Abstract
Measurements of the uw covariance over the sea using the eddy correlation technique are used to compare two methods of correction when the mean “vertical” wind measured by the turbulence sensor is nonzero. A real-time continuous electronic correction is introduced and its performance assessed by evaluation of hourly mean values of the uw covariance and comparison with subsequent algebraically corrected values from a neighboring instrument. The validity of the algebraic correction is independently assessed by comparison of results from the two sets of instruments.
