CALPUFF and INPUFF2 also performed well within FB value lower than 0.67. ISCST3 performs the best with the lowest bias in matching field measured odour intensity followed by AUSPLUME. The selected four models fractional biases were all in the acceptable range from -0.67 to 0.67. models such as AUSPLUME are still the most popular regulatory models.

Furthermore, the agreements between the model predictions and measured values could not be improved considerably by using scaling factors. Agreements reached 29 to 35% for all distances and 36 to 48% for distance of 500 to 1000 m. However, if the measurements with intensity zero (no odour) were excluded, the agreements for these models with the conversion equation from University of Manitoba were higher than the results with University of Alberta conversion equations. Considering all the measurements, four models agreement results using the conversion equation from University of Alberta achieved 56% to 62% for all distances and 67 to 76% for distance of 500 to 100m which were better than the obtained using the University of Manitoba conversion equations. The model predicted odour intensities were compared with the measured odour intensities. The AUSPLUME dispersion model is the regulatory model approved for use in NSW by EPA in. In this study, four air dispersion models, ISCST3, AUSPLUME, CALPUFF, and INPUFF2, were evaluated using odour plume measurement data downwind of two swine operations. documents RISC (Version 4, Users Guide, 2001) and Higher Plant. The model evaluation involves comparison of the models predictions with measured field data, which very limited work has been done. It is important that these models be properly evaluated before their predictions can be used with confidence.
