Temporal dynamics of reactive nitrogen fluxes over different ecosystems

• Field campaigns were carried out to test novel measurement techniques in eddycovariance setups for continuous determination of NH3 and total reactive nitrogen fluxes.

• While high-frequency concentrations of NH3 were measured with a quantum cascade laser absorption spectrometer (QCL), a custom-built converter coupled to a chemiluminescence detector.

• Campaigns were conducted above cropland (TI) , forest (BF) and peatland (BM) ecosystems.
