The combination of three approaches such as determination of turbulent heat fluxes with their corrections and quality tests, footprint model based quality assessment for the turbulent heat fluxes, and methods to measure the ground heat flux was discussed. The turbulent heat fluxes were calculated as the covariance between the two high frequency time series of vertical wind velocity and a scalar temperature, measured at one point in time. The latent turbulent heat flux was increased due to the Moore and WPL correction, whereas the sensible heat flux was decreased as a result of the Schotanus correction. The three approaches of quality assurance for energy flux measurement have a significant impact on the results of energy flux measurements.
