Tropospheric Chemistry: Results of the German Tropospheric Chemistry Programme

The formation, transport and impact of photo-oxidants, e.g., ozone, is a major environmental problem in densely populated areas with corresponding high emissions of ozone precursor substances such as NO_x and volatile organic carbon compounds (VOC).

Although major progress has been achieved within the last decade, there are still significant uncertainties in our understanding of the chemical behavior of the polluted atmosphere, in particular the interaction between cities and surrounding area...
