WLEF High-Frequency Flux Data



This dataset contains the 10 Hz turbulent time series of sonic anemometer 3D winds, CO2, CH4 and H2O concentrations from the WLEF-TV US-PFa Park Falls very tall Ameriflux tower over the Chequamegon Heterogeneous Ecosystem Energy-balance Study Enabled by a High-density Extensive Array of Detectors (CHEESEHEAD) observation period. Raw data is sonic coordinate system, while corrected is after planar fit rotation and lag time correction.  Note that corrected data files have "rotated_lagged" in the file names. This dataset has quality assurance and quality control applied that follows the University of Wisconsin standard tower practices and is reviewed by the DOI Ameriflux program. Plausible ranges, sensor quality flags, suspect periods, known maintenance times, and sensor flatlines are all identified and suspect data are removed. Data streams are also visually inspected for additional outliers. See the related links for the Berger et al 2001 J Tech publication to learn more about how this dataset is qualtiy controlled.
