QA/QC for Carbon Dioxide Flux Measurements

CARBOEUROPE-IP

From 01/2004 to 12/2006

Principal Investigator: Thomas Foken
Staff: Mathias Göckede, Matthias Mauder, Florian Wimmer

Activity 'Quality control and improvement of eddy flux data'

Task 1.2.1 Footprint and quality assessment of main flux sites:
Each of the Main Sites of the cluster flux network will be evaluated by means of quality checks on eddy covariance data as well as for the representativeness of the fluxes of the respective footprints. To this purpose each Main Site footprint will be evaluated on the basis of a georeferenced land use/cover digital map. This information will be provided to the flux database as additional information for modellers as well for further flux corrections and error analysis.

Task 1.2.2 Improvement of quality control procedures on eddy covariance data:
New methodological components (planar fit rotation, ogive-test) as well as suitable quality control procedures will be developed. An high quality sensor set-up and associated methodical issues will be developed to investigate the energy balance closure as a control method for eddy covariance measurements. The Waldstein-Weidenbrunnen site of the University of Bayreuth will be used as a data quality test station.
