Quantifying how variation in surface properties between pristine mires and forests contribute to the differences in their land surface temperature (LST) is important to understanding the potential biophysical effects of peatland restoration. We attributed the difference in LST between a boreal mire and forest to the differences in their biophysical properties: albedo, energy storage, aerodynamic resistance and bulk surface resistance to evapotranspiration. We propose a novel modification to a widely used attribution methodology, resulting in substantially improved model accuracy. The results indicate important differences from previous comparisons between low-vegetation and forest ecosystems. In the northern boreal zone, the higher mire albedo during the snow-covered period had a substantial impact on the LST difference. While the reduced turbulent mixing over an open mire has a strong daytime warming contribution during the growing season, the higher evaporation potential of the mire induces a considerable cooling effect. Differences in heat storage changes were not important contributors to the difference in daily mean LST.
