Relaxed eddy accumulation outperforms Monin‐Obukhov flux models under non‐ideal conditions
Abstract The Monin‐Obukhov Similarity Theory (MOST) links turbulent statistics to surface
fluxes through universal functions. Here, we investigate its performance over a large lake …

An analog period method for gap‐filling of latent heat flux measurements
LEB Hoeltgebaum, NL Dias… - Hydrological Processes, 2021 - Wiley Online Library
Practically all records of eddy‐covariance flux measurements are affected by gaps, caused
by several reasons. In this work, we propose analog period (AP) methods for gap‐filling, and …
