Shroud Experiment 2020

This dataset contains the data used for the paper titled "Toward quantifying turbulent vertical airflow and sensible heat flux in tall forest canopies using fiber-optic distributed temperature sensing".

This first part of the dataset contains the experiment conducted between April 2020 and June 2020 at the Ecological Botanical Garden (EBG) at the University of Bayreuth. Two upside-down sonic anemometers (Model USA-1, Metek GmbH, Elmshorn, Germany) at 1.5 m height (middle of the shroud) and two quad disk pressure ports attached to a nano resolution digital barometer (Model 745-16B, Paroscientific, Inc.) at 1 m above ground set up; one of each sensor placed inside the cylindrical shroud. The sonic anemometer and static pressure data recorded at sampling frequencies of 20 Hz.

The second part of the dataset contains the experiment conducted at the Waldstein-Weidenbrunnen long-term ecosystem flux site between October 2020 and November 2020 as part of the LOEWE20 (Large Eddy ObsErvatory Walsstein Experiment 2020) experiment. Two high-resolution DTS instruments (Model 5 km Ultima, Silixa, London, UK) used to observe the continuous temperature with a spatial resolution of 0.127 m averaged over 6 seconds. Quartet FO array containing two pairs of parallel coned and unconed FO cables extending from the ground to the top canopy at 34 m and 36m height for main and turbulence tower.
