Windowed Inspection of Stationarity and Quality (WISQ): An Algorithm for Eddy Covariance Sample Quality Control and Assessment
Abstract
Measuring atmospheric fluxes requires various steps of measurement quality control, in addition to experimental design andpost-processing corrections, in order to provide robust and high-fidelity data for wider use. However, within the measurementcommunity, methods for these control steps are still applied ad hoc. Regardless of the availability of several comprehensivereferences texts available in the literature and licensed software programs. The theoretical and technical design of an algorithmfor eddy covariance flux sample quality control and assessment is presented. This algorithm, WISQ, is robust and efficient andcan be readily incorporated into existing processing experimental software packages. The goal of this algorithm is to output aflagging system that can be used to judge the quality of individual flux samples, with the option for outputting more detailedinformation. WISQ is unique in that it directly and automatically assess the sample flux accumulation and convergence. WISQis also a general method that can be utilized for flux measurement outside of the realm of meteorology and is open-sourced forease in development and innovation.
