The deposition of nitric oxides into a spruce stand at the Tharandt Forest, near Dresden, Saxony, was analysed. Eddy Covariance measurements, standard meteorological measurements and concentrations of nitric oxides of the anchor station nearby were available as model input. We used a resistance analogy model with a location-specific parametrisation for the resistances of transport to determine the deposition rates of NO and NO2 for 1998 and 1999. The annual sums of deposition of NO2-N average between 0.96 and 1.16 kg/(ha*a) for 1998 and between 1.12 and 1.35 kg/(ha*a) for 1999. These results match well results of other studies from sites with similar characteristics. As expected, the comparison of the results of a diurnal-based model (DM) with a 30 min model (HHM) shows a better adaptation of the HHM. However, due to the better availability of daily data it is necessary to use the daily model for the estimation of long term entries beyond the period of parametrisation.
