Soil temperature is measured in 0, 10, 50 and 118 cm below the surface on a gravel plateau. The soil temperature sensors were installed in 1995. Temperature was initially recorded every fifth hour until 1996, then every second hour until 2005, whereafter it has been recorded every hour all year round. Blank cells are missing data.
The sensor has broken on several occasions:
2000, replaced in 2001.
2004, replaced in 2005.
2005, replaced in 2006.
2006, replaced in 2007.
Data from summer 2015 to summer 2016 is missing, due to erroneous data download.
