i-Box Surface Energy Balance fluxes

Datasets used for the data analysis in the paper "Characterization of the Surface Energy Balance Residual in Complex Terrain". The datasets were produced based on 20 Hz high-frequency data and low-frequency measurements from the i-Box network (Inn Valley, Austria), using a post-processing Python software. According to Rotach et al. (2017): df_101.csv: valley floor site, VF0 (Kolsass) df_103.csv: south facing site, SF1 (Eggen) df_104.csv: north facing site, NF10 (Weerberg) df_105.csv: north facing site, NF27 (Hochhaeuser) df_106.csv: mountain top site, MT21 (Arbeser) df_168.csv: south facing site, SF23 (Stanser Joch) Turbulent statistics and fluxes are computed using a 30 min averaging window, using: Procedure Method and reference Coordinate rotation Sectorial planar fit (Yuan et al. 2011; Oldroyd et al. 2016) Filtering High-pass recursive digital filter (Falocchi et al. 2018) Flux corrections Frequency response correction (Moore 1986) Humidity correction for sensible heat flux (Schotanus et al. 1983) Density correction (Webb et al. 1980) Oxygen correction (van Dijk et al. 2003) Quality criteria Instrument diagnostic (Stiperski and Rotach 2016) Skewness and kurtosis thresholds (Vickers and Mahrt 1997) Stationarity (Foken and Wichura 1996) Uncertainty controls (Stiperski and Rotach 2016)
