4.3.3      Predicted Mixing Heights
Figure 4.4 presents a plot showing predicted mixing heights for each hour of the day. As expected,
higher mixing heights occur during the day time, while lower mixing heights occur during the night
period when stable conditions are dominant and temperature inversions occur.




° Represents outliers to the data set. Outliers are defined as those values in the data set which are
greater than 1.5 x the Inter Quartile Range above the upper (Q3) or lower (Q1) quartiles.
