This data set contains a global (excluding Antarctica) 1 km map of permafrost zonation. It is an estimate of to what degree permafrost exists in a region nearly everywhere, or only in the most favorable conditions. These local conditions affecting permafrost occurrence will partly exhibit regional...
The circumpolar permafrost and ground ice data contribute to a unified international data set that depicts the distribution and properties of permafrost and ground ice in the Northern Hemisphere (20°N to 90°N). The re-gridded data set shows discontinuous, sporadic, or isolated permafrost boundaries.
