Elastic backscatter lidar measurements of aerosol plumes have been used in to quantify the effects of nocturnal planetary boundary layer structure, dynamics, turbulence, and wave structures on plume dispersion. In conjunction with lidar measurements of a continuous source aerosol plume, simultaneous micrometeorological measurements were made. Techniques for determining plume dispersion parameters, plume concentration and plume meander have been developed to help merge the lidar and micrometeorological measurements. This will allow for a more complete understanding of turbulence and wave structures. The details of these new lidar techniques as well as initial results of the joint study will be presented.
