   Temperature versus depth measurements in boreholes on the Canadian Prairies were originally measured some two decades ago (1987). They were repeated a decade ago and were then repeated from 2005 to 2007. Modelling of the synthetic temperature-depth transients shows that the time variation of subsurface temperature follows variations in surface air temperature (SAT). The surface-temperature increases of 0.2 and 0.4 °C are observed for time scales of one and two decades, respectively. The top of the atmosphere solar irradiance data recorded by satellite since 1978 was computed at the locations of the repeated temperature measurements to calculate a forcing signal to allow subsurface temperatures to be modelled, as previously done with SAT data.
