Dataset

Summary: The energy balance station IMK8T (Burnhaupt le Bas) measured high-frequency (20 Hz) eddy-covariance raw data with a Solent R1012 (Gill Instruments Ltd.) sonic anemometer above the target land use type corn. The measuring set-up was continuously running from 4 July to 25 August 2007 during the COPS measurement period in order to provide turbulent flux data of momentum and sensible heat. Post-processing was performed using the software package TK2 (developed by the Department of Micrometeorology, University of Bayreuth) which produces quality assured turbulent flux data with an averaging interval of 30 min. The documentation and instruction manual of TK2 (see entry cops_nebt_ubt_info_1) and additional references about the applied flux corrections and post-field data quality control (see entry cops_nebt_ubt_info_2) as well as a document about the general handling of the flux data can be found in supplementary pdf-files within the energy balance and turbulence network (NEBT) experiment of the data base. The turbulent flux data in this data set are flagged according to their quality and checked for an impact of possible internal boundary layers. Additionally, the flux contribution from the target land use type intended to be observed to the total flux measured was calculated applying footprint modeling. Information and references about the internal boundary layer evaluation procedure and the footprint analysis are also given in additional info pdf-files. Pictures of the footprint climatology of the station as related to the land use and to the spatial distribution of the quality flags are included in the corresponding additional info pdf-file (see cops_nebt_imk8t_info_1).

Description: To determine the accuracy of flux measurements, the sonic anemometer sensor type, as well as the classification of the turbulent flux data according to their quality (Foken et al., 2004) can be used (Mauder et al., 2006). Depending on the type of construction of the sonic anemometer, it can be classified as type A or type B (Foken and Oncley, 1995). The Solent R1012 sonic anemometer was classified as type B. In combination with the TK2 quality flags of the turbulent fluxes the accuracy of the flux measurements (sensible heat, for the friction velocity similar percentages can be assumed) can be assessed as follows:

For Type B (Solent R1012):
For quality flags ranging from 1 to 3:
Accuracy of sensible heat flux: 10 % or 20 Wm-2

For quality flags ranging from 4 to 6:
Accuracy of sensible heat flux: 15 % or 30 Wm-2
