Turbulent transport extraction in time and frequency and the estimation of eddy fluxes at high resolution Abstract. We introduce a novel framework for estimating eddy fluxes using cross-scalogram smoothing, addressing key limitations of the standard eddy-covariance method. The standard approach suffers fr...
