Global Terrestrial Network for Permafrost

Project Description
The Global Terrestrial Network for Permafrost (GTN-P) was initiated by the
International Permafrost Association (IPA)
( to organize and manage a global
network of permafrost observatories for detecting, monitoring, and
predicting climate change. The network, authorized under the Global
Climate Observing System (GCOS)
( and its associated
organizations, consists of two observational components: the active layer
(the surface layer that freezes and thaws annually) and the thermal state
of the underlying permafrost.
