The IPA releases the first global snapshot on permafrost temperatures

The International Permafrost Association releases the IPA-IPY Thermal
State of Permafrost (TSP) Snapshot Borehole Inventory, the first
comprehensive global inventory of permafrost temperatures as an output
of the International Polar Year

During the planning and implementation of the International Polar Year
(IPY) 2007 - 2009, the International Permafrost Association (IPA)
coordinated the acquisition of permafrost temperature data under the
Thermal State of Permafrost (TSP) Project #50. The TSP project goals
included the acquisition of standardized temperature measurements
(snapshots) from all permafrost regions on Earth, preparation of a
global data set, and development of maps of contemporary permafrost
temperatures. As a result of the project, networks of boreholes,
equipped for long-term permafrost temperature observations, were
established and consist of approximately 860 boreholes in both
hemispheres with more than 25 participating countries. Approximately 350
of the boreholes were drilled and instrumented during the IPY period
under various nationally funded projects. Comparison of the current Mean
Annual Ground Temperature (MAGT) and historical data allows
participating countries and other users to assess the thermal state of
permafrost dynamics over the last several decades. The TSP project also
included active layer measurements, many of which are observed annually
under the Circumpolar Active Layer Monitoring (CALM) project. The TSP is
a field component of the Global Terrestrial Network for Permafrost

The National Snow and Ice Data Center prepared the metadata and posted
the data set on its web site:
Data from over 500 of these boreholes were presented and discussed in a
series of papers in the special IPY - TSP issue of Permafrost and
Periglacial Processes
( that
include five regional papers and one synthesis paper. The main Data
Contributors of this data set were senior authors of these papers.
The TSP Snapshot Inventory was compiled and edited from individual
sources by Alexander Kholodov, Permafrost Laboratory, Geophysical
Institute, University of Alaska Fairbanks, and Jerry Brown, President
(2003-2008), International Permafrost Association.
