Processing and quality control of flux data during LITFASS-2003 (2006, methodology): “Algorithms for these procedures are available (Webb et al. 1980; Schotanus et al. 1983; Moore 1986; Wilczak et al. 2001) and have to be applied during the post-field data analysis.”
Towards a consistent eddy-covariance processing: an intercomparison of EddyPro and TK3 (2014, methodology): “We decided to apply two different tilt corrections for the two data sets: double rotation for the open-path system and planar fit for the closed-path system (Wilczak et al., 2001) in order to test the agreement between the two packages with both methods.”

(2001), if not already implemented in sensor software; the ‘‘planar fit’’ method for coordinate transformation (Wilczak et al. 2001); a correction of oxygen cross sensitivity of kryptonhygrometers (Tanner et al. 1993, van Dijk et al. 2003); spectral…”
Analysis of second‐order moments in surface layer turbulence in an Alpine valley (2009, background): “Streamwise alignment One of the procedures most frequently adopted in the analysis of surface layer turbulence measurements, especially when dealing with flows over complex terrain, is the so called streamwise alignment (McM; Kaimal and Finnigan, 1994; Cassardo et al., 1995; Wilczak et al., 2001).”

Part II: Intercomparison of eddy-covariance sensors and post-field data processing methods (2007, methodology): “Most of the processing steps and flux corrections are well described in the literature (e.g. Webb et al. 1980; Schotanus et al. 1983; Moore 1986; Højstrup 1993; Tanner et al. 1993; Wilczak et al. 2001).”
Some methodological questions concerning advection measurements: a case study (2007, methodology): “(a) A static offset (i.e., a non-zero ¯ w in the absence of wind) may appear due to electronic problems (Grelle and Lindroth 1994; Lee 1998; Wilczack et al. 2001 ).”

Flux calculation of short turbulent events – comparison of three methods (2016, methodology): “…these outliers gets explainable, when taking the method’s use ofw into account: eddy covariance and wavelet analysis both base on the correlation betweenw and c, for eddy covariance there is the additional requirement of w̄c̄ = 0 over the averaging period or in the long term (Wilczak et al., 2001).”
Comparison of two methods to derive time series of actual evapotranspiration using eddy covariance measurements in the southeastern Australia (2012, methodology): “Post-processing steps included spike detection (Vickers and Mahrt, 1997), planarfit coordinate rotation (Wilczak et al., 2001), air humidity corrections for sensible heat flux (Schotanus et al.”
