It measures the three components of the wind (u, v and w measured in m/s) and the sonic temperature (expressed in Kelvin degrees) at a rate of 20 Hz. These micro-meteorological measurements are complemented by standard meteorological ones at 4 levels: 2, 5, 10 and 33 m (acquisition time step 1 minute).

Create an image with a map or graph of a subset of the data. mapDigital dataset Wind components and sonic temperature measurements were used to estimate friction velocity and kinematic heat flux. Before computing the micrometeorological parameters, a preliminary analysis is applied in order to assess the data quality and to remove low quality records. The quality control procedure (inspired to Zahn et al. (2016)) was applied to 30-minute data blocks following different steps: (i) COMPLETE RECORD TEST; (ii) BOUND TEST; (iii) SPIKES TEST; (iv) STATIONARITY TEST; MISSING VALUE TEST (v).
