Nitrogen oxides emissions from european forest ecosystems

Objective

The source strength of EU forests for the primarily and secondarily active N-oxides N20 and NO is highly uncertain. However, recent investigations have shown that EU forests, due to high rates of atmospheric N-deposition in the last decades, are significant sources for N-oxides. Based on results obtained from field and laboratory experiments on the characterisation of N-oxide fluxes in different forests (e.g. climate, soil, forest type) we will further improve and validate
a) a mechanistic model and
b) a canopy exchange model for predicting N-trace gas emissions at the soil-atmosphere and canopy-atmosphere interfaces. After combination of both models, we will calculate EU wide inventories of N-oxide emissions from forests with hitherto unknown precision and, using scenarios for future changes in climate and N-deposition, predict future changes in N-oxide emissions.
