Description
Summary:This is a dataset of energy dissipation rates that were derived from turbulence measurements with a tethered balloon. A hot-wire anemometer package was operated during Legs 1, 2, and 3 of the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition. From the temporal high-resolution wind velocity records, energy dissipation rate (EDR) profiles were derived for non-overlapping 1 s time periods. With that, vertical profiles of the turbulence quantity are available for 34 days between 2019-12-06 and 2020-05-06 covering polar night and spring. The vertical profiles of turbulence measurements reach typically up to a height of several hundred meters (~200 m to ~1400 m).The data set contains not only the time stamps of the intervals used to calculate the EDR and the derived EDR values, but also the altitude values, the applied scaling coefficient and the upper bound of the inertial subrange. ...
