The mounting heights given in the comment section for each parameter are those at the time of deployment (2015-12-28). The automatic weather station was maintained and raised by 0.90 m on 2018-01-10. This raised all instruments by approximately 0.13 m; hence the mounting heights on 2018-01-10 are those given below plus 0.13 m. Questionable data has been flagged. Main limitations are seen in: 1) Long-wave radiation measurements are affected by rime mostly during the austral winter; 2) The ventilation of the thermometer/hygrometer is insufficient when sunny days are accompanied by low wind speeds. 3) Datalogger issues with the internal voltage reference caused peaks in pressure and wind direction measurements until 2018-01-10. These are marked as invalid data. ...
