One of the principal concerns in recent years regarding the atmospheric
environment has been the formation of ozone and other photo-oxidants
over much of Europe in the summer. Ozone is formed in the atmosphere by
a complex series of chemical reactions in the presence of sunlight from
volatile organic compounds and nitrogen oxides. As the reactions take
place in air flows determined by the detailed meteorological situation,
the measurement, interpretation, understanding and modelling of the
levels, fluxes and origins of the ozone are extremely difficult. The
present volume reviews several of the currently important questions and
presents detailed reports from investigators all over the continent. As
such, it provides insight into the current scientific views about ozone
in Europe.
