Online data: Global Permafrost Zonation at 1km

Stephan Gruber
Dear all

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.

Kind regards,

PS: I have no idea how the GIS server performs when subject to many parallel requests. If Google Earth of the Web Mapping Service become slow, please retry after a few days.
