Improving the Air Pollution Monitoring System in Graz, Austria by Additional DOAS Measurements Guest contribution D Baumgartner, A Gobiet, M. Mayer, R. Maderbacher, H. Pietsch and E Putz University ofGraz - Institute for Meteorology and Geophysics, Halbdrthgasse 1, A-8010Graz, Austria Introduction The response of air quality to air pollution, abatement strategies and changes in the emission of NO% and VOC have to be investigated by permanent and long- term monitoring. The analysis of measurements with respect to trends is complicated by the fact of non-uniform emission and inhomogeneous distribution of pollutants. The choice of measurement sites is therefore a crucial point, especially in urban areas. Remote sensing methods produce line integrated trace gas concentrations in contrast to conventional measurements at a single site. The time avera
