Evaluation of the AgDISP aerial spray algorithms in the AgDRIFT model

摘要

A systematic evaluation of the AgDISP algorithms, which simulate off-site drift and deposition of aerially applied pesticides, contained in the AgDRIFT~R model was performed by comparing model simulations to field-trial data collected by the Spray Drift Task Force. Field-trial data used for model evaluation included 161 separate trials of typical agriculture aerial applications Under a wide range of application and meteorological conditions. Input for model simulations included information on the aircraft And spray equipment, spray material, meteorology, and site geometry. The model input datasets were generated independently of The field deposition results, i.e., model inputs were in no way altered or selected to improve the fit of model output to field results.
