attribute NC_GLOBAL history String 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). See full report for the details.

attribute NC_GLOBAL summary String Turbulent parameters are measured at the Amundsen-Nobile Climate Change Tower (CCT) by means of a Gill R3 sonic anemometer installed at 7.5 m from the ground since 2010. 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).
