The main objective of the workshop was to increase our knowledge of
ozone formation and distribution in the troposphere, its relation
to precursor (NO and HC species) distribution, how it is affected
by transport processes in the troposphere, and to show how the
increasing levels of ozone can cause environmental problem. The
focus was on the interaction of ozone on regional and global
scales. There is mounting evidence that such interactions occur and
that the ozone levels are increasing in most of the Northern
Hemisphere tropo sphere. A likely source of ozone increase is human
activity. As result of this, tropospheric climate may change
significantly within a few decades, either through direct effects
by ozone itself or indirectly through its effect on other
radiatively active trace species. Further more, ozone may have
adverse effects on vegetation over large continental areas due to
enhanced levels which have been measured to take place. As it is
well known that ozone plays a key role in the oxidation of a large
number of chemical species in the troposphere, natural as well as
man-made, the atmospheric distribution of important trace species
like sulfur dioxide, nitrogen oxides and hydrocarbons could be
markedly changed as a result of ozone changes. The rapidly
increasing interest in tropospheric ozone, and the key role ozone
plays in several atmospheric areas as well the obvious increase in
the tropospheric concentration of ozone made ozone a natural choice
as a topic for the workshop."
Recent studies have demonstrated a link between ozone changes
caused by human activities and changing UV levels at the Earth's
surface, as well as a link to climate through changes in radiative
forcing and links to changes in chemical composition. This book
draws together key scientists who provide state of the art
contributions on the variable ozone layer and the interplay of
longwave and shortwave radiative interactions which link ozone, the
climate and UV issues.
