The Airborne Xanthomonas Experiments – Madras 2023 (AXE-M2023) dataset contains field-scale measurements of particle dispersion, deposition, and atmospheric turbulence during combine harvesting in Madras, Oregon, conducted over nine replicate trials in September 2023. Fluorescent microspheres of known sizes (33 µm and 165 µm) were released into the atmosphere from a combine harvester, and their downwind transport and deposition were measured using rotorod impaction traps, adhesive-coated deposition plates, and Cascade Settling Traps (CSTs). Simultaneously, two meteorological towers recorded turbulence and micrometeorological conditions using sonic anemometers and particle counters. The dataset includes spatial coordinate grids, deposition counts, derived mass concentrations, meteorological variables, and spliced images of deposition plates, all formatted in structured .CSV, .MAT, and .ZIP files. These data support analysis and modeling of near-surface transport dynamics, turbulent dispersion, and bioaerosol deposition in agricultural environments.
This dataset encompasses the results of a series of controlled experiments conducted at the University of Utah's Industrial Hygiene Research Laboratory between November 2021 and November 2022. It includes data from tests assessing aerosol containment and surface contamination using the U-COVER device. The dataset details the effectiveness of different device designs (D1A, D1B, D2) in containing salt aerosols under various conditions, including with and without exhaust ventilation. Measurements were conducted using GRIMM Model 1.109 Portable Aerosol Spectrometers and analyzed for particle size distributions and concentrations. The findings provide insights into the protective capabilities of the U-COVER device in medical settings, with implications for healthcare worker safety."
