The purpose of this study was to use lidar technology to identify organized structures in the stable surface layer over a forest. An experiment was conducted at a 20 m tall mixed deciduous canopy in Coventry, Connecticut where smoke releases from a 35 m tower were scanned with a Nd:YAG pulsed laser. The backscattered signal was referenced to detect flow fluctuations. These returns were correlated with simultaneous micrometeorological measurements to quantify the flow.
