Satellite remote sensing offers a way to complement
these studies by adding the large geographical and seasonal context (Kondratyev
and Varotsos 2002). There is growing interest in examining the contribution of
emission sources of ozone precursors to ambient pollution levels in remote places
due to large-scale transport. The location of the emission regions with respect to
the dominant atmospheric transport patterns has a strong influence on the fre-
quency and strength of intercontinental pollution transport events. In this context,
the plausible role of the aerosols in the ozone dynamics is of crucial importance
(Kondratyev and Varotsos 1995b). For instance, in the marine boundary layer the
interplay between aerosols and air-pollutants becomes significant and must be
taken into account, especially in modelling the ozone budget. In particular, the
uptake (i.e. via diffusion) of the gaseous pollutants on the solid aerosols can be
influenced by the point defects existing in the crystals of the solid aerosols
(Varotsos and Alexopoulos 1980, 1981) keeping also in mind that their thermo-
dynamic properties vary with the air temperature and pressure (Varotsos et al.
1982).
