LIDAR images of a plume over a forest canopy are analyzed to estimate instantaneous vertical dispersion, and vertical meander of the plume centerline. Turbulence parameters calculated from the LIDAR images are compared with parameters derived from sonic anemometer data collected near the plume release point. It is argued that analysis of lidar images of spray plumes is an accurate and efficient way to estimate turbulence parameters for spray transport models in cases when installation of fast-response, in-situ, measurements are not practical.
