The data are from a test section of the Beaver Creek experimental road site (BC-RES) (62° 20' N; 140° 50' W; 649 m a.s.l.). The dataset covers the period 1/10/2008 - 31/12/2018. The thermistor strings (accuracy of ± 0.1 °C between -10 °C to +10 °C; ± 0.2 °C between -50 °C to -10°C and +10°Cto 30 °C) were installed in 9.7-m deep boreholes located at the centerline of the road and in the slope of the unmitigated embankment (YG4 Original). Detailed descriptions of the test section can be found in Coulombe et al. (2012), Malenfant-Lepage et al. (2012) and Stephani (2013). The ground temperature measurements (°C) were at 4-hour intervals.
