Summary: | •Particle dispersion near the source in a trellised agricultural canopy is studied.•Concentration data was obtained during field experiments using a 3D sampling array.•Plume behavior was investigated using a novel Gaussian-based interpolant.•The canopy architecture had a significant impact on plume shape.•Shape parameters varied with mean wind direction relative to the canopy.
Agricultural systems are exposed to and influenced by particles of many types (e.g., pathogens, pollen, pests), the concentrations of which are typically highest in the regions immediately surrounding their sources. The intermittent nature of trellised canopies creates an unique canopy architecture that directly affects the shape of particulate plumes and tends to alter their transport patterns in the near-source region. To investigate the behavior of particle plumes near their sources in a trellised canopy, a set of particle release experiments was conducted during a field campaign in an Oregon vineyard in 2013. Specifically, plumes of inert fluorescent microspheres (10–45 μm diameter) were released into the canopy during periods when the mean wind direction was significantly different from the vine-row direction. Plume concentrations were collected at over 100 separate locations in a three-dimensional space |
