Keywords:   Spray drift, orchard sprayer, LIDAR, micrometeorology, atmospheric stability

Spray aerosols drifting above an orange orchard were scanned with the University of Connecticut elastic backscatter mini-LIDAR in a series of repeated experiments. Three-dimensional plume visualization software was used to analyze the drifting material. Simultaneous measurements of meteorology parameters and atmospheric stability showed that 20% more material was suspended over the canopy during unstable, daytime conditions than stable, evening conditions.
