Evaluation of area source models to predict near ground level concentrations due to emissions released during agricultural applications

► Three area source models: the Shear, the Parker, and the Smith were statistically evaluated. ► Two data sets: methyl isothiocyanate and particle concentrations were used in the evaluation. ► Shear model performed best out of the three models. ► The performance difference was due to vertical variation of wind speed and eddy diffusivity.
