Atmospheric aerosols (particulate matter) play an important role in terms of health issues as well as climate. Especially during the cold season reports on aerosols and related health issues have become an important topic. Air quality standards set for particulate matter in ambient air (PM10; particulate matter smaller than 10 µm a.d.) are exceeded in many regions in Europe. It has been shown (Puxbaum et al. 2004) that at least in a number of cases these limit violations are already driven by elevated background concentration levels, which leave little tolerance for emissions in source regions, e.g. densely populated cities. Conditions at the Sonnblick Observatory (SBO) are definitely not the ones which can be attributed to possible violations of limit values of PM10. On the contrary, the sampling site in the remote mountainous region of the Alps offers the opportunity for the determination of background concentrations. These results can also be used for assessing the influence of background concentrations of aerosol particles on climate issues.
Here we summarize the experimental setup and selected results of a two year sampling campaign of atmospheric aerosols at the Sonnblick Observatory.
