Paper Abstract

Results from scanning lidar measurements obtained during a large field study entitled Physical and Chemical Evolution of Aerosols in Smelter and Power Plant Plumes will be presented. The Meteorological Service of Canada has recently developed a mobile scanning lidar facility capable of fast azimuth and elevation scanning profiles of the lower troposphere. The lidar was located downwind of the stack source and the scanning speeds were adjusted to allow a complete scanning profile to be collected within 30-60 seconds. The lidar portion of the study was divided into four three- week parts. Ontario Power Generation-Nanticoke is a coal- fired generating station on the shores of Lake Erie. The lidar ground location selected for both the summer and winter study was approximately 8.5 km east of the stacks. The other location was the Noranda-Horne Smelter in Northern Quebec. The lidar was located approximately 4.6 km SE of the smelter during the winter and approximately 2.5 km NNE during the summer study. Preliminary lidar results will be shown for both Nanticoke and Noranda with a focus on the differences between winter and summer periods when the humidity and boundary layer dynamics were very different. New algorithms are being developed to extract boundary layer heights and plume heights for comparison with model predictions.
