	<productDescription>These data sets contain time series of wind speed, wind direction, air temperature, and relative humidiy, measured at the synoptic Lindenberg weather station (10393) during the Field Experiment on Sub-mesoscale Spatio-Temporal Variability in Lindenberg (FESSTVaL) from May to August 2021. The Lindenberg Meteorological Observatory – Richard-Aßmann-Observatory supersite is operated by the German national meteorological service (Deutscher Wetterdienst, DWD). Data are level-1 data as 10-minute averages (sums) based on 1 Hz sampling organized in daily files.</productDescription>
	<limitations>Data undergo standard quality checks implemented in the DWD synoptic station network. This includes range tests, plausibility tests with respect to neighbouring stations and to temporal changes. For temperature, a second sensor is operated for comparison. Each measured value is accompanied by a quality flag where 0 = data value missing, 1 = good quality, 2 = interpolated or gap-filled by data from an alternative sensor, 3 = dubious quality, 4 = bad quality, 9 = no quality information available. The wind measurements are performed at the top of a hill at the observatory site, the measurement place is surrounded by forest edges at distances of a few decametres to about 100 metres except for winds from SSW to NW, they cannot be considered as representative. </limitations>
