Online data: Global Permafrost Zonation at 1km

There is a Global Permafrost Zonation Index at 30 arc-second (<1km) resolution is available online at:

A kmz file for Google Earth, the address of a Web Mapping Service and raw data are provided.

The derivation of the dataset is described in this publication In it, issues of uncertainty and heterogeneity are discussed in detail. These are especially important when using such data for validating other models. Updated statistics for global/national permafrost areas as well as plots detailing the nature of permafrost areas in terms of latitude, elevation, heterogeneity and terrain ruggedness are available and include an estimation of uncertainty.
