Abstract |
The addendum uses a variety of graphical formats to display and compare the performance of four rural models using the Clifty Creek data base. The four models included MPTER (EPA), PPSP (Martin Marietta Corp.), MPSDM (ERT) and TEM-8A (Texas Air Control Board), Graphic displays were developed and used for both operational evaluation and diagnostic evaluation purposes. Plots of bias of the average vs station downwind distance by stability and wind speed class revealed clear patterns of accentuated underprediction and overprediction for stations closer to the source. PPSP showed a tendancy for decreasing overprediction with increasing station distance for all meteorological subsets while the other three models showed varying patterns depending on the meteorological class. Diurnal plots of the bias of the average vs hour of the day revealed a pattern of underestimation during the nocturnal hours and overestimation during hours of strong solar radiation with MPSDM and MPTER showing the least overall bias throughout the day. |
