Final data and analysis report on high-resolution in plume concentration fluctuations measurements using lidar remote sensing technique

摘要

The multi-nation, high-resolution field study of Meteorology and Diffusion over Non-uniform Areas (MADONA) was designed and conducted for high resolution meteorological data collection and diffusion experiments using smoke, sulphur hexafluoride (SF6), and propylene gas during unstable, neutral, and stable atmospheric conditions in an effort to obtain terrain-influenced meteorological fields, dispersion, and concentration fluctuation measurements using specialized sensors and tracer generators. Thirty-one days of meteorological data were collected during the period 7 September through 7 October and 27 diffusion experiments were conducted from 14 to 23 September 1992. Puffs and plumes of smoke and SF6 were released simultaneously for most of the experiments to gauge the resultant diffusion and concentration behavior. Simulations of airflow and diffusion over the MADONA topography were made with a variety of models. Wind fields and wind-related parameters were simulated with several high resolution wind flow models. (au) 2 tabs., 17 ills., 7 refs.
