The deposited particles were weighed and counted. The airborne concentration of coarse particles was measured with a Rotary Impactor. Deposition velocity was determined by dividing the mass flux (plate) by the airborne concentration (Rotary Impactor). The deposition velocity was considered to be due to gravitational settling (<em>V</em><sub><em>ST</em></sub>) and inertial deposition (<em>V</em><sub><em>I</em></sub>). Deposition to the upper plate surface (<em>V</em><sub><em>dU</em></sub>) was given by: <em>V</em><sub><em>dU</em></sub> = <em>V</em><sub><em>ST</em></sub> + <em>V</em><sub><em>I</em></sub>, while deposition to the lower plate surface (<em>V</em><sub><em>dL</em></sub>) was given by: <em>V</em><sub><em>dL</em></sub> = − <em>V</em><sub><em>ST</em></sub> + <em>V</em><sub><em>I</em></sub>.

This simple model is based on solving the mass conservation equations which include chemical reaction terms in the cells of a two-dimensional crosswind plane which moves with the air parcel. Testing of the model is done in three ways. First, the chemistry is evaluated using results of smog chamber experiments simulating Melbourne's emissions and meteorological conditions. Second, the accuracy of the emissions inventory is tested using aircraft measurements. Finally the overall performance of the model is evaluated using monitoring station data. In general the model gives good agreement with the measurements, with the predictions for O<sub>3</sub> being somewhat better than those for NO<sub>2</sub>.

The Oklahoma data base involved two separate experiments with measurements taken at 100 and 600 km arcs downwind of a 3-h perfluorocarbon release. The Savannah River Plant data base encompassed 15 experiments with measurements taken over 2–5 days at distances of 28–144 km downwind from a 62 m stack release of Kr-85 gas.</p><p>Application of the American Meteorological Society statistics to the model/data comparisons showed that six of the eight models predicted within a factor of two of the observed concentrations for all of the following: points paired in space and time, points paired in space only, and for points unpaired in space and time. However, the ratio of the standard deviation of residuals to the average observed value showed improvement as more unpairing was done in the comparison of the models with the data. The statistical comparisons reveal a definite tendency of the models to overpredict plume concentrations. Supplemental graphical comparisons showed that plume concentration overprediction is accompanied with an underprediction of plume spreading, and that a definite time lag is often observed between the time of arrival of the observed plume and the time of arrival of the predicted plume.</p><p>The causes of model/data discrepancies can be largely traced to inadequate wind field modeling that leads to an incorrect temporal and spatial positioning of the plume, and the use of the Turner [Workbook of atmospheric dispersion estimates.

The use of multilayer wind field models and the use of the Heffter [<em>J. appl.
