Averaging, Detrending, and Filtering of Eddy Covariance Time Series,een seen to be a relatively straightforward task and the methods are well known. Such re-processing can result in the loss of real signal since the detrending and averaging methods act as high-pass filters. We review the main methods used to separate the active, turbulent transport that we treat asGourmet 发表于 2025-3-23 18:03:38
Coordinate Systems and Flux Bias Error, coordinate system, and the overall coordinate frame consisting of the vector basis and coordinate lines, a global property of the flow that is determined by the flow field in three dimensions. Point measurements can only define the vector basis. Because in field campaigns many components that enter严厉批评 发表于 2025-3-24 02:13:16

Concerning the Measurement of Atmospheric Trace Gas Fluxes with Open- and Closed-Path Eddy Covariane terms resulting from concurrent heat and moisture fluxes, the so called ‘density’ or ‘WPL corrections’ (Webb et al. 1980). The theory behind these additional terms is well established. But, virtually no studies to date have examined the constraints imposed on the theory by different instrumentatioFocus-Words 发表于 2025-3-24 17:53:39
