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.
This web site provides general information on the GTN-P and details of
the permafrost thermal monitoring component. The second component of
the GTN-P is the ongoing Circumpolar Active Layer Monitoring (CALM)
network which was established in 1990 to monitor changes in active
layer thickness and temperature. Further information on the CALM
component can be found on the CALM web site. The European Community
project, Permafrost and Climate in Europe (PACE), contributes to the
GTN-P and plans to monitor nine boreholes in mountain permafrost.
Inventory Data of the candidate boreholes is kept by GTN-P for
Antartica, Argentina, China, Canada, Greenland, Italy, Kazakstan,
Kyrgyzstan, Mongolia, Norway, Russia, Spain, Sweden, Switzerland and
the United States.
