5.10 Following adjustment of the modelled NOx concentrations the total NO2 concentration at the
model verification location has been calculated using the method described in Section 4.18.

The revised NO2 concentration, shown in Table 14, indicates a more acceptable model
performance when compared against the monitored NO2 concentrations. As such, an
adjustment factor of 1.9042 has been applied to all modelled NOx concentrations within
Newington, while an adjustment factor of 5.2 and 2.6 has been applied to all modelled NOx
concentrations along Keycol Hill and within Rainham, respectively.
