T3 is a basic mast where ground surface temperature and air temperature (2 meter above ground) are measured. The mast was installed in October 2014. It is located 400 m above sea level on the slope of Skarvefjeld along the southwestern ridge. The ground surface is covered by rocks and soil with sparse vegetation. Time stamp refer to West Greenland Time (UTC-3). Missing ground surface temperatures in the period 2017-03-29 to 2017-07-07 are due to a cable cut by a rodent. Similar masts are found at other altitudes covering a gradient from 0 to 830 masl (T2-temperature_830m, T1-temperature_125m, T4-Temperature_1m) Meteorology:Meteorology GeoBasis Disko:The GeoBasis monitoring programme focuses on selected abiotic characteristics in order to describe the state of Greenlandic terrestrial environments and their potential feedback effects in a changing climate. Monitored plot data is up-scaled to a landscape level and is used to improve ecosystem models to be able to quantify these feedback mechanisms. The GeoBasis programme provides an active response to recommendations in international assessments such as ACIA and SWIPA; and is continuously being adapted based on AMAP and other international founded recommendations. Furthermore, the GeoBasis programme is directly involved in several international networks and research projects (e.g. the Circumpolar Active Layer Monitoring (CALM) programme, the Nordic Centre of Excellence DEFROST, the Danish Centre of Excellence CENPERM, the EU-projects PAGE21 and INTERACT, and the Arctic Research Centre at Aarhus University). The GeoBasis programme is divided into a number of sub-groups, including:
