Datasets

RAWDATA

Uncorrected 1-min raw data, no quality checks applied

EDIRE_L2AND3

30-min turbulence statistics (former processing with Edire) Processed turbulence data with an averaging interval of 30 min for the two uppermost turbulence measurement levels at 10 and 30 m (processing was performed using EdiRe)

Processing includes despiking; double-rotation of the wind components; detrending with a recursive filter and a time constant of 200 s; and applying frequency-response corrections, heat-flux corrections for humidity effects, oxygen corrections for KH20, and WPL corrections. The datafile contains several quality flags.

EDIRE_L1

30-min turbulence statistics (former processing with Edire) Processed turbulence data with an averaging interval of 30 min for the bottom turbulence measurement level at 4.0 m (processing was performed using EdiRe)

Processing includes despiking; double-rotation of the wind components; detrending with a recursive filter and a time constant of 200 s; and applying frequency-response corrections, heat-flux corrections for humidity effects, oxygen corrections for KH20, and WPL corrections. The datafile contains several quality flags.
