PACE, Permafrost and Climate in Europe,established a series of monitoring sites in a north-south transect across Europe. One selected site is located c. 1 km east of Tarfala Research Station. A 100 m deep bore hole was drilled at a location c. 1550 m a.s.l. to monitor permafrost temperature. An accompanying 15 m bore hole was also drilled in which near surface temperature showing annual variations is monitored.
