Abstract
As part of the quality assurance and quality control activities within the CarboEurope-IP network, a comparison of eddy-covariance software was conducted. For four fiveday datasets, CO2 flux estimates were calculated by seven commonly used software day packages to assess the uncertainty of CO2 flux estimates due to dierences in postprocessing. The datasets originated from diverent sites representing dierent com- commonlyapplied instrumentation and dierent canopy structures to cover a wide range monly of realistic conditions. Data preparation, coordinate rotation and the implementation of the correction for high frequency spectral losses were identified as crucial processing steps leading to significant discrepancies in the CO2 flux results. The overall comparison indicated a good although not yet perfect agreement among the dierent software within 5–10% dierence for 30-min CO2 flux values. Conceptually dierent ideas aboutthe selection and application of processing steps were a main reason for the diverences in the CO2 flux estimates observed. A balance should be aspired between scientific freedom on the one hand, in order to advance methodical issues, and standardisation of procedures on the other hand, in order to obtain comparable fluxes for multi-site synthesis studies.
