The mounting heights given in the comment section for each parameter are those at the time of maintenance (2017-01-04). Questionable data has been flagged. The mounting pole of the wind vane was tiltet by 90° to the west (axis of rotation of wind vane was horizontally) when the station was visited for maintenance on 2018-01-10. The issue seems to start latest on 2017-11-03, but wind measurements might already be affected earlier. The thermometer/hygrometer seems rimed from the 2017-04-04 until the maintenance on 2018-01-10. Humidity measurements in this time need to be disregarded. Temperature measurements will be affected as well, e.g. inertia due to the rime cover of the instrument.
