『Abstract
This paper reviews the interrelationship among boundary layer,
urbanization, and evolution of ozone, with particular emphasis
on how boundary layer dynamics and urbanization affects the evolution
of ozone under different meteorological and climatological conditions.
The aim of this work is not only to provide an exhaustive investigation
of individual ozone episodes but to look at the underlying issues
and hypotheses that are available for understanding the evolution
of ozone. The review concludes with a summary of the current state
of knowledge and outlines some of the remaining questions. It
is the intention of this paper to serve as an ecumenical reference
to the community for reappraising the relation of boundary layer
climate to the evolution of ozone in an urban setting, especially
on a peculiar feature of ozone dynamic, nocturnal ozone maxima.
To date, there is still no overarching consensus on the mechanisms
that lead to its formation. The importance of levels of urbanization
and advantage of ascertaining the substantial weights of the respective
mixing height and emission structure in exploring the relationship
between ozone evolutions should not be overlooked.
