Reply to comment by Mauder on "How well can we measure the vertical wind speed? Implications for fluxes of energy and mass"
Kochendorfer, John; Meyers, Tilden P.; Frank, John M.; Massman, William J.; Heuer, Mark W. 2013. Reply to comment by Mauder on "How well can we measure the vertical wind speed? Implications for fluxes of energy and mass". Boundary-Layer Meteorology. 147: 337-345.
In Kochendorfer et al. (Boundary-Layer Meteorol 145:383398, 2012, hereafter K2012) the vertical wind speed (w) measured by a non-orthogonal three-dimensional sonic anemometer was shown to be underestimated by 12%. Turbulent statistics and eddycovariance fluxes estimated using w were also affected by this underestimate in w. Methodologies used in K2012 are clarified here in response to Mauder's comment. In addition, further analysis of the K2012 study is presented to help address questions raised in the comment. Specific responses are accompanied with examples of time series, calculated correlation coefficients, and additional explanation of the K2012 methods and assumptions. The discussion and analysis included in the comment and in this response do not affect the validity of the methods or conclusions presented in K2012.
Keywords: angle-of-attack error, cosine error, eddy covariance, energy balance closure, sonic anemometer, transducer shadowing
