  • Ground thermal regime and permafrost distribution under a changing climate in Northern Norway
  • Climatic change ; Heat flow ; Model ; Northern Norway ; Norway ; Periglacial features ; Permafrost ; Soil temperature ; Spatial distribution ; Thermal regime
  • Since 2002, ground and ground surface temperatures have been systematically measured in the mountains of Troms and Finnmark, northern Norway. These data were used to calibrate and validate a transient heat flow model and a spatial permafrost model
  • in palsa mires seems to dominate. The study identifies 3 major permafrost regions in northern Norway : (1) maritime mountain permafrost in western Troms; (2) continental permafrost above the treeline and in bogs in Finnmark; and (3) Low Arctic permafrost
  • CryoGRID 1.0 : Permafrost distribution in Norway estimated by a spatial numerical model
  • Climatic change ; Model ; Norway ; Numerical model ; Periglacial features ; Permafrost ; Spatial distribution
  • CryoGRID 1.0 provides an equilibrium model of permafrost distribution in Norway at a spatial resolution of 1 km2. The approach was forced with gridded data on daily air temperature and snow cover. Ground thermal properties for different bedrock
  • that permafrost underlies sites mainly with exposed bedrock or covered by coarse-grained sediments, such as blockfields and coarse tills. In northern Norway, palsa mires are abundant and organic material and vegetation strongly influence the ground thermal regime
  • . Modelling suggests that permafrost in equilibrium with the 1981–2010 climate presently underlies between 6.1 per cent and 6.4 per cent of the total area of mainland Norway, an area significantly smaller than that modelled for the Little Ice Age climate (14
  • Permafrost in alpine rock faces from Jotunheimen and Hurrungane, Southern Norway
  • Altitude ; Climatic warming ; Heat flow ; Model ; Mountain ; Norway ; Periglacial features ; Permafrost ; Slope exposure ; Southern Norway ; Spatial distribution ; Surface temperature
  • To better estimate the thermal state of permafrost in steep rock walls in Norway, 5 temperature loggers were installed in 2009 and 2010, measuring the near-surface rock wall temperatures in vertical rock faces. Surface temperatures in rock walls
  • in Norway are on average higher than the ambient air temperature, by about 1° C in shaded faces to more than 3° C in faces with other aspects. An aspect dependency of rock wall temperatures is mainly visible during summer, with deviations of up to 4° C
  • Air and ground temperature variations observed along elevation and continentality gradients in southern Norway
  • Air temperature ; Altitude ; Continentality ; Mountain ; Norway ; Periglacial features ; Permafrost ; Soil temperature ; Southern Norway ; Temperature ; Thermal regime
  • The coupling between air and ground temperatures in the mountains of southern Norway was examined using 12 shallow boreholes drilled in August 2008. Three borehole arrays (at Juvvass, Jetta and Tron), each with boreholes at different elevations
