Spatial and temporal variations in thermal resistance of snow in the territory of Russia for the period from 2001 to 2010 has been studied and mapped from data of snow surveys. Long-term means of snow thermal resistance and freezing index for 2001–2010 were compared with the respective values for 1966–2000. The thermal resistance of snow was found out to control the thermal stability of permafrost and to vary geographically. Areas with favorable and unfavorable conditions for permafrost preservation were identified.
