T1-Soil temperature consist of temperature sensors installed in a soil pit. The sensors were installed in August 2018 . The soil pit is located on the top of Pjeturssons moraine ridge (125 meter above sea level) on a surface covered by low dwarf shrub vegetation. The time stamp refer to UTC-3. A major gap from 17 September 2019 to 4 July 2020 is due to a battery failure. Data are logged by 1 hour intervals. Soil surface temperature and air temperature in 2 m are measured at the same site under Meteorology (T1_Temperature_125m).
