As the regional models required to understand and control the
generation, distribution and deposition of air pollutants become more
precise, the need to understand the detailed effects of hilly and
mountainous terrain becomes more acute. The Alpine regions and the
mountainous Mediterranean coasts have large effets on the way the
pollutant burden is spread in their areas. Similarly an understanding of
the effects of chemical and physical processes controlling pollutant
deposition and the emission of biogenic compounds is essential to the
correct modelling of the coastal regions which surround so much of
Europe.
The results from two projects on these problems are presented in this
volume: one involved a series of field campaigns in the Alps and in the
Rhine valley, the other involves ships and platforms in the North Sea
and also in the Mediterranean.
