| contents | The eddy covariance method is commonly used to calculate vertical turbulent exchange fluxes between ecosystems and the atmosphere. Besides other assumptions, it requires steady state flow conditions. If this requirement is not fulfilled over the averaging interval of, e.g., 30 min, the fluxes might be mis-calculated. Here two further calculation methods, conditional sampling and wavelet analysis, which do not need the steady state assumption, were implemented and compared to eddy covariance. All fluxes were calculated for 30 min averaging periods, while the wavelet method - using both the Mexican hat and the Morlet wavelet - additionally allowed to obtain a 1 min averaged flux. The data sets used for this investigation are published with 20 Hz sampling frequency. |
