Validation of nitrogen dry deposition modelling above forest

  • Accurate modeling of nitrogen (N) deposition is essential for identifying exceedances of N and defining critical values in environmental protection guidelines.


  • However, there are still uncertainties in modern deposition routines due to a limited availability of long-term flux measurements of reactive nitrogen
    compounds for model development and validation.


  • We investigated the performance of dry deposition inferential models with regard to annual budgets and the exchange patterns of total reactive nitrogen (ΣNr) at a low-polluted forest located in the Bavarian Forest National Park, Germany.
