air quality monitoring tool.
