    Temporal and spatial representativeness of the atmospheric boundary layer profiles

  • Annotation in Czech

    The project deals with spatiotemporal representativeness of the atmospheric boundary layer profiles. ABL profiles measured by various instruments will be compared and synthetized to provide tables of parameters for typical situations. Several objectives will be solved to achieve the main goal. • A critical overview of existing datasets (together with the international partners). • Identifying the ABL parameters important for the wind engineering community and defining their derivation from various instrument measurements (together with the international partners). • Compilation of the quality datasets and derivation of the ABL parameters as a function of surface characteristics and thermal stratification. • Testing of a real-site model of a measurement site in the wind tunnel. Temporal and spatial representativeness of the ABL profiles will be quantified by comparison of the field and wind-tunnel datasets. • Detection of coherent structures based on different variables in field datasets and identification of links between them. Dependence of the length and the energy of the coherent structures as a function of surface characteristics and a thermal stratification. • Synthesis of the results, their presentation within the COST Action and on the international conferences, and publication in impacted journals.

  • Project results evaluation

    In 2023, wind tunnel experiments continued and data from both tunnel and mast measurements were analyzed. We showed a strong connection between temporal and spatial organized structures. We also analyzed the effect of a wake behind the mast on the anemometer measurements. We have been actively involved in scientific and organizational activities within the European project COST CA18235.
