Airborne Lidar Tracking of Fluorescent Tracers for Atmospheric Transport and Diffusion Studies

摘要

Development and validation of transport models for the study of regional acid deposition require improved observations of pollutant transport and dispersion processes. Current methods for tracking air-parcel is limited to constant density surfaces using tetroons or by gaseous tracers requiring the use of in situ aircraft. The feasibility of using an airborne lidar system to observe atmospheric transport and dispersion of fluorescent dye particle (FDP) tracers is promising and was demonstrated for various meteorological conditions and FDP release scenarios in the general area of the Cross-Appalachian Tracer Experiment (CAPTEX) during October 1983. The paper presents some of the results obtained on six case studies, each of which illustrates a unique application of the technique. (Copyright (c) 1985 American Meteorological Society.)
