Active layer and permafrost thermal state have been identified as key cryospheric variables for monitoring through the World Meteorological Organization’s Global Climate Observing System. An international network, the Global Terrestrial Network for Permafrost (GTNet-P), has been established under the Global Climate Observing System and is being developed by the International Permafrost Association. The active layer component, the Circumpolar Active Layer Monitoring (CALM) program, is already in place. Global Terrestrial Network for Permafrost organizational efforts are thus focused on the development of the permafrost temperature monitoring program, where Canada contributes actively through the Geological Survey of Canada’s membership on the International Permafrost Association organization and implementation committee. Although several regional permafrost borehole temperature networks exist, a globally comprehensive network for ground temperature measurements is required to provide long-term field observations essential for the detection of the climate change signal, for the assessment of its impact on permafrost, and for indications of spatial variability across the permafrost regions. 1 Resume : Les etats thermiques de la couche active et du pergelisol ont ete reconnus comme variables cryospheriques cles pour la surveillance dans le cadre du Systeme mondial d’observation du climat de l’Organisation meteorologique mondiale. Un reseau international, le reseau mondial terrestre pour le pergelisol (GTNet-P), a ete etabli dans le cadre du Systeme mondial d’observation du climat et est en voie de developpement par l’Association internationale du pergelisol. La composante couche active, soit le programme circumpolaire de surveillance de la couche active (CALM), est deja en place. Les efforts visant a organiser le reseau mondial terrestre pour le pergelisol sont donc centres sur l’elaboration d’un programme de surveillance de la temperature du pergelisol auquel le Canada contribue activement par la participation de la Commission geologique du Canada au comite d’organisation et de mise en oeuvre de l’Association internationale du pergelisol. Bien qu’il existe plusieurs reseaux regionaux de surveillance du pergelisol dans des sondages, un reseau de mesure de la temperature du sol a l’echelle du globe est necessaire pour obtenir les observations de terrain a long terme qui sont essentielles aux fins de la detection du changement climatique, de l’evaluation de son incidence sur le pergelisol et de l’obtention d’indications quant a sa variabilite spatiale dans les regions pergelisolees.
