Global Permafrost Layers designed for Science On a Sphere (SOS) and WMS

Permafrost is permanently frozen ground that remains at or below 0°C for at least two years. The circumpolar permafrost and ground ice data depicts the distribution of permafrost and ground ice in the Northern Hemisphere and shows continuous, discontinuous, sporadic, and isolated permafrost boundaries.
