  • Vertical distribution and diurnal variation of ozone in an Alpine valley in national park "Hohe Tauern", Austria
    Gomišček, Boštjan ; Puxbaum, Hans
    Ozone is one of the most important atmospheric trace gases because it interacts in various ways with many components of the atmospheric system and plays a crucial role in the tropospheric chemistry: ... Crutzen (1988), Penkett (1988), Volz and Kley (1988). This knowledge and awareness that elevated ozone concentrations can cause demages on vegetation and also affect human health, stimulate a lot of investigation work on this matter; Guderian (1985), Skǎrby and Sellden (1985), Reich (1987). Highest ozone concentrations appear down wind of major cities and emission sources, but once ozone is mixed up and handed over into free troposphere it can be transported over large distances due to slow destruction processes and influence ozone levels also in areas faraway and free of anthropogenic emissions; Sexton and Westberg (1983), Puxbaum et al. (1991). The aim of this project was to investigate in situ ozone production in alpine valleys and to discriminate between the importance of ozone formation due to local emission sources and regional transport processes. To get an answer on the given question three valleys in Eastern central Alps (Austria) with different grade of traffic emissions were chosen; Gomiscek and Puxbaum (1991). Main investigations were performed in background area of the national park "Hohe Tauern", where a material cable car was used for measurement runs.
