Abstract

Analysis of polluted ozone in a mountain area P. Bonasoni & P. Cristofanelli Institute of Atmospheric and Oceanic Sciences, National Research Council, via Gobetti 101, 40129 Bologna, Italy Abstract The surface ozone concentration at the Mt. Cimone station (44° 12' N, 10°42' E, 2165 m a.s.l.) presents a behaviour typical of a high mountain area. In spite of its baseline conditions Mt. Cimone can be affected, during the summer, by transport phenomena of polluted air masses bringing high ozone concentration harmful to human health and dangerous for the vegetation system. In order to quantify the contribution of the polluted air masses on the background ozone concentration, we present an analysis on four year ozone and carbon monoxide data, three- dimensional backward trajectories and meteorological parameters. In this work we separated the trajectories coming from tropospheric low levels (below 780 hPa) inside the Po valley box area during the warm season (May-September). This analysis
