The surface maps for O3 (Figures 6e–6f) show similar patterns
for 2012 and 2020 scenario, which mean that the exceedances of
the target value modeled for 2012 year continue to occurred in
2020. For this case, additional measures would be needed to
mitigate this pollutant concentration. A more detailed study
regarding both precursor pollutants – NOX and VOC – is required in
order to study the type of measures/strategies that would be more
efficient to reduce O3 values taking into account the interaction
and chemistry processes involved (Seinfeld and Pandis, 2006).
