Soil temperature @ 0cm - 60min average (°C)

1995-08-17 → 2024-12-31 zackenberg-research-station Greenland Ecosystem Monitoring CC BY-SA 4.0

Soil temperature is measured using Campbell Scientific 107-L temperature probes inserted at the given depths in the ground. A single sensor measures at each depth. Please read the metadata file provided with the data for comments related to the data in this timeseries.

    Data comments: 1995-1999: Data from the upper three sensors are very similar (daily amplitudes of temperatures are almost the same). Could be related to percolating water or because the tube with sensors was not completely covered/below ground. Data is suspect. 1995-2015: Data in this period has earlier been published with a correction according to the autumn zero curtain. Since June 2020 the original non-corrected data from this period is published. 2004-2006: Data deleted or suspect due to high frequency fluctuations (noise) in data related to unstable battery charge or broken sensor. August 2006: all sensors were replaced, new sensors installed in a new hole. 2013: Change of measuring method in logger program (from 250 Hz to 50 Hz) in August caused a shift in data. 2015-2018: in 2015 sensors down to 5 cm were dug free. After this the two upper sensors seem to be disturbed or located a

  • Quality Flag
    Flag assigned during quality control. Flag = "fair" is assigned instead of good to indicate where a value is interpolated, or, where only 1 timeseries has been used where it is normal to take the average of 2 timeseries. Flag = unknown is equivalent to the flag "good" or "fair" and is due a change in proceedures. Work is underway to update these flags.
