Trends of ozone and meteorological parameters at high alpine sites
Permanent/Monitoring Project Climate change and changes in the large scale chemical composition of the atmosphere influence thebiodiversity in and the appearance of protected areas even at remote sites. Data sets from Global Atmosphere Watch (GAW) stations are most appropriate to study background air pollution and meteorological trends. For the alpine sites Sonnblick, Jungfraujoch and Hohenpeißenberg we found increasing ozone concentrations until&8776; 2003 especially in winter, whereas in summer there is a small decrease (period 1993-2011). The ozone increase in winter is favoured by changes in the air flow regimes and to some degree in an increasing sunshine duration, whereas in summer thereare notrendsin those meteorological parameters that are relevant for ozone.
