CALM GRID & Boreholes

Calm Grid monitoring site

The monitoring of permafrost and active layer conditions: characterization of snow coverage, vegetation and the snow conditions is performed at the CALM GRID site close to the CCT.

The measurements consist in measure with a snow probe in correspondence of each of the 36 nodes of the grid within an area of 50x50 m with a span of 10 m. A digital snow camera installed during SSF-SFG project SMAC on the the CCT collects images of the surface seasonal variation all over the year. At the corners of CALM GRID 4 boreholes 6 m deep and one 50 m deep have been drilled and equipped with thermistors chains to measure the temperature profile in the permafrost, with higher resolution in the activelayer.
