Flux calculation of short turbulent events in Chersky in the Sakha (Yakutia) Republic, Far Eastern Federal District of Russia C. Schaller, M. Göckede, and T. Foken https://doi.pangaea.de/10.1594/PANGAEA.873260

Short summary
The eddy covariance (EC) method allows for measuring and calculating vertical turbulent exchange fluxes between ecosystems and the atmosphere. It fails in non-steady-state flow conditions, e.g. in Arctic regions. Two alternative calculation methods, conditional sampling and wavelet analysis, were implemented and compared to EC. Wavelet analysis for allows calculating a trustworthy flux even in non-stationary times and offers new possibilities for exact flux calculation in difficult environments.
