Introduction

Decadal changes in permafrost temperatures and depth of seasonal freezing/thawing are reliable indicators of climate change in high latitude and mountain regions. Warming may result in a reduction in the extent of permafrost and can have an impact on terrain stability and moisture and gas fluxes. Like glaciers, mountain permafrost and seasonally-frozen ground can also provide a significant contribution to summer water availability. Standardized in situ measurements are essential, both to calibrate and to verify regional and global climate change.

ECV biomass standards report

As requested by UNFCCC SBSTA/COP for its 23rd Session in Montreal, November 2005, GTOS is undertaking the assessment of the status of the development of standards for each of the essential climate variables in the terrestrial domain. The following report, documentation and other material have been compiled for permafrost. We very much welcome your comments and inputs in improving and completing the analysis. Please send any material and comments to the GTOS Secretariat.
