Wind tunnel measurements of drop size distributions from Micronair AU4000 and AU5000 rotary atomizers werecollected to develop a database for model use. The measurements varied tank mix, flow rate, air speed, and blade angleconditions, which were correlated by multiple regressions (average R2 = 0.995 for AU4000 and 0.988 for AU5000). Thisdatabase replaces an outdated set of rotary atomizer data measured in the 1980s by the USDA Forest Service and fills in agap in data measured in the 1990s by the Spray Drift Task Force. Since current USDA Forest Service spray projects rely onrotary atomizers, the creation of the database (and its multiple regression interpolation) satisfies a need seen for ten years.
