The overall uncertainty in annual flux estimates derived from chamber measurements may be as high as 50% due to the temporal and spatial variability in the fluxes (Flechard et al., 2005). As even a large number of chamber plots still cover typically less than 1% of the total field area, the field-scale integrated emission necessarily remains a...

Global atmospheric concentrations of CO2, CH4 and N2O have increased markedly as a result of human activities since 1750 (30%, 150% and 17% respectively). The global increases in carbon dioxide concentration are primarily due to fossil fuel and land-use change, while those of methane and nitrous oxide are primarily due to agriculture (IPCC, 2007...

A quantum cascade laser was evaluated for eddy covariance measurements of CH4 and N2O using laboratory tests and three months of continuous measurements. Moreover, an indication was given of CH4 and N2O exchange. All four required criteria for EC-measurements related to continuity, sampling frequency, precision and stationarity were checked. The...

A quantum cascade laser spectrometer was evaluated for eddy covariance flux measurements of CH4 and N2O using three months of continuous measurements at a field site. The required criteria for eddy covariance flux measurements including continuity, sampling frequency, precision and stationarity were examined. The system operated continuously at...
