Abstract: 
Reactive atmospheric nitrogen species contribute to adverse effects in ecosystems (acidification and eutrophication) and in the troposphere (ground level ozone and secondary particle formation, both leading to further adverse effects to ecosystems and human health). However, dose-response relationships are not at all well established. In a comprehensive approach for the German federal state of Hesse, emissions, atmospheric concentrations and chemistry as well as deposition fluxes are assessed by a matching set of models and measurements, aiming at a regionally closed nitrogen balance. Measurements cover all reactive species, the respective source and sink properties and the meteorological parameters relevant for model operation and validation: gaseous ammonia, nitric oxide, nitrogen dioxide, nitrous and nitric acids as well as ammonium and nitrate in aerosols and sedimenting particles. This paper describes the challenge, i.e. the present deficits in knowledge, and derives a methodological approach and the practical means applied or planned (locations, equipment, procedures) in principle.
