Permafrost: Circum-Arctic Map of Permafrost and Ground Ice Conditions

Permafrost: Circum-Arctic Map of Permafrost and Ground Ice Conditions

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.
