Station History

• 07th October 2010: Installation of the station ~10 m west of the hut. Air temperature and humidity probe in Stevenson Screen. (Lat: 46.798613; Lon: 10.760417; 3026 m)
• 17th August 2017: Pluviometer installed at current location. Lots of data gaps until October 2020.
• 11th November 2020: Station at current location (~35 m in distance from old location); instruments renewed/replaced
• 14th September 2021: Soil temperature probes burried (exposed to atmosphere before) and FlowCapt Sensor mounted.

Data Quality notes

• Quality issues with soil temperatures from June 2019 (exposed to atmosphere) until 15.09.2021 (newly installed)
• No quality value measured for SR50 snow depth before 04.03.2022

• Only for dataset PANGAEA: Apply atmospheric pressure correction for values measured before 20.02.2020 13:30 due to wrong offsets and multipliers in logger program

  P_corr = P*(0.2/0.24)+((-0.2/0.24*500)+600). Corrected atmospheric pressure values should be around 700 hPa
